I have gotten gcc 3.4.1 & glibc 2.3.2 & linux 2.4.18 / 2.6 to cross for mipsel.
The problem we are seeing is in the dynamic linking. Static linking to glibc works fine, dynamic crashes with a null pointer. Has anyone else seen this problem?
I haven't seen this exact problem, but I did bring up a toolchain on sh4, and I had similar problems. I ended up debugging them in two ways: 1) by running the glibc and gcc regression tests (see crosstest-howto), and 2) by starting with a working target environment from some other source (e.g. montavista), and creating a chroot jail containing my new environment. I then inserted print statements (well, write syscalls) into glibc etc. until I tracked down the problem.
I poked around a bit, and found some posts that might be related: http://sources.redhat.com/bugzilla/show_bug.cgi?id=660
FYI: I am going to put together a patch for the 2.4.18 kernel for it to work with 3.4.1. There were some minor changes to a few files.
Any chance one of the errors was arch/mips/kernel/time.c:278: error: unknown register name `accum' in `asm' That's what stops linux-2.6.8; see http://kegel.com/crosstool/current/buildlogs/mipsel-gcc-3.4.3-glibc-2.3.2.log.txt ?
Thanks! - Dan
