Hi Victor,

Unfortunately each way creates *.a files with different names */ Configure+make creates - libcrypto.dll.a - libcrypto.a - libssl.dll.a - libssl.a */ mingw32.bat creates - libeay32.a (= libcrypto.dll.a) - libcrypto.a - libssl32.a (= libssl.dll.a) - libssl.a On top of that you have also MS compiler (cl/msvc) in MS Windows world which uses also different library names: libeay32*.lib ssleay32*.lib (from here probably comes "-lssleay32 -llibeay32" which should be fine with MS compiler) Things get a little bit more complicated by the fact that the more-or-less official openssl Win32 binaries distribution (see http://www.openssl.org/related/binaries.html) contains also mingw/gcc *.a libraries - however named: libeay32.a + ssleay32.a (which does not correspond to the results produced by the mingw.bat from official openssl tarball). Please note that ssleay32.a is not libssleay32.a thus linker will not find it when given -lssleay32 - this is IMHO the main source of confusion about the right lib names. What we have done in strawberry was to use naming convention libeay32.a/libssl32.a + a little trick to copy libssl32.a to libssleay32.a - at that time it seemed to be a way how to satisfy most of the modules on cpan using different -lssleay32/-lssl32/-leay32 linker options I do not feel to have an authority to say what is the best/right/correct way but I would keep the naming convention of the original openssl distribution and use: -lssl32 -leay32 for MSWindows+gcc compiler (which works with openssl included in strawberry perl however not with *.a mingw libraries that are part of the openssl Win32 binaries distribution). -- kmx
