The bug might be provoked by a combination of two procedures, so this effort wasn't in vain. If the shortest code that still fails is not very long (I suppose it isn't if most of the implementation was removed -- and probably much of the interface can be removed as well), you might want to show it to us so we can have a look at it and try to fix the problem. > Try using the latest gcc as a base?

Probably not. Units generally work better than (or at least as well as) modules in GPC.

You never have to compile files one at a time by hand. After having unpacked the sources called randlibc-1.3.tar.gz, I have the folder randlib.c composed of 2 text files and 3 folders named doc, src and test. In the src folder, there are 4 files : com.c, linpack.c, randlib.c and randlib.h but no makefile?... ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

I realize that maybe I have to do something with randlib because I don't have either lrandlib or librandlib.a... Do you know how to use this Randlib? ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

So, I would like to use a beta random deviates I have in C, in my pascal program. I have downloaded "randlib" which contain this function. In randlib.h, there is: extern float genbet(float aa, float bb); First, I have written beta.p : unit beta; interface function genbet(x,y:real);C; implementation end. Second, test.p: program betadev; uses beta; begin writeln(genbet(100,150)); end. Finally, I compile it with gpc and the following message appears: "undefined first referenced symbol in file genbet /var/tmp/cciCa09s1.o ld: fatal: symbol referencing errors No output written to test collect2 : ld returned 1 exit status" So... What is wrong? Thanks in advance, Nathalie ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
