Hi, I'm building a Perl extension (dll in Windows XP) using ExtUtils::MakeMaker. This dll needs to link with other libraries that were built in static mode (-MTd). My perl configuration states dynamic libraries (-MD) which causes MakeMaker to pull a dynamic C library (msvcrtd.dll). The other libraries are using the static C library (libcmtd.lib) These dynamic and static C libraries collide giving link errors. Is there a way to force perl to compile with (-MTd) albeit its configuration flags?
