Hello, Sometimes, I use the i386-elf-gcc (GCC 3.2.1) from the public ecoscentric toolchain for I386 to build/debug some test using the eCos synth target.
AFAIK, they don't recommend to use native GCC for that. The synth.ld script (hal/synth/arch/current/src/synth.ld) contains a point #if (__GNUC__ >= 3) GROUP(libtarget.a libgcc.a libsupc++.a libgcc_eh.a) #else GROUP(libtarget.a libgcc.a) #endif According a ChangeLog, that was Jonathan Larmour's tweak. But their GCC 3.2.1 has no libgcc_eh.a at all: ~/ecos/gnutools/i386-elf/i386-elf/lib/libcygmon.a ~/ecos/gnutools/i386-elf/i386-elf/lib/libsupc++.a ~/ecos/gnutools/i386-elf/i386-elf/lib/libstdc++.a ~/ecos/gnutools/i386-elf/i386-elf/lib/libnosys.a ~/ecos/gnutools/i386-elf/lib/gcc-lib/i386-elf/3.2.1/libgcc.a So, I have to fix the GROUP description in the result ld script (install/lib/target.ld) every time to build the test, i.e. to replace the line GROUP(libtarget.a libgcc.a libsupc++.a libgcc_eh.a) by GROUP(libtarget.a libgcc.a libsupc++.a libgcc.a) Well, that isn't an issue for the sed, but... Question: Do we need to change that condition in the synth.ld to check the GCC minor version to fix the problem? Does somebody mess that too? The GCC spec is Reading specs from /home/sg/ecos/gnutools/i386-elf/bin/../lib/gcc-lib/i386-elf/3.2.1/specs Configured with: /home/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/x86_linux_lsb1_3/tar_bz2/source/gcc-3.2.1/configure --target=i386-elf --prefix=/home/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/x86_linux_lsb1_3/tar_bz2/opt/ecos/gnutools/i386-elf --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib --with-gxx-include-dir=/home/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/x86_linux_lsb1_3/tar_bz2/opt/ecos/gnutools/i386-elf/i386-elf/include Thread model: single gcc version 3.2.1 The ecosconfig version is ecosconfig 2.0 (May 9 2003 09:45:47) Copyright (c) 2002 Red Hat, Inc. My usual steps to build any test are 1. Build libtarget.a ecosconfig new linux <template> ecosconfig tree make -s ECOS_COMMAND_PREFIX=i386-elf- 2. Fix `install/lib/target.ld' (as it was described above) 3. Make the test Thanks. -- Sergei -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
