I'm attempting to use crosstool 0.28-rc37 to build a host=fedora core 2, target=i686-unknown-linux-gnu toolchain - for the purposes of building an x86 target image, using a toolchain divorced from the build system. (Note: I'm aware that e.g. LFS uses a much more complex process than simply building a cross-compiler, so as to divorce itself completely from the host. I'm assuming that since crosstool forces a build of a cross-compiler, it's equivalent. Still, I guess the built toolchain still relies on the host system glibc and hence could be affected by bugs there at runtime, but that's no worse than if I were building cross to any other target I think?) Anyway, I need NPTL support for my target. So, I attempted to apply contrib/crosstool-0.28-rc34-nptl_fixes.patch. I ignored the errors to all the config files (*.dat and related), manually fixed the reject to getandpatch.sh, built my own config files and attempted to build. My config files are: nvidia-build-i686.sh ============================ #!/bin/sh set -ex TARBALLS_DIR=/home/swarren/src/tar RESULT_TOP=/home/swarren/crosstool-nptl export TARBALLS_DIR RESULT_TOP GCC_LANGUAGES="c,c++" export GCC_LANGUAGES GLIBC_ADDON_NPTL=1 export GLIBC_ADDON_NPTL mkdir -p $RESULT_TOP eval `cat nvidia-i686.dat nvidia-gcc-3.4.3-glibc-2.3.3.dat` sh all.sh --notest ============================ nvidia-i686.dat ============================ TARGET=i686-unknown-linux-gnu TARGET_CFLAGS="-O" ============================ nvidia-gcc-3.4.3-glibc-2.3.3.dat ============================ BINUTILS_DIR=binutils-2.15 GCC_DIR=gcc-3.4.3 GLIBC_DIR=glibc-2.3.3 LINUX_DIR=linux-2.6.9 ============================ When I run this, I get an error about undefined symbols _Unwind_Resume and __gcc_personality_v0: ... i686-unknown-linux-gnu-gcc -nostdlib -nostartfiles -static -o /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/ gcc-3.4.3-glibc-2.3.3/build -glibc/elf/sln /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/ gcc-3.4.3-glibc-2.3.3/build-glibc/csu/crt1.o /home/swarren/src/crosstool- 0.28-rc37-nptl/build/i686-unknown-linux-gnu/gcc-3.4.3-glibc-2.3.3/build- glibc/csu/crti.o `i686-unknown-linux-gnu-gcc --print-file-name=crtbegin.o` /home/swarren/ src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/gcc-3.4.3-glib c-2.3.3/build-glibc/elf/sln.o /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unkno wn-linux-gnu/gcc-3.4.3-glibc-2.3.3/build-glibc/libc.a -lgcc /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/ gcc-3.4.3-glibc-2.3.3/build-gl ibc/libc.a `i686-unknown-linux-gnu-gcc --print-file-name=crtend.o` /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/ gcc-3.4.3-glibc-2.3.3/ build-glibc/csu/crtn.o /home/swarren/src/crosstool-0.28-rc37-nptl/build/i686-unknown-linux-gnu/ gcc-3.4.3-glibc-2.3.3/build-glibc/libc.a(iofclose.o)(.text+0xd3): In function `fclose': : undefined reference to `_Unwind_Resume' ...

I notice that the error is building the "sln" executable. Somebody previously on this list mentioned this problem, I think for a MIPS NPTL toolchain, but I think they ignored the error, since they could build the kernel with the new toolchain which was all they wanted (but they why did they want NPTL in that case - perhaps I misremember?) I'd like to actually get the resultant GLIBC installed so I can use it for building user-space code, so I can't just ignore this error! If/when I get this working, I'd be quite happy to rediff the contrib NPTL script against rc37 so it applies cleanly - I'd probably split it up into a separate core patch, and one that does all the .dat files etc. Thanks for any help. -- Stephen Warren, Software Engineer, NVIDIA, Fort Collins, CO swarren@nvidia.com http://www.nvidia.com/ swarren@wwwdotorg.org http://www.wwwdotorg.org/pgp.html ------ Want more information?
