GrCreateContext

If GrCreateContext(); is mallocing the memory space and malloc fails, does the returned GrContext variable == NULL or what else would indicate a failure? Cheers Richard

Hi all! Thanks Anja for the grx.pas... >From: Anja Drewitz <anja(a)maeh.theo-phys.uni-essen.de> >To: "Nathalie Jarosz" <jarosz_n(a)hotmail.com> >Subject: Re: grx-2.3.1 >Date: Mon, 10 Jul 2000 19:09:38 +0200 >If you write "include GRX;" as in >Peter's example it must have the name "grx.pas", I think. In grx-2.3.1/include, I have something named "grx20.h"?... So, I have put grx.pas where I want to compile fgraph.pas but, it still not working... gpc --automake -o fgraph fgraph.p -lgrx20X -lX11 fgraph.p:37: module/unit interface `Grx' could not be imported When I compiled grx.pas, I have grx.o and grx20.gpi. So, I tried to renamed grx20.gpi in grx.gpi and now the message is: gpc --automake -o fgraph fgraph.p -lgrx20X -lX11 ld: fatal: library -llibgrx20X: not found ld: fatal: File processing errors. No output written to fgraph collect2: ld returned 1 exit status Thanks for your help, Nathalie ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Is it normal that the message says:"ld: fatal: library -llibgrx20X: not found" instead of "-libgrx20X"?...

Hello all! >From: Peter Gerwinski <peter(a)gerwinski.de> >To: grx(a)gnu.de >Subject: Re: grx-2.3.1 >Date: Fri, 7 Jul 2000 17:48:37 +0200 >Program fGraphs; > >uses > GRX; (* Portable Graphics library *) > I guess I have to put the path to the library libgrx20X.a instead of "GRX"? That is to say /usr/local/lib. But where and how?

Hello all! So, I think the installation is more or less ok now. The running of the test programs seems to work. But, now, I have no idea of how to do to generate some graphs from data files?... Is there a grx documentation which explain how to use it?

What have you done ? I suspect you have >unpacked grx-2.3 instead of >grx-2.3.1 Maybe you are right... I have downloaded grx-2.3.1.tar.gz again but I can't manage to unpack it. I type tar xvf grx-2.3.1.tar.gz (Unix) and the following message appears: tar: directory checksum error . What is the problem?
