[LLVMdev] Can't Bootstrap llvm-gcc4.2 on Ubuntu 11.04 32-bit
I can't bootstrap llvm-gcc4.2 on Ubuntu 11.04 32-bit. It's not a test failure; instead the configure scripts break in all kinds of mysterious yet spectacular ways. I spent a couple days beating my head against those completely indecipherable shell scripts then gave up for now. Is there a buildbot that runs Ubuntu 11.04? If not may I suggest that one be set up? A minimal Ubuntu installation could be run in a VM and need not use much disk space. I do realize that I don't need to bootstrap on Ubuntu, but that I could use the llvm-gcc that is provided by the Ubuntu maintainers. The reason that I'm bootstrapping the hard way is that I want to learn how to do it myself, so that later I can bootstrap on Haiku. Haiku (http://www.haiku-os.org/) is an Open Source clone of BeOS 5. It has two ABIs, with two sets of runtime libraries, one built with GCC 2.95.3 for compatibility with existing BeOS executables, and the other built with a current GCC for new code. Haiku is almost entirely written in C++, and is a HUGE codebase. I'd like to set up the CLang static analyzer to analyze the whole works. Besides being a good test of the analyzer, and likely to uncover new opportunities for analysis, lots of Haiku's coders are C++ newbies, so I expect our existing analyses will uncover a multitude of sins.

If I don't get some sleep RIGHT NOW my head is going to explode. However, it's been over a week since I did an "svn update". I'll do that first then re-try the bootstrap. If I understand correctly, the gcc upon which we build our llvm-gcc builds itself in two phases. First it builds itself using whatever compiler it finds installed on the build platform, then it builds itself again with the compiler produced in the first pass. The errors are produced in the configure scripts from the second pass. That's what makes them especially hard to debug.> Is there a buildbot that runs Ubuntu 11.04?

I have a Xen VM web server with some decent filesystem space, CPU speed and memory. I'll set up the buildslave in a VirtualBox VM on my laptop, then once it is decently configured, I'll transfer it over to my server. I really, really gotta go to sleep right now. I won't sleep through the night though because I am to have supper with my mother and her twin sister. After I get back from supper, I'll deal with it then. If it's not to hard to set up the buildslave, I'll set one up for Ubuntu 11.10 as well. The "10" in the version number means October, if I understand correctly, so it's supposed to be released soon.
