Re: Building on Windows from scratch - guile problem SOLVED
Well, interestingly enough, the problem is not directly with the compiler optimizer. It's with the configure test for strncasecmp. This test fails on mingw in its current incarnation because guile uses a standard test for the function, but on mingw strncasecmp is actually a cpp definition. As a result, guile is compiled with #HAVE_STRNCASECMP unset, and so guile tries to create its own version in read.c Now if you compile with no optimization, the compiler notices that read.c is attempting to create this with a different signature and bombs out. However, with optimisation on, the code compiles for some reason, and then fails to run properly. So there seem to be two problems: one in configure for guile and/or the standard configure macros on mingw, the other in the compiler. Fortunately, there's a very easy although ugly workaround, which is to add an echo "#define HAVE_STRNCASECMP" >>config.h in install-impl.sh just after the guile configure and before the make I've incorporated this fix into my downloadable file of fixes as referred to on the wiki page I updated. More as and when I find any further issues. As always, feedback or other experiences welcome.
