grx2.4 and mingw32

For simplicity I wrote a short program..

For compiling with fortran I have to compile it as follows:

gcc -c test.c g77 -o test test.o -lgrx20 -mwindows

I need g77 for linking with FORTRAN code requiring the FORTRAN libraries..

test does do nice things (no window for the graphics context..)

The MAIN__ (required as PROGRAM xxx for the fortran library) and GRXMain seem to be fighting against each other..

-- test.c -- #include <grx20.h> #include <malloc.h> static int xmax, ymax, status;

int MAIN__() { GRXMain(); }

int GRXMain() { gstest1(); }

gstest1() { long nplanes; int points[4][2] = {{30,30},{300,30},{300,300},{30,300}}; GrLineOption GSDefinition;

/* Initialisiere Graphik */ GrSetMode(GR_default_graphics); xmax=GrMaxX(); ymax=GrMaxY();

/* Initialisiere eine Farbe (Rot) */ GrSetColor( 2, 255, 0, 0);

/* Zeichne Viereck mit Groesse des Bildschirms -10 */ GrBox(10, 10, xmax-10, ymax-10, 2);

GrSetMode(GR_default_text);

}

Any idea? Gerhard Schneider
