Thanks Eljay, By extension, if I stick to ansi C, can I mix gcc compiled libraries: . with any other major compilers ? (e.g. gcc with Borland) . on all major platforms ? (e.g. gcc with unix vendor's native compilers) Do the answers apply equally to object files (.o, .obj) and shared/dynamic libraries (.dll, .so) ? e.g. can I replace a .so created with Sun's compiler on solaris with a gcc generated .so ? Do the answers follow from some kind of formal ansi C compliance contract (would appreciate a URL) or lack thereof ? Finally, here is the context of my questions: . My clients: . Applications - C/C++ . Platforms - Windows, Linux, IRIX, Solaris, hp-ux, AIX ... . Development environments - MSVS, gcc, etc.. (native compilers) . Me'self: . Algorithms - C (some Java, hope to use gcj) . Deliverables - plug-in libraries . Development environment - prefer GCC solely yours newbie-ly, -Anup -----Original Message----- From: Eljay Love-Jensen [mailto:eljay@xxxxxxxxx] Sent: Monday, April 12, 2004 4:50 AM To: anup_s@xxxxxxxxxx; gcc-help@xxxxxxxxxxx Subject: Re: library created with gcc acceptable in MS VC++ application ? Hi Anup, Presume you are using a C interface, yes, you can use a GCC DLL with MSVC executable. Or vice versa. If you are using a C++ interface, my first guess is that GCC's C++ ABI is different from MSVC's C++ ABI. I'd be shocked if they worked together. --Eljay
