          You're making too much of this. Between 4.0 and 4.1 isn't that big-a change. The only reason why it took so long for many distros to move between 3.3 and 3.4/4.0 was the change in the binary interface between the compilers. In other words a program compiled with 4.0 couldn't link to a library compiled with 3.3. There isn't this restriction between 4.0 and 4.1 so there's no reason why it can't go into the repositories straight after testing.

              No actually that's wrong, if only slightly. GCC 3.3.* and below use a different C++ ABI to GCC 3.4, 4.0, and 4.1. Even Debian has upgraded from GCC 3.3 to GCC 4.0 so an incremental version upgrade shouldn't be too much of a deal.

      GCC is an impressive piece of software - either considered asopen source or in general. A lot of people preffer more "serious" C/C++ compilers, like Intels', but it's a remarkably good compiler by itself, very fast, produces stable and well optimized code AND it is available for every platform you could dream of developing on. Ah, and constantly improving support for other languages (specially Java) is a nice perk aswell :)

          It's safe to say that if we have a healthy OSS community, is because of the great developing tools available on OSS platforms. GCC is a strong contender for that crown, IMHO.

        I saw some benchmarks a few months ago that closes the gap in performance in c/c++ performance with gcc/g++ 4.0 and the Intel compilers.

        Intel wrote them when gcc2.95 was still out and c++ performance was not that good nor was it truly modern ansi compliant by the iso. For example things like the STL were merely emulated and performance for non x86 cpu's was behind too.

        With gcc3.x and now gcc4.x its fully caught up in almost all area's. Its nice now to have a nice c/c++ compiler for the alpha and mips processors that produce fast code.

        I wonder if the rise of Linux and Free software is what made the compilers catch up?

        By the way the Intel compiler is still the way to go for Fortran.

        Yes, gcc is a great compiler, but it is not as good as a commercial compiler like Intel's, or PathScale's, or the Portland groups' or another compiler that is designed for a specific platorm.

        I use it by default on my Itanium, Alpha, x86, and SPARC systems, but when performance matters, I go for one that is better optimized.

        The most grateful aspect of gcc to the world is that Linux would be impossible without it. And that in itself is enough. I learned C from using gcc, and like I said, I use it daily, but it is not the best performing compiler on the block. It is not uncommon to get up to 100% speedup using an optimized compiler for the platform over gcc, but for portability and familiarity of the compiler across platforms (which is its purpose), it is damn good. Especially when many vendors do not provide a C/C++ compiler for their OS without extra charge.

        Thank you GNU and the gcc people.

            I've spent quite a bit of time hacking on gcc, and I'd say my biggest complaint is that a lot of the gcc code really sucks. It's chock full of gigantic impossible-to-understand chunks of code -- few comments, huge numbers of global variables, an "enumerate every case I could think of with 25 page if-statements" coding style, vast numbers of unwritten assumptions about the way your processor works. That it works at all, never mind as well as it does, is a testament to the dedication of gcc hackers.

            I think a lot of this is historic, and the newer parts of the compiler are much better (and so the overall code quality is slowly improving as old code gets replaced), but gcc can still be a real pain to work on. If you're trying to port to an architecture that differs in some way from "typical" architectures, be prepared for misery.

      The caching JIT has been available since 3.4, but is disabled by default. To turn it on, you'll need to add these switches to your gij command line:

      -Dgnu.gcj.jit.compiler=/usr/bin/gcj -Dgnu.gcj.jit.cachedir=/tmp -Dgnu.gcj.jit.options=-O2

      In practice, this is not a great help because gij and gcj are so slow. You may be able to get much better results compiling directly from Java source to machine code, and then prelinking the resulting executables and shared objects to reduce startup time.

    Back in the day the first step in loading up a UNIX workstation with Open Source tools, was to go out and grab a limited precompiled version of GCC, then bootstrap compile an more suitable version, then go to town on compiling all the rest of the goodies that we couldn't live without. We did it so often that it became second nature to go through this process.

Also it reduces the confusion and complexity for first-timers.

          Also considering the age of the packages found in all the stage tarballs all of them have been replaced by newer versions so when you install Gentoo you will actually recompile everything from source.

      Please do take this in the supportive spirit in which it is intended. It's a letter from GCC's initial author, Richard Stallman [com.com] (also founder of the free software movement) to a CNet article author who referred to GCC as an "open source" programming tool.

      Quoting from that letter:

      I appreciate the admiration expressed in your article about upgrading the GNU Compiler Collection [gnu.org], but it erred in describing the program as an "open source" programming tool. I developed GCC as part of the Free Software Movement [wikipedia.org]--so that people can use computers in freedom as part of a community.

