Hello Richard and Alexei Thank you for your kind reply.

You're right, the code is ELF-specific because of dlopen and friends. I don't see what makes it glibc-specific, though. But then, the entire code is pretty much disabled to throwing stubs #if !defined(HAVE_LIBDL).

Tatsuru, can you, please send us your config.log file?

(The patch was failed. I attached it as a zipped file. The file is too large for the ML. I delete it. To Richard and Alexei, I personally attach it. The cygwin tools was used to the path setting from the mingw. export PATH=$PATH:/c/Programs/cygwin/bin:/c/Programs/cygwin/usr/X11R6/bin So ginac.pc at PKG_CONFIG_PATH seemed not to work correctly. Instead export CLN_CFLAGS='-I/usr/local/octave-3.0.0/include' export CLN_LIBS='-L/usr/local/octave-3.0.0/lib' export GINAC_CFLAGS='-I/usr/local/octave-3.0.0/include' export GINAC_LIBS='-L/usr/local/octave-3.0.0/lib' seemed to work. I tried pkg-config.exe 0.18.?? (>0.9.0) from the Gimp tool kit but it did not works at all. So I tried pkg-config.exe on the cygwin. The problem I think the mktemp is not installed to the mingw nor the msys. I found 'mktemp-1.5-MSYS-src.tar.bz2'. I'll try it from now.
