In MSVC you have the
pragma to tell the linker to include that library. Does gcc have anything similar, or is the -l command line switch the only way?Code:#pragma comment(lib, "library-name")

The "-l" switch is portable while the pragma directive is not, so why bother.
How is "-l" any more portable? It's just as gcc specific as that pragma is microsoft specific.
And yes, using directx libraries in a discussion about portability might seem stupidCode:C:\src\cpp>cl 1.cpp -ld3d9 Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.21003.01 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. cl : Command line warning D9002 : ignoring unknown option '-ld3d9' 1.cpp Microsoft (R) Incremental Linker Version 10.00.21003.01 Copyright (C) Microsoft Corporation.

Guess I work only on the ones that have a CLI and the "-l' switch is common to all of 'em.
Okey, if it can't be done then it can't be done. No big deal, I normally compile under cygwin if I need to make sure my code is portable.
I was just curious if you could do something like
but I guess not.Code:#if defined(MSVC) #pragma ...etc #elif defined(GCC) #includelib .. #endif
Yep! you can with gcc; no clue about MSVC. gcc has a predefined macro __GNUC__ that can be evaluated during the preprocessor phase likeOriginally Posted by _Mike
Code:#ifdef __GNUC__ #<gcc specific pragma> #elif <MSVC predefined macro, if any> #<MSVC specific pragma> #endif
