I guess I have to put the path to the library libgrx20X.a instead of "GRX"?

Nope. It must be "GRX" here.

`libgrx20X.a' is linked either with a directive

{$L libgrx20X}

(may be already present in `grx.pas') or explicitly on the command line:

gpc --automake -o fgraphs fgraphs.pas -lgrx20X -lX11

That is to say /usr/local/lib. But where and how?

If the path is not known to the compiler, use the `-L' option:

gpc --automake -o fgraphs fgraphs.pas -L /usr/local/lib -lgrx20X -lX11

(But if the library is in /usr/local/lib, it should be found without the `-L'.)

Hope this helps,

Peter
