If not that then I honestly have no idea what the issue is, I'll attatch my codeblocks project files in case it has something to do with that, for the actual code that's already uploaded to http://code.google.com/p/zxstuff/source/ - files of interest are dll.h, stdc.h, compiler.h, sys.h, vector/*.h On 14 November 2013 20:48, Ian Lance Taylor <iant@xxxxxxxxxx> wrote: > > On Thu, Nov 14, 2013 at 10:50 AM, awsdert <gb2985@xxxxxxxxx> wrote: > > Thank you, unfortunately it does not solve the problem I originally posted > > which is: > > > >>include\zx\window\..\std\vector\dec_fun.h|19|note: #pragma message: > > ZX__INIT( zxVECTOR, void, __attribute__((dllexport)), )| > > > > is the output I get, > > > > include\zx\window\..\std\vector\dec_fun.h|19|note: #pragma message: > > ZX__INIT( zxVECTOR, void, __attribute__((dllexport)), zxVECTOR__init)| > > > > is the output I expect, > > > > #define ZXV___INIT( NAME, T, DLL, FUN ) DLL void \ > > FUN( NAME *src, T const *cpy, size_t count ) > > #define ZXV__INIT( NAME, T, DLL, CALL ) \ > > ZXV___INIT( NAME, T, DLL, CALL NAME##__init ) > > > > is the code I'm using. > > Am I doing something wrong here or is GCC?
