Hello, I have been running the cffi's test suite on my oldish pentium 4 for a while now and all is fine with it; but now I decided to port my software to an amd64 Athlon X2 and the test suite of cffi blows up trying to build libtest32.so. Here is what it prints out: ------------------------------------------ ; loading system definition from ; /home/Jean-Claude/.libs/systems/trivial-features.asd into ; #<ASDF1 package> ; registering #<SYSTEM TRIVIAL-FEATURES 34643616> as TRIVIAL-FEATURES gcc -m32 -o libtest32.so -shared -Wall -std=c99 -pedantic -g -fPIC libtest.c In file included from /usr/include/features.h:376, from /usr/include/stdio.h:28, from libtest.c:34: /usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory make: *** [libtest32.so] Error 1 Debugger called in: #<process SI:INITIAL 00000000010b4d20>. erred while invoking #<ASDF:COMPILE-OP (:VERBOSE NIL) 34714464> on #<CFFI-TESTS-SYSTEM::C-TEST-LIB "libtest" "cffi-tests" 34716192> --------------------------------------------------------------------- This is under Fedora 11 by the way. What purpose does libtest32.so serve if there is a libtest.so? Can I simply cut out all this "32" library thing? Thanks, Jean-Claude Beaudoin
