StringUtils, FileUtils
by Frank Heckenbach 31 May '02

Hi, in the current GPC version, I've included a StringUtils unit for general string handling routines (on a higher level than the built-in and RTS routines). Up to now, it only contains routines for a string hash table, but I'm planning to add some more routines. Perhaps some of you also have some routines to contribute (or features to request). Conditions for inclusion into this unit should be, IMHO: - Generally useful (not meant specifically for a certain program or something), - self-contained (not relying on an external library etc.), - new functionality compared to the existing routines (whereas the same or similar functionality under a different interface for compatibility purposes should go into other units, like GPCUtil for compatibility to `Turbo Power' units), - and, of course, compilable with the current GPC version, portable, bug-free, etc. ;-) The same goes for the FileUtils unit which has been there for some months already.

If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc.

operators pow and **
by Maurice Lombardi 01 Feb '02

Hi all, It seems that operators pow and ** cannot be redefined in gpc. Is that expected ? I work with djgpp / w98 dos box (should be irrelevant I think) Thanks Maurice -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: 33 (0)4 76 51 47 51 Fax: 33 (0)4 76 51 45 44 mailto:Maurice.Lombardi@ujf-grenoble.fr

install gpc on AIX 4.3.3
by Paul Tedaldi 10 Feb '01

10 Feb '01

Hi, installation of gpc-20010111 on AIX 4.3.3 had the following problems: - while linking gpc1 the TOC overflows: ld: d: 0711-781 ERROR: TOC overflow. TOC size: 67732 Maximum size: 65536 The problem can be circumvented by adding the "-Wl,'-bbigtoc'" flag to LDFLAG (assuming gcc is used to call ld, for xlc it's just "-bbigtoc") It strikes me as odd that all other gcc compilers (gcc, g++, f77, objective c and java do not overflow the TOC during install. - while compiling the RTS with xgpc, rts/internal.pas produces invalid assembler code. rts/internal.pas contains procedure RunFinalizers (var AtExitProcs : PProcList); asmname 'gpc$runfinaliz ers'; The AIX assembler does not allow "$" in symbols ! After changing "gpc$runfinalizers" to "_p_runfinalizers" the RTS could be built. Of course the magic name is now destroyed. Is it possible to fix the above problems in the distribution so that GPC can be installed on AIX in a standard manner ?

Pascal GNU Compiler for Solaris 8 ?
by br＠is.informatik.uni-kiel.de 30 Jan '01

30 Jan '01

Hello, I'm not used to Sun Solaris but I need to work with an Ultra10 for my new projects. Can somebody give me a short reply about: Does the Pascal GNU Compiler work with Solaris 8 ? I saw some 'extra binaries' on a polish website and all other releases only for Solaris 2.x or 7. Thanks Bernd -- Bernd Rehling Institut fuer Informatik Christian-Albrechts-Universitaet Kiel

[Fwd: Re: memset]
by George Shapovalov 29 Jan '01

In Borland Pascal you would use fillchar(var x;value:word [size:word]); so the invoking would look exactly like your example: fillchar(x,0,sizeOf(x)); However with BP you can do it to the <64K in size variables (as this is a maximal size for "regular" variable in BP). Does this work for gpc as well?

Is there a fast way to zero a large array, e.g. an equivalent to the following C fragment? int x[100,100]; memset(x, 0, sizeof(x)); -- Steve

Stack problems?
by Steve Loft 26 Jan '01

26 Jan '01

I'm using gpc 20010115 on a Linux system. I'm having problems with a program I've written which has recursive function calls, which I thought may be down to blowing the stack. If I run the program in gdb, when it crashes I can't get it to display a backtrace: Program received signal SIGSEGV, Segmentation fault. 0x240804e7 in ?? () (gdb) bt #0 0x240804e7 in ?? () Cannot access memory at address 0xbabffff5 So I compiled it with --stack-checking, and now it crashes much earlier, with a segmentation fault on a 'var' statement. It's at about 20 levels of recursion, and the function only uses three of four integers of local variables; uname -s tells me I have 8196k of stack, so I'm puzzled as to why I'm blowing the stack, if indeed I am. Is a SIGSEGV what you would expect to see as a result of turning on stack checking? Are there any known problems in gpc in this area? Any suggestions as to what I can do to investigate further?

Hello , I need a good manual to help me convert the Intel syntax into AT&T syntax. I had a look at : ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/contrib/gpcasm.zip Though it is mentioned that i can have more information in http://www.dcs.warwick.ac.uk/~jules/nasm1.html and http://www.tu-chemnitz.de/~rho/rhide.html I am not able to get the right link because there are some missing letters in the link. can you kindly let me know the complete site? Thank you Regards, Anu
