No need to build x32 GCC. Just enable x32 run-time in x86-64 GCC with -with-multilib-list=m32,m64,mx32 is sufficient. > (I guess --disable-gcj was probably useless now) > > But when I configure the same way from the head (from two days ago), it > fails on stage2: > > /home/daniel/proj/sys/gcc/unpatched/configure > --prefix=/home/daniel/local/gcc-unpatched --build=x86_64-pc-linux-gnux32 > --with-abi=mx32 --enable-checking=yes,rtl --enable-languages=all > --enable-bootstrap --enable-option-checking --enable-lto > --enable-gold=yes --with-system-zlib --enable-link-mutex > --enable-libgomp --enable-targets=all --disable-gcj x32 GCC built fine on trunk on Aug. 10 with configure --with-demangler-in-ld --enable-languages=c,c++,fortran,lto,objc,obj-c++,go --prefix=/usr/gcc-8.0.0-mx32 --with-local-prefix=/usr/local --enable-gnu-indirect-function --enable-clocale=gnu --with-system-zlib --enable-libmpx --with-multilib-list=m32,m64,mx32 --enable-linker-build-id --enable-gnu-unique-object --with-abi=mx32 --with-fpmath=sse checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu I didn't use --build=x86_64-pc-linux-gnux32 -- H.J.
