With merely "external" the compiler uses the C variant of the identifier for the platform which on Win32 contains a "_" at the start (for Win64 for example there is none). "external <NAME>" is used to tell the compiler to look for the C identifier ("_HelloC" on Win32, "HelloC" on Win64) inside the library "HelloC.dll". To look for "HelloC" in a statically linked object file or library you need to use "external name <NAME>".ok. I backed up to a simple version. how I declare the C routine must be the problem, with nothing, procedure HelloC; cdecl; external;I think it's trying to static link it, and gets an pcode.pas(19,1) Error: Undefined symbol: _HelloC with anything else procedure HelloC; cdecl; external 'HelloC'; it links, but dynamically and then the routine is never found.
This is on an evil windows machine
Windows is one of FPC's main targets, we can do without such "expletives". Regards, Sven _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