      Free software means software that respects the users' freedom. The philosophy of the movement is that users of software should be free to run it, study it, change it, redistribute it and publish modified versions.

      With these freedoms, you're free to engage in cooperative development; you're also free to develop it on your own or to redistribute it unchanged. Describing this as a "philosophy of cooperative development" emphasizes one beneficial consequence of freedom at the expense of freedom itself.

      It was impossible in 1984 to use a computer in freedom, since all the operating systems were proprietary. So I launched the development of GNU, a free Unix-like operating system.

      A Unix-like system must include a C compiler, so I wrote one: GCC. I designed it to handle other languages, also, so that GNU users could use more than one. GCC, like the GNU/Linux operating system in which GCC is a crucial part, exists because of the ideals of the Free Software Movement--the ideals that are forgotten when speaking of open source.

      Of course, this is not a letter from RMS to you or directly pertaining to your article. However, I thought that it was worth mentioning in case people want to tell their friends about the new GCC release. It seems that people who frequent /. go to some length to make sure that they describe Linus Torvalds' initial authorship of the Linux kernel in a manner according to his chosen movement. I thought that the same respect should be due to RMS.

      • Free Software is a subset of Open Source Software, so to say that GCC is Open Source is absolutely correct, if perhaps more general than RMS would prefer.

        You would make the butt of jokes anyone who tried to demand that you call Roma tomatoes "Roma Tomatoes" every single time you referred to them instead of referring to them generally as tomatoes.

          The philosophical difference RMS describes is quite clear and RMS points it out quite well. The benefits we get from free software are great, but they shouldn't be celebrated at the expense of celebrating the freedom free software gives us for its own sake. You can't "make that group as broad as you want or as narrow as you want" and still convey the same point. People might not know about software freedom, so it's easy to make that mistake without any malicious intent (as I think was the case here). But to set out to refer to programs like GCC—programs written to make software freedom real—in the name of a movement that was built in part to not mention software freedom is ahistorical.

          Free Software is a subset of Open Source Software, so to say that GCC is Open Source is absolutely correct, if perhaps more general than RMS would prefer.

          First of all, it is true that if one only goes by the definition of open source [opensource.org] then the GNU compiler collection does fulfill all the conditions of that definition. GCC also fulfills the Free software definition [gnu.org]. Since this software package seems to satisfy both we must therefore look at some other facts to see which group this software appropriately belongs to.

          Who started writing it and for what reason?
          Richard Stallman did so that we could have more freedom. Not because he thought it simply had more technical merit to publish the code. So GCC would not exist if it were not for the philosophical base upon which it was started continues to rely on. GCC was not started because of any open source philosophy.

          What about the name of the software package?
          Humm, it appears to have the GNU name right at the beginning. I thus deduce that it is strongly involved with the Free software movement.

          In the GCC mission statement [gnu.org] it says that GCC is not only a Free software project, but more importanly that one of the main goals is Supporting the goals of the GNU project, as defined by the FSF. Not to mention that the copyright of GCC are kept by the Free Software Foundation.

          You can make that group as broad as you want or as narrow as you want, but there is a happy medium where the label is non-offensive and clear to any and all that hear it .

          First of all, when talking about open source software you are referring to all software that fulfills the open source definition. That is just as specific and narrow as Free software and the free software definition.
          Regarding the non-offensive jib. There is absolutely nothing offensive about free software nor is there anything offensive about open source. Although I feel all warm inside whenever I hear about someone spending their lives work in defending and increasing my freedom in a non-violent manner.

          Regarding the clarity of "Free software", that is something which is only a problem in the english speaking world. In most other languages the word for freed(dom) and the word for free(of charge) are different.
          Open source is not quite as clear to a non insider of the computer idustry. Freedom is something generally a lot more meaningful then "open source(code)", since most people have no idea what source code is nor how it can be more open or closed but do have some grasp of the meaning of freedom. Many people have certainly heard of open source in the media and such but infer no real meaning from it, except perhaps that it "makes your computer go faster or something" (this is something which I have heard many people say when asked about what open source means to them). If you were to ask those same people if they cared about their freedom, I think you would get at least a little more intelligible answers. Going too narrow may provide more information but at a loss of understanding to your audience.

          How can you fail to put across your meaning if you are being as specific, lengtly and clear about your explinations as possible?! This is just nonsense.

          RMS is in error here, but not because he thinks that software designated Free Software ought not be referred to as Open Source software, but because he thinks that anyone cares.

