How to cross compile Openssl 1.1.0 for Windows Host on Ubuntu 14.04 LTS
@DaniAffCH
Once the compile is done and there are no errors, , do a make install. The resulting files should be in /usr/lib/x86_64-w64-mingw32
Afterwards, the compiler should be able to use the libs and include files by default.
Use -L/usr/lib/x86_64-w64-mingw32 if you are getting linker errors though it might indicate a faulty installation.
Note if you want 32-bit binaries you need to set the target to mingw and change to the i686 compiler. In other words: ./Configure --cross-compile-prefix=i686-w64-mingw32- mingw
./Configure mingw shared --cross-compile-prefix=x86_64-w64-mingw32- --prefix=${WORKSPACE}
