has anyone managed this with success? i can built ada programs just fine with "gnatmake file.adb" when the gnat 3.15p binary distribution is at the end of my $PATH, but i cannot build gcc-4.0 after a configure --enable-languages=ada with it at the end of my $PATH i am trying to use gcc-3.3.4 to build gcc-4.0, rather than the ancient version of gcc that ships with gnat (so, putting the gnat dir in my $PATH first doesn't seem to be an option since the gcc binary there will overshadow /usr/local/bin/gcc which is otherwise first in my $PATH). i have no ada support in my gcc-3.3.4 build but would like it in my 4.0.0 build. below is the error during the 'make bootstrap': make[2]: Entering directory `/v/filer3/v1q010/fool/Work/build/lin_gcc/gcc' gcc -c -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -gnatpg -gnata -I- -I. -Iada -I/u/fool/Work/build/gcc-4.0.0/gcc/ada /u/fool/Work/build/gcc-4.0.0/gcc/ada/ada.ads -o ada/ada.o gcc: /u/fool/Work/build/gcc-4.0.0/gcc/ada/ada.ads: Ada compiler not installed on this system make[2]: *** [ada/ada.o] Error 1 make[2]: Leaving directory `/v/filer3/v1q010/fool/Work/build/lin_gcc/gcc' make[1]: *** [stage1_build] Error 2 make[1]: Leaving directory `/v/filer3/v1q010/fool/Work/build/lin_gcc/gcc' make: *** [bootstrap] Error 2 i use debian stable and a self-built gcc-3.3.4 which works well otherwise. will gcc-4.0.0 build with gcc-2.8.1? (what ships with gnat-3.15p, the latest binary distribution i could find...) thanks in advance for any advice!