      Depends. Did you get an A++ in your graduate-level compiler construction class? Are you willing to spend a couple months (or more) reading through the gcc source code to get an understanding of how all the pieces work. Are you willing to spend a few more months testing your optimizations (mathematically and with source code) to make sure they don't break anything?

      The basics of compilers aren't difficult. 2nd year CS students can understand toy compilers. But gcc isn't a toy compiler, it's a real compiler in the real world dealing with a sometimes crazy language, and even crazier users. If you can write better optimizing code, prove it works, and it doesn't infringe on any patents, submit your code.

In fact, I think all software for the Mac is compiled with GCC 4 and onwards.

    Thanks folks, and happy Thanksgiving.

    I'm not sure what gave the person who submitted the story, or the editor who posted the story, the idea that 4.1 was released, but it isn't. In fact, it was just branched less than a week ago. We haven't even put out an RC yet! Really, it's not out. When it is, you will see something sent to gcc-announce

    • I'm not sure what gave the person who submitted the story, or the editor who posted the story, the idea that 4.1 was released, but it isn't.

      The GCC home page [gnu.org] very clearly states "Current release series: GCC 4.1.0" while below it all the others say "Previous release series" and one at the bottom says "Active development (mainline)." That indicates as clearly as can be which are the old, the current, and the development releases.

      It is surprisingly hard to find out what the current release is from the GCC webpages. The front page has a misleading 4.1. Press "Releases", and you get a misleading 3.4.4. You have to go on to the "Development plan", under Future timeline [gnu.org], to find the actual latest and greatest 4.0.2 somewhere down the ASCII art tree.

    GCC 4.1.0 is not yet out as far as I know. This story is misleading. Just because the site lists 4.1.0 on the front does not mean it is out. Notice that it doesn't have a release date on it.
  • Azureus can now be used in a 100% Free-Software system.

    For those of us who aren't Linux geeks :) what was wrong with Azureus before?
    • Azureus is programmed in Java. Therefore it had to execute under a Java Runtime Environment (JRE) as provided by Sun or IBM. All of these JRE's are not free. Now Azureus can be compiled by GCC (which is free), Azureus can be executed in a 100% free environment.

      • Thanks for the info, I have one more question though - that's just me knowing pretty much nothing about Java. Say I have an existing installation of Azureus and upgrade to GCC 4.1. Does that mean I could scrap my JRE? Or would I have to recompile Azureus to do that?

        • You would need to recompile Azureus using GCC.
        • You may be able to use Azureus as is with gij(gnu intepreter for java) as opposed to natively compiling it with gcj(gnu compiler for java).
          Considering that Azureus pulls down bytecode updates, gij is probably the way to go.

          I've been using gij and gcj for a while in fedora and am very pleased with how its development is coming along.
          That said, I would go scrapping the Sun jre just yet.

          Though I haven't tried this new 4.1 version, I have had some minor issues with gij/gcj and the java apps I'm using and even
      • Do you lose any functionality by compiling Java to machine code? Maybe not with Azureus, but in general don't some of Java's features preclude compiling directly to machine code (as opposed to JVM code)?

        Clearly you could just avoid using those features, but I'm curious if you get "full-featured" Java when using the GCC Java compiler.
      • I'm still not following :(

        You say that JREs are not free, but, as jofi points out below, Sun's JRE seems to be free.

      Hmmm... the textbook I used in the compiler course I took way back in the olden days said that recursive descent compilers were, in general, slower and in general larger than state-based ones.

      Mind you, the book is over 20 years old now.

        According to a lecture I took last year, this has changed in recent years. Now it's much more important to work on a small set of data at a time, since the processors have large caches. The recursive approach helps to keep the data you're working on inside the cache.

        20 years ago nobody had a cache, so it was an imperative to keep your stack size down.

    GCC 4.1 has not been released yet.

    A modified version of Classpath has been included with GCJ since 3.2.

    Azureus may start in GIJ 4.0, but won't work properly because it relies on parts of the Sun JDK which aren't completely implemented yet in GCJ.

    As many have pointed out, GCC 4.1 is actually several months away from release. Slashdot "editors" might want to learn about a concept called "fact checking." I'm disturbed by the amount of GCC bashing in this list. I've never met a perfect compiler, and GCC is far superior to many commercial tools I've used. It provides professional-quality C, C++, Objective-C, Fortran 95 (almost), Java, and Ada compilers for dozens of platforms; the code generation is imprefect, but then again so is most of the code GCC is required to compile! The vile lack of appreciation for GCC simply astounds me -- it is the foundation of Free Software. And it is a fine piece of work that is constantly growing and evolving -- though not as fast as Slashdot's headlines might suggest... ;)
