Dear Guile developers, I recently added support for your great guile library to the mingw-cross-env project. In order to make this work, I had to perform some portability fixes.
I originally created the fixes for the latest stable version (guile 1.8.7), but I ported them forward to your current development version. See the attached patches. (generated with "git format-patch origin/master..HEAD") Note that this doesn't solve all issues. I wasn't able to forward-port my corrections to libguile/__scm.h regarding win32 cross compiling of a _static_ libguile. Well, I could provide something, but I'm unable to test it, because I'm stuck with another problem introduced in 1.9.x: The "gen-scmconfig" script includes a mix of native and cross headers, which goes horribly wrong when performing win32 cross compiling. Is it really necessary to #include the "uniconv.h" from the cross system and to provide corresponding SCM_ICONVEH_* constants? Another note, regarding my patch for the "pthread_att_get_stack" check: I assumed that when in doubt (i.e. when cross-compiling), it is safe to set "works=no". However, I'm not sure about that. Maybe this feature is so common that one should assume "works=yes" when cross-compiling. Greets, Volker -- Volker Grabsch ---<<(())>>--- Administrator NotJustHosting GbR
