Re: [gentoo-user] How do I use LLVM?

If that fixes it, you should file a bug against the specific package failing to build, noting the missing explicit build dependency. After some testing, and plain old trial-and-error, I discovered that it may have been due to me running with USE starting with -*. I found out that... * emergeing llvm does not help * I unmerged llvm, and added the line media-libs/mesa llvm to /etc/portage/package.use, and the build works. Now that I know what to look for, I can find... https://bugs.gentoo.org/show_bug.cgi?id=377013 which covers this issue. The problem is that the generic error message... configure: error: LLVM is required to build Gallium R300 on x86 and x86_64 ...is not informative enough. This has been fixed in mesa 7.12, due out in a few months. Apparently, it'll generate an error message advising that mesa must be built with USE=llvm if Gallium R300 is to be built. -- Walter Dnes waltd...@waltdnes.org

As I mentioned in my reply to Michael Mol, building mesa with the llvm USE flag does the trick. It appears the web pages http://www.gentoo.org/doc/en/xorg-config.xml and http://www.gentoo.org/doc/en/ati-faq.xml may be out of date. The video card shows up under lspci as... ATI Technologies Inc RV280 [Radeon 9200 PRO]. According to the Gentoo web pages, it doesn't need a firmware blob at all. However, when booting, the PC said something about loading an R200 blob. It sat there for a minute, timed out, and went on to a standard VGA display. I emerged radeon-ucode and it came up with 62 files, including R200_cp.bin. I stuck that file into the [*] Include in-kernel firmware blobs in kernel binary option in the kernel, rebuilt, and it appears to work. Since this is an actual gentoo.org webpage, and not a wiki, I'll file a documentation bug at bugs.gentoo.org. The torture test will come this evening. I'm a paying subscriber to NHL Gamecenter Live. What prompted me to do all this work in the first place was the fact that the onboard Intel GPU couldn't quite keep up to a live hockey game in fullscreen mode. There was occasional stuttering of the video. I went to all this trouble in hopes of a better viewing experience. BTW, I have 2 Dell Dimension 530's. On the one with only the onboard GPU, glxgears shows just over 60 fps. On the one with the ATI card it's jumped to over 262 fps. Last minute note. DRM is *NOT* in effect. I'll be starting a separate thread on that. It's an excellent adventure in its own right. -- Walter Dnes waltd...@waltdnes.org
[gentoo-user] How do I use LLVM?
And no, it's not because I'm adventurous. Background... I'm trying to revive an older Dell Dimension 530 (32 bit install) with a Radeon card that uses a binary blob from the radeon-ucode ebuild/download. When trying to emerge xorg-server, it fails with the message... configure: error: LLVM is required to build Gallium R300 on x86 and x86_64 I understand that LLVM is a gcc-like compiler. What is the minimum amount of stuff that I need to do? Are there any LLVM-compatability libraries for gcc that would do this build? -- Walter Dnes waltd...@waltdnes.org
