MacOS X 10.7.5 Lion. MacPro 4,1Intel dual CPU quad cores. I've been away for a while so haven't worked on this. Back now and picking up the thread.
The bug is 13342 (see also 10015 and 10681) triggered by running make check > bad return from expression `(f-sum -1 2000 -30000 40000000000)': expected > 39999971999; got 39999972255 > FAIL: test-ffi There are 2 compilers available from Apple for C/C++ i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00) Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn) I've built a standalone test with both of these compilers and they seem not to be the problem Using the configure/make/make install is routine. But I am not familiar with the details of the make system. I built guile-2.0.7 using the default configure/make and have 2 questions: (a) How can I find out which compiler/linker combo is used? (b) How can I change configure.ac to use the other one? (If that's the right place to make the change) Thanks… Peter
