Good Morning, I am trying to install gcc for a HP-UX 10.20 system. I have /usr/local/objects=objdir and /var/tmp/gcc-2.95.2=srcdir. The configuration portion of the installation works. But when I try to build gcc using 'make bootstrap', I get the following error (with line of code it's hanging up on): cd /var/tmp/gcc-2.95.2/gcc/java && $bison -t --name-prefix=java_ \ -o parse.c ./parse.y sh(2): bison: not found *** Error exit code 127 Stop *** Error exit code 1 Stop *** Error exit code 1 Stop *** Error exit code 1 Stop. Do you know what I need to do to keep this from happening? Thanks in advance for your assistance! Best Regards, Molly Cartwright
