I did a check locally, the wrong OBJECT_MODE caused the assembler error like Assembler: /tmp//ccZmd28O.s: line 1: 1252-192 Assembly mode is not specified. Set the OBJECT_MODE environment variable to 32 or 64 or use the -a32 or -a64 option. Hope it's just a pasted typo, isn't responsible for this error. > # export LDFLAGS="-L/opt/freeware/lib64 -L/opt/freeware/lib -maix64 > -Wl,-b64 -Wl,-brtl -Wl,-bbigtoc > -Wl,-blibpath:/opt/freeware/lib64:/opt/freeware/lib:/usr/lib:/lib" > > This is my configure line: > > # /usr/src/gcc-10.2.0/configure --with-isl=/usr/local --disable-multilib > --disable-nls --enable-languages=c,c++ --enable-decimal-float=dpd > --with-cloog=no --with-ppl=no --disable-libstdcxx-pch > --enable-__cxa_atexit --disable-werror --enable-bootstrap > With David's help, I built gcc trunk on aix7.2 successfully before with the configuration command like: $GCC_SRC/configure --enable-languages=c,c++,fortran --disable-werror --with-gmp=/opt/freeware/ --with-libiconv-prefix=/opt/freeware/ --disable-libstdcxx-pch --with-included-gettext --with-cpu=power9 --prefix=$GCC_INSTALL --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-bootstrap I referred to the information here https://gcc.gnu.org/wiki/CompileFarm "Building GCC on AIX" Also installed the required components pointed out here: https://gcc.gnu.org/install/prerequisites.html via the website/repo aix-toolbox https://www.ibm.com/support/pages/aix-toolbox-linux-applications-downloads-alpha Sorry that I didn't have the access to that machine any more, can't provide more information by checking the history. > And this is the end of make where it dies: > > [ -f stage_final ] || echo stage3 > stage_final > make[1]: Entering directory '/usr/src/gcc-build' > make[2]: Entering directory '/usr/src/gcc-build' > make[3]: Entering directory '/usr/src/gcc-build' > rm -f stage_current > make[3]: Leaving directory '/usr/src/gcc-build' > make[2]: Leaving directory '/usr/src/gcc-build' > make[2]: Entering directory '/usr/src/gcc-build' > Configuring stage 1 in ./intl > configure: loading cache ./config.cache > checking for powerpc-ibm-aix7.2.4.0-gcc... gcc > checking whether the C compiler works... no > configure: error: in `/usr/src/gcc-build/intl': > configure: error: C compiler cannot create executables It would be good to see what's the specific error.
