Hubris and ignorance, I guess :) Anyway! Thanks to your input and after following your advice and stuff in last comment from here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47907 (but there was no need to substitute SITE_CONFIG variable, creating config.site and copying it to "${DIR_PREFIX}/share/" was enough) I were able to obtain a working C compiler. Yay. Now I'm going to check how to run test suite with resulting compiler, any help will be appreciated. If all goes well, adding fix from this bug report to gcc sources would be great. Sources used were: gcc from svn, revision 183510 (future 4.7.0, I guess), binutils 2.22, mpc 0.8.2, mpfr 2.4.2 and gmp 4.3.2. Winning configure commands were: ../../src/binutils-2.22/configure --prefix="${DIR_PREFIX}" \ --target=rs6000-ibm-aix4.3 \ --with-sysroot="${DIR_SYSROOT}" ../../src/gcc-$VERSION/configure \ --prefix="${DIR_PREFIX}" \ --enable-static \ --disable-multilib \ --disable-nls \ --disable-shared \ --with-sysroot="${DIR_SYSROOT}" \ --with-gnu-as \ --with-gnu-ld \ --enable-languages=${LANGS} \ --target=rs6000-ibm-aix4.3 \ --with-cpu=powerpc with variables set to: DIR_PREFIX=/opt/xgcc-aix-4.3.0.0-47_c LANGS=c and DIR_SYSROOT pointing to sysroot. Switch "--with-cpu=powerpc" was added, as otherwise build system targets some other architecture - I'm not sure which. Unfortunately, libstdc++ still fails to built with error: gmake[4]: Entering directory `/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include' mkdir -p ./rs6000-ibm-aix4.3/bits/stdc++.h.gch /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/xgcc -shared-libgcc -B/root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc -nostdinc++ -L/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/src -L/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/src/.libs -B/opt/xgcc-aix-4.3.0.0-4.7.0_c_cxx/rs6000-ibm-aix4.3/bin/ -B/opt/xgcc-aix-4.3.0.0-4.7.0_c_cxx/rs6000-ibm-aix4.3/lib/ -isystem /opt/xgcc-aix-4.3.0.0-4.7.0_c_cxx/rs6000-ibm-aix4.3/include -isystem /opt/xgcc-aix-4.3.0.0-4.7.0_c_cxx/rs6000-ibm-aix4.3/sys-include -x c++-header -nostdinc++ -g -O2 -I/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/rs6000-ibm-aix4.3 -I/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include -I/root/xcomp/src/gcc-4.7.0/libstdc++-v3/libsupc++ -O2 -g -std=gnu++0x /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h \ -o rs6000-ibm-aix4.3/bits/stdc++.h.gch/O2ggnu++0x.gch In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/bits/atomic_base.h:37:0, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/atomic:41, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:100: /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include/stdint.h:72:29: error: conflicting declaration 'typedef short int int_fast16_t' In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/sys/types.h:64:0, from /root/xcomp/src/sysroot//usr/include/sys/lc_core.h:36, from /root/xcomp/src/sysroot//usr/include/sys/localedef.h:43, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/ctype.h:131, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/cctype:44, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:36: /root/xcomp/src/sysroot//usr/include/sys/inttypes.h:143:18: error: 'int_fast16_t' has a previous declaration as 'typedef int32_t int_fast16_t' In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/bits/atomic_base.h:37:0, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/atomic:41, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:100: /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include/stdint.h:75:29: error: conflicting declaration 'typedef unsigned char uint_fast8_t' In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/sys/types.h:64:0, from /root/xcomp/src/sysroot//usr/include/sys/lc_core.h:36, from /root/xcomp/src/sysroot//usr/include/sys/localedef.h:43, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/ctype.h:131, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/cctype:44, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:36: /root/xcomp/src/sysroot//usr/include/sys/inttypes.h:145:18: error: 'uint_fast8_t' has a previous declaration as 'typedef uint32_t uint_fast8_t' In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/bits/atomic_base.h:37:0, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/atomic:41, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:100: /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include/stdint.h:76:30: error: conflicting declaration 'typedef short unsigned int uint_fast16_t' In file included from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/sys/types.h:64:0, from /root/xcomp/src/sysroot//usr/include/sys/lc_core.h:36, from /root/xcomp/src/sysroot//usr/include/sys/localedef.h:43, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/./gcc/include-fixed/ctype.h:131, from /root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include/cctype:44, from /root/xcomp/src/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:36: /root/xcomp/src/sysroot//usr/include/sys/inttypes.h:146:18: error: 'uint_fast16_t' has a previous declaration as 'typedef uint32_t uint_fast16_t' gmake[4]: *** [rs6000-ibm-aix4.3/bits/stdc++.h.gch/O2ggnu++0x.gch] Error 1 gmake[4]: Leaving directory `/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3/include' gmake[3]: *** [all-recursive] Error 1 gmake[3]: Leaving directory `/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3' gmake[2]: *** [all] Error 2 gmake[2]: Leaving directory `/root/xcomp/build/gcc-build-4.7.0_c_cxx/rs6000-ibm-aix4.3/libstdc++-v3' gmake[1]: *** [all-target-libstdc++-v3] Error 2 gmake[1]: Leaving directory `/root/xcomp/build/gcc-build-4.7.0_c_cxx' gmake: *** [all] Error 2 Which is (almost?) identical to my previous report. You wrote in your other post that I should check file "/root/xcomp/build/gcc-trunk-20120123/./gcc/include/stdint.h", which now became "/root/xcomp/build/gcc-build-47_c/./gcc/include/stdint.h". It doesn't contain any preambles similar to yours. There are no "include" directives, only a lot of defines and typedefs. -- Jędrzej Dudkiewicz I really hate this damn machine, I wish that they would sell it. It never does just what I want, but only what I tell it.
