--- Comment #80 from EML <elowe at elowe dot com> --- Starting from the top: I have applied my patch in comment 63 I have applied dave's patch in comment 72 I have applied #undef MAKE_DECL_ONE_ONLY patch My configure line is: ../gcc-8.3.0/configure --prefix=/usr/local/gcc8.3 --with-as=/usr/local/bin/as --without-gnu-ld --disable-nls --disable-libgomp --disable-libgcj --enable-shared --enable-threads=posix --with-gnu-as --with-ld=/usr/ccs/bin/ld --enable-languages=c,c++ My Make line is: make STAGE1_CFLAGS="-O0 -g -D_XOPEN_SOURCE_EXTENDED" STAGE1_CXXFLAGS="-O0 -g -D_XOPEN_SOURCE_EXTENDED" CFLAGS_FOR_TARGET="-O0 -g -D_XOPEN_SOURCE_EXTENDED" STAGE1_TFLAGS="-O0 -g -D_XOPEN_SOURCE_EXTENDED" BOOT_CFLAGS="-D_XOPEN_SOURCE_EXTENDED" My "system" compiler is GCC 4.9.3: Target: ia64-hp-hpux11.31 Configured with: ../gcc-4.9.3/configure --without-gnu-ld --with-ld=/usr/ccs/bin/ld --disable-nls --disable-libgcj --enable-shared --enable-threads=posix --disable-libgomp --enable-languages=c,c++ SED=/usr/local/bin/sed AWK=/usr/local/bin/gawk LDFLAGS=-lunwind AS=/usr/local/bin/as Thread model: posix gcc version 4.9.3 (GCC) During stage0 - MPFR will ICE in GCC4.9.3 due to TLS. You need to go into the MPFR directory and re-run the same configure line from config.log, but add --disable-thread-safe. The stage1 compiler will now build. Woot managed to build some version of gcc 8.3 During stage1 - MPFR will ICE in the stage1 xgcc also due to TLS. Again you need to --disable-thread-safe for MPFR (making sure to set CC correctly) The stage2 compiler will now build - hey it managed to build itself. The stage2 compiler will ICE while building ../../../../gcc-8.3.0/libstdc++-v3/libsupc++/array_type_info.cc well that was unexpected, since it did build itself once, but it failed apparently while building stage3.
