Q37901: "Duplicate Definition" LINKing C Graphics Library to BASIC, /O
Article: Q37901 Product(s): See article Version(s): 6.00 6.00b 7.00 | 6.00 6.00b 7.00 Operating System(s): MS-DOS | OS/2 Keyword(s): ENDUSER | S_C S_QuickC B_QuickBas SR# G881109-6007 | mspl13_basic Last Modified: 27-JUL-1990 The C graphics library, GRAPHICS.LIB, is incompatible with programs compiled with BC /O in QuickBASIC versions 4.00, 4.00b, and 4.50, Microsoft BASIC Compiler versions 6.00 or 6.00b, or Microsoft BASIC Professional Development System (PDS) version 7.00. The FONT and CHART graphics in QuickC version 2.00 are also incompatible with programs compiled with BC /O in these versions of QuickBASIC and BASIC compiler. Many of the C graphics routines conflict with the BASIC graphic routines in the BASIC stand-alone library. If you need to do graphics when you link BASIC stand-alone programs with C, the graphics should be done in BASIC. An alternative is to compile without the BC /O option in BASIC. Linking BASIC programs compiled BC /O with Microsoft C graphics routines gives many "Duplicate Definition" errors, even if you LINK with the /NOE option. Compile without /O to eliminate the errors.
