I downloaded nrpas from ftp://garbo.uwasa.fi/pc/turbopas/nrpas13.zip and it seems to contain beta distribution.

OK, I got it thru. Look like -I/usr/X11R6/include pointed to no where on my box.

Hello all! I just wonder if it is possible to plot some graphs with pascal? If the answer is yes, how it works? And if not, how can I use my output files to easily generate graphs? Thanks for your help, Nathalie

Hello all again! Another question. I have some numerical recipies for pascal downloaded from a website but I don't have the program for a beta distribution. Is someone got it? thanks a lot in advance, Nathalie

Problem with last patch of grx23
by Maurice Lombardi 21 Jun '00

21 Jun '00

http://www.gnu.de/software/GRX/grx23.update.000520.gz 1 - it is not gzipped 2 - four hunks failed (with respect to the original grx23.zip, no update) in highlow.h grdriver.h makebase.dj and makefile.bcc two (in makebase.dj and makefile.bcc) contain "return return linefeed" instead of "return linefeed" as end of lines dtou solves that the other are cosmetic changes (some extra spaces to align consecutive lines) which seem different between your version of "original" grx23 and the one on simtelnet. The best is probably to make fresh new diffs rather than to try to modify the present diff file. 3 - more seriously, compiling tests on grx23 fails at the first file (arctest.c) for not finding GrLine. The problem seems that the src/bgi/line.c coming from bcc2grx (which is merged now) shadows in the merged library libgrx20.a the src/draw/line.c which comes from the original grx23 (and which contains the function GrLine() ). This was not a problem with the old setup where compiling with -lbcc2 -lgrx20 (for bcc2grx) or simply -lgrx20 for pure grx solved the problem. In fact looking to the output of the "ar -rv" command in the make command I see that indeed bgi/line.o is replaced (flagged r) instead of to be added (a). And the same is true for polygon.o fillpatt.o and fillpoly.o according to the same listing. Since the problem is with the filenames, not with the functions which they contain (the systematic prefix Gr in libgrx avoids that), I have renamed these four files (in src/bgi) as lineb.c polygonb.c fillpatb.c and fillpolb.c and modified accordingly src/stdobjs.mak. All compiles without problem now. All tests run perfectly except for one in bccbgi: the sierpinski test (i.e. the first floodfill test), while the snake test (the second floodfill) works. In looking to floodfill() contained in src/bgi/fldfill.c I see that you have changed the content of that function with respect to old BCC2GRX to call directly grx functions. If I restore the old content by replacing at the beginning of the floodfill() function: #if (GRX_VERSION_API-0)>=0x0225 by #if 0 everything works perfectly. I have not tried to understand further. 4 - A directory grx23/chr containing the .chr files (which are presently in src/bgi) should be included in order that the character tests work (or replace the BGI_PATH in the tests programs, but creating a chr directory analogous to the font directory seems better). 5 - I have tried the pascal tests. They work except for two problems which were already presents in previous versions of grx and bgi2grx. - pascal/bgi/demos/color.pas fails due to an invalid typecast between real and word. Replacing word() by a function realtoword() which rounds the real corrects it. - the polygon tests (DrawPoly and FillPoly) in pascal/bgi/demos/demo.pas fail due to a problem when transferring "open arrays" parameters between pascal and C for recent alphas of gpc. gpc pushes in that case an extra parameter on the stack so that "var Polypoints: array of PointType" in pascal is no more equivalent to "PointType *Polypoints" in C, because C pushes only the address of Polypoints. The trick is to use in the pascal unit an untyped variable "var Polypoints" which pushes also only the address of Polypoints on the stack. With this correction the demo program works perfectly. It is necessary to change that way pascal/bgi/bgi2grx.pas and also pascal/grx20.pas (I have no test program at hand to check in that case however).

Debugging GPC compiled code with GDB
by Pierre Muller 16 Jun '00

16 Jun '00

I got the djgpp binary distribution of GPC and made some tests with my pascal aware GDB. But if I compile a simple program (similar to hello word ) and a start GDB and insert a breakpoint at main (which is what allmost vevery body would do in C, and that works as expected with Free Pascal compiled code) If I then use "run" the program stops at the end of the main code, which is rather odd! If this a known problem and is it or will it be fixed. The source code used follows I wanted to test the internal form of string to see if I could support it ! program test_gpc(input,output); type string32 = string[32]; var s1, s2 : string32; begin s1:='It '; s2:=s1+'works'; Writeln('It works'); Writeln(s2); end.

> the program stops at the end of the main code, which is rather odd! Whoops, it seems that this was due to a problem of wrong linker or gcc version recompiling from djgpp bin dir gives something a little bit better : the main break works and the program is indeed stopped before the main procedure but nevertheless main has no line info and thus "next" command will go right to the end ! Couldn't the startup code be integerate at begin of the main code directly ? This way "next command would stop at the begin of the line s1:='It'; > program test_gpc(input,output); >type > string32 = string[32]; >var >s1, s2 : string32; >begin > s1:='It '; > s2:=s1+'works'; > Writeln('It works'); > Writeln(s2); >end.
