--- Comment #17 from TCH <tch at protonmail dot com> --- Okay, GCC6 now compiles and the resulting compiler can compile too. So, this is the right way to do: untxz gcc-6.5.0.tar.xz cd gcc-6.5.0 patch -p0 < ../gcc6_solaris10.patch cd .. mkdir gcc6 cd gcc6 export LD_LIBRARY_PATH="$LD_LIBRARY_PATH"':/opt/csw/lib/' ../gcc-6.5.0/configure --prefix=/opt/gcc6 --build=sparc-sun-solaris2.10 --with-gnu-as --with-as=/usr/local/bin/as --enable-shared --disable-nls --enable-languages=c,c++,objc --with-gmp=/opt/csw --with-mpfr=/opt/csw --with-mpc=/opt/csw make make install And then, when using the compiler: export LD_LIBRARY_PATH="$LD_LIBRARY_PATH"':/opt/csw/lib/' export PATH='/opt/gcc6/bin:'"$PATH" gcc whatever.c It may be better, if the exporting lines are put into '.profile'. Thanks again for the help.
