Hi. I'm trying to build mingw-w64-gnutls 3.6.12 on Archlinux. At some point it wants to make a C++ dll out of a C convenience static library and a C++ object file, but libtool omits the static library and link fails with undefined reference. I don't understand why libtool omits the static library, because if I call g++ directly the dll is created just fine. I had to manually add `-lssp` to the command line, but I'm not sure if that's the cause.
Libtool assumes that static libraries do not contain objects which are built appropriately for use in shared libraries or DLLs. Quite often objects need to be built in special ways (e.g -fPIC, dllexport/dllimport declarations) in order to work in shared libraries.
