Now I've managed to cross-compile current CVS tree with
Mingw32 crosscompiler both in static and shared version.
Following changes are needed to the source tree:
1. Configure
1.1. Add -Wl,--export-all to the shared library linker command line
1.2. Add -lws2_32 to list of libraries to link IPV6 stuff (not
compatible with old versions of windows, but my MingW32 runtime
doesn't have libwship6.a). I've found that on our test Win2000
system WINNT/System32 folder contains ws2_32.dll which was brought
by some service pack
1.3. Remove setting of IsMK1MF variable to 1 in case of mingw build
(as suggested by Andy Polyakov above in the thread)
2. Makefile.shared
Define NM variable to hold name of nm program (which also differs
from just nm when cross-compiling)
Replace explicit call to nm by reference to this variable.
3. ssl/ssl_sess.c
Move #include "ssl_locl.h" above
#include <openssl/rand.h>
because ssl_locl.h includes e_os.h, which includes winsock2 and
ws2tcp.h, and rand.h includes windows.h, which includes winsock.h if
winsock2.h wasn't previously included
4. crypto/bio/b_sock.c
add #include "e_os.h" to provide neccessary definitions for IPV6
stuff
5. engines/ccgost/gost_eng.c
Remove __declspec(dllexport) before IMPLEMENT_DYNAMIC_CHECK_FN
and IMPLEMENT_DYNAMIC_BIND_FN macros. These macros now include
OPENSSL_EXPORT which expands to appropriate declspec under Win32.
