I doubt it. As far as I can see from your config.log, the header and library paths are Cygwinish. So, the compiler sees <dlfcn.h> header (which is *NIX- and Cygwin-specific), the linker picks (cygwinish) libdl and libreadline, and the build gets messed up. Fortunately, you get a compile error instead of misterious run-time failure[s].

export PATH=$PATH:/c/Programs/cygwin/bin:/c/Programs/cygwin/usr/X11R6/bin

Unfortunately, that's not enough. You should set at least CPPFLAGS and LDFLAGS to prevent the linker and compiler from using cygwin-specific stuff. You might also need to append -mno-cygwin to CFLAGS and CXXFLAGS.

So ginac.pc at PKG_CONFIG_PATH seemed not to work correctly.

Please post the actual error message, along with config.log from that particular attempt.

Instead export CLN_CFLAGS='-I/usr/local/octave-3.0.0/include' export CLN_LIBS='-L/usr/local/octave-3.0.0/lib'

I wonder how this could ever work. At least, you should add -lcln to CLN_LIBS. Depending on how CLN was configured, you might also add -lgmp.

export GINAC_CFLAGS='-I/usr/local/octave-3.0.0/include' export GINAC_LIBS='-L/usr/local/octave-3.0.0/lib'

The build scripts do not use these variables (they are harmless, but not necessary).

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.

"Does not work at all" is not really informative. Please post the actual error message.

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 don't think so. That package contains the `mktemp' utility, which simply calls corresponding function from the C runtime library. It is necessary for some (UNIX) shell scripts. GiNaC does not use that utility. As far as I understand, your problem is completely different. The code in excompiler.cpp is platform-specific and should not be built on window$ (it won't work there anyway). The configure should have disabled it, but it did not, because your build environment (in particular library and headers search paths) is misconfigured. I suggest to use MinGW/msys tools instead of mixing MinGW and Cygwin (unless you are experienced Cygwin/UNIX user). If you encounter some problems, please post error message(s) (along with config.log file) here. Best regards, Alexei -- All science is either physics or stamp collecting.
