I tried building Ada from a bootstrap binary found on the net. HP-UX 11.23 unlike 11.00 and 11i, doesn't allow executing code on the stack by default. To enable this for individual binaries: $ chatr +es enable [binary]
To enable execution of code on the stack system-wide, the executable_stack kernel tunable needs to be 1 or 2. The default is 0 (disallow execution). While building 4.0.2, I encountered the following: ... stage1/xgcc -Bstage1/ -B/opt/TWWfsw/gcc402/hppa2.0-hp-hpux11.23/bin/ -c -g -O2 -mdisable-indexing -gnatpg -gnata -I- -I. -Iada -I/opt/build/gcc-4.0.2/gcc/ada /opt/build/gcc-4.0.2/gcc/ada/ada.ads -o ada/ada.o Execution of code located on a program's stack is not permitted. cmd: stage1/gnat1 -I- -I. -Iada -I/opt/build/gcc-4.0.2/gcc/ada -quiet -dumpbase ada.ads -O2 -g -mdisable-indexing -gnatpg -gnata -gn PID 24258 has been terminated.
