I am working with the Asterisk application, it uses "modules" these are .so files which are linked against the main executable. Asterisk will load a module, which may or may not make use of code exported by the main executable. Is this two way DLL allowed under windows?

This is the last one that I remember, and it was just a few weeks ago: http://cygwin.com/ml/cygwin/2005-09/msg00875.html Yes, it's possible. But there are some drawbacks.

A better solution would be to put all Asterisk code into a shared libray besides Asterisk main() and link asterisk.exe and the modules against this libray. You know that there is a project which already has ported asterisk to Cygwin: http://www.asteriskwin32.com/ ?

If I understand you correctly, then it's not so difficult; I've done it myself with bmp, gedit, gthumb, liferea, and xmms. I don't know Asterisk, but it doesn't appear to use autotools; this makes things more difficult, especially if you want to make a portable patch. First, make sure that the asterisk executable is built *first*; you may need to precede '.' to the SUBDIRS variable (i.e. SUBDIRS = . subdir1 subdir2 etc.) Add the following to the asterisk executable's LDFLAGS: '-Wl,--export-all-symbols,--out-implib,libasterisk.dll.a' Then, add the following to all the modules LDFLAGS, specifying the correct location: '-Wl,/path/to/libasterisk.dll.a'. Of course, make sure that all requisite link libraries are specified in LIBS for both the executable and the modules. You'll still need to find some way of making all this dependent on Cygwin in the Makefiles in order to make this portable.
