It seems to work. Although when I start make test on real win32 system
after doing make on linux system, it complains about "certificate
rehashing skipped, openssl program not available". I've tried with 0.9.8
I'd repeat this with current development tree.

First of all, nm program name should be overriden to, but openssl
Makefile.shared do not define variable for nm, and hardcodes program
name instead. Now make complains about "file format not recognized"
Second problem with cross build is that make does certificate
rehash, using freshly compiled c_rehash program. It doesn't lead to make
failure, but it would be nice to be able to redefine c_rehash as well,
and use one from host system OpenSSL during build stage (of course, for
If people are interesting, I can publish somewhere results of nightly
build on our test farm. Now we have following platforms
1. Various Linux distributions
2. FreeBSD 4.x, 5.x and 6.x on i386, FreeBSD 6.x on AMD 64
3. Solaris x86 8, 9 and 10
4. Solaris Sparc 10 (both 32-bit and 64-bit build)
5. Mingw build on Win32 system using Cygwin compiler and ActiveState Perl.
We can add build with real mingw compiler on Win32 and linux-hosted build with

It is applicable at least to real mingw. I don't remember exact
circumstances, but when we've switched from 0.9.8a to 0.9.8b we have
problems with deploying mingw32 build (which is used in production
environment now) and problem was solved by using proper .def files.
It is applicable for both native and linux-hosted builds (although we
never tested mingw build with cygwin compiler in production
environment). It was related to changes in DSO_WIN32 (which began to
find engine modules correctly in this release).
