Re: using C routines in pascal

Hello, Thankyou for the response. whe i link the library file, it gives me the following errors. $ gpc -L/usr/local/psql/lib -lbtrvif -DBTI_DEC_UNIX sqlnew2.pas reqsamp1.o: In function `__btrid': reqsamp1.o(.text+0x5e): undefined reference to `Handler' collect2: ld returned 1 exit status $ But a C program compiled like this works well. Can you tell me what the reason could be?

2 small problems with compiler
by Sven Sahle 27 Nov '00

27 Nov '00

Hi, I use "gpc version 19991030, based on 2.95.2 19991024 (release)" on an Intel-Linux computer (suse 7.0) and have encountered the following problems: 1. When I accidentally have a pascal source code with a uses-statement that includes a unit with the name of the sourcecode file itself I get an endless loop when compiling it with --automake or --autobild. The compiler uses all memory available. example: A file called "test.pas" containing "uses test;" statement. 2. When I upgraded to the above mentioned version of the compiler I got an "Internal compiler error: program gpc1 got fatal signal 11" when I compiled without --autobuild and had old gpi- and object-files around. A more descriptive error message would be nice.

using C routines in pascal
by Nathalie Jarosz 27 Nov '00

27 Nov '00

Hello all, Is someone could help me about using C routines in pascal? I think I am close to the right solution but I can't manage to get it!... So I will try to summurize all I made until now... At first, I have downloaded randlibc-1.3.tar.gz. After having unpacked this file, a randlib.c directory was created and it contains: HOWTOGET* README* doc/ src/ test/ In src, I have compiled com.c, linpack.c and randlib.c and put them in a library lirandlib.a Then, I have move librandlib.a into /usr/local/lib and randlib.h in /usr/local/include. Actually, I would like to use a fonction named "genbet" in the randlib.c. For that, I have made a little program beta.pas: unit beta; interface {$L /usr/local/include/randlib.h} function genbet(x,y:shortreal):shortreal;C; implementation end. and test.pas: uses beta; begin writeln(genbet(100,150)); end. When I compile the first one, the following message appears: Undefined first referenced symbol in file main /usr/local/lib/gcc-lib/sparc-sun-solaris2.7/ 2.95.2/crt1.o ld: fatal: Symbol referencing errors. No output written to beta collect2: ld returned 1 exit status And for the second one: test.p:4: object file `/usr/local/include/randlib.o' not found test.p:4: object file `/usr/local/include/randlib.o' not found "extern float genbet(float aa,float bb)" is in randlib.h and the program is written in randlib.c. I really need your help, Nathalie ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Memory use problem
by Martin Liddle 24 Nov '00

24 Nov '00

This is not a bug report but just a heads up to see if anybody else has seen a similar problem. Some of our gpc programs are what I would term as server processes. By that I mean that they are intended to run in the background for several days at a time serving requests that are passed to them in various ways. We have recently realised that these programs are steadily increasing their memory usage with cpu time used such that the system, in the worst case, runs out of swap space. The problem may well be in our own code but we have not yet isolated it. I just wondered if there was any other possible explanation eg something in the run time system or whether anybody else had seen similar problems? Any advice on strategies for isolating the problem would also be appreciated. -- Martin Liddle, Tynemouth Computer Services, 27 Garforth Close, Cramlington, Northumberland, England, NE23 6EW.

keywords of gpc
by Thorsten Hindermann 22 Nov '00

22 Nov '00

Hi! I have a special question to Frank and/or Peter: can you tell me a place (in the Web or in the gpc-sources) where I can find all supported keywords of gpc. The best way are they sorted to any supported dialect by gpc (e.g. UCSD,Borland,ISO7186 ...). I need this information for the pindent project. Thanx Thorsten

RH7.0
by Marius Onica 19 Nov '00

19 Nov '00

Hi everybody, What about using gpc under RH7.0 . As I've read gpc is working with gcc 2.95, but under RH7.0 I have gcc 2.96. Now what to do ? I've tried to compile gcc 2.95+gpc but it failed so I don't know what to do. Any suggestion is welcomed! TIA, Marius

Hi! I'm trying to cast a Function to a procedure, but my little program fails with a "Segmentation fault". Could anyone please tell me, what is wrong? 8<------- (snip) ---------------- Program TestIt; Type bar = Procedure(a:Integer); Var BarFunc : bar; Function FooFunc(a:Integer) : Integer; Begin Writeln('I am of foo with:', a); FooFunc := a+1 End; Begin Writeln('FooFunc(3) is ', FooFunc(3)); Writeln('now bar(FooFunc(2))'); BarFunc := bar(FooFunc(2)); BarFunc(2) End. ------- (snap) ---------------->8 Thank you Eike
