Hi everbody,
I'm a newbie in the gnu project an I hope someone can help me.
I download yesterday GCC 2.95,2 and I tried to compile the gcc
on UnixWare 7.0.1 on an Intel Pentium II with the command
make boottrap . I got the error message undefined symbol
alloca in the file genattr.o
Has someone an idea how I can fix the problrm.
best regards
Andreas Walter

2.95.2 does bootstrap successfully on UnixWare 7. The alloca problem
you describe is often a symptom of starting a bootstrap, aborting it for
whatever reason, then restarting it. (GCC's bootstrap gets confused
about which compiler to use in this case.) Is that a possibility in
your case?
A "sure fire" approach to solving this is to use
CC="/bin/cc -O -Kalloca" /path/to/configure ; make bootstrap
The version of SCO's CC (with C99 support to be released Any Day Now)
automatically turns on -Kalloca when not generating code for strict ISO
conformance.
