Allegro CL 4.1 Foreign Loading: Problem and Solution
Dear Allegro CL Users:
Due to an outdated solution to a problem that no longer even exists,
Allegro CL 4.1 users may occasionally run into a failure while
attempting foreign file loading. The symptoms are a foreign load
failure preceeded by the following messages:
; Foreign loading [....]
ld: /lib/libc.a(_unpack_dble.o): __unpack_quadruple: multiply defined
/lib/libc.a(_sprintf_sup.o): __prod_b10000: multiply defined
/lib/libc.a(_sprintf_sup.o): __carry_out_b10000: multiply defined
/lib/libc.a(_sprintf_sup.o): __prod_65536_b10000: multiply defined
Warning: Foreign load failed
The fix for this is simple, but requires rebuilding Allegro CL. You
do not need to read in the distribution tape if you have the
distribution directory online. All you need to do is the following:
% cd <allegro-dist-directory>/build/
% /bin/mv removesyms removesyms.orig
% /bin/cp /dev/null removesyms
After this, you can rebuild your lisp in the normal way via the config
script ("sh config").
If you can't rebuild your lisp, then a short term solution is to do
the following before attempting a foreign load:
(dolist (s '("__prod_b10000" "__carry_out_b10000"
