Greetings, I'm trying to build gcc on an AIX 5.2 box which I don't have administrative rights to. There are two versions of gcc already installed: 3.2 in /usr/local/bin and 3.3 in /usr/local/gnu/bin. However, when I try to build things with MPI (using the -mpe switch), using either gcc I get linker warnings and the code segfaults. I've also tried the binary at http://aixpdslib.seas.ucla.edu/packages/gcc.html but it is built for AIX 5.1 and gives the same errors. I also tried the binary for AIX 5.2 at http://www.bullfreeware.com/ but it seems to require root to install. So I am trying to build my own version of gcc, since IBM's compiler has caused me problems in the past. Whenever I try building gcc with either installed version of gcc, I get internal compiler errors. So I've been trying to use IBM's compilers. However, if I run /tmp/work/wlandry/gcc-3.3.4/configure --enable-languages=c,c++ --enable-threads=aix --prefix=/tmp/work/wlandry/gcc-bin /usr/local/bin/gmake bootstrap then I get an error involving md5.h and conflicting symbols. It turns out that the compiler (cc) is looking in /usr/local/include for some reason, and there is an md5.h there. I've managed to get past that by putting md5.h and md5.c in the same directory and compiling it manually. However, I then get similar errors involving /usr/include/errno.h being included by libiberty/strerror.c. It is again confused by conflicting symbols. If I manually work through this error the same way as before, I get a similar error later on. And another if I continue. And another. Then I gave up. This happens whether I'm using gcc 3.3.4 or 3.4.1. So my question is, is my setup so broken that I'm just hosed? The required APAR fixes have been installed, I'm using gmake, and I'm configuring with absolute pathnames. The only success report for AIX on the buildstat page was building from an older version of gcc, and they had to play around with some standard includes. Has anyone been able to build it with IBM's compiler? Thanks, Walter Landry wlandry@xxxxxxxx
