* Why does the OpenSSL compilation fail on Alpha True64 Unix?
On some Alpha installations running True64 Unix and Compaq C, the compilation
of crypto/sha/sha_dgst.c fails with the message 'Fatal: Insufficient virtual
memory to continue compilation.' It's currently unknown why this happens,
except that it has to do with optimization. The very quick solution would
be to compile everything with -O0 as optimization level, but that's not a very
nice thing to do for those who expect to get the best result from OpenSSL.
A bit more complicated solution is the following:
----- snip:start -----
make DIRS=crypto SDIRS=sha "`grep '^CFLAG=' Makefile.ssl | \
sed -e 's/ -O[0-9] / -O0 /'`"
rm `ls crypto/*.o crypto/sha/*.o | grep -v 'sha_dgst\.o'`
make
----- snip:end -----
This will only compile sha_dgst.c with -O0, the rest with the optimization
level chosen by the configuration process. When the above is done, do the
test and installation and you're set.
