StringUtils, FileUtils
by Frank Heckenbach 31 May '02

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. You're using which OS? Groetjes, Berend (-: fido: 2:281/527.23 email: berend(a)beard.nest.nl

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

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

bug?
by Adam Naumowicz 23 Nov '01

23 Nov '01

Hello, Maybe that is a known bug but I encountered a strange problem and don't know what happens. I reduced the example to these three silly files: --------------------- program tester; uses tester1; begin ImpSgnList.Init(8); end. ---------------------- unit tester1; interface uses tester2; var ImpSgnList:MList; implementation end. ---------------------- unit tester2; interface type MList = object constructor Init(ALimit: Integer); end; implementation constructor MList.Init(aLimit: Integer); begin end; end. ---------------------- The result of execution is as follows: tester.dpr: In main program: tester.dpr:5: Internal compiler error in `call_method', at objects.c:137 Please submit a full bug report to the GPC mailing list <gpc(a)gnu.de>. See <URL:http://home.pages.de/~GNU-Pascal/todo.html> for details. I use the following compiler version: Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.3/specs gpc version 20010623, based on 2.95.3 20010315 (release) BTW: the same is with my another GPC version: Reading specs from /usr/local/lib/gcc-lib/i386-pc-solaris2.8/2.95.2/specs gpc version 20010121, based on 2.95.2 19991024 (release) I hope there is an explanation of this behavior, or if this is a new bug, there will be a way to correct it.

Problem with preprocessor conditionals
by Sven Jauring 02 Oct '01

02 Oct '01

Hi all I'm having problem with preprocessor conditionals containing comparisions, eg. "#if X == 4". After the following code has executed, the variable var1 is set to 10,not 15 as I expected. --------------------------- #define X 4 #define Y 1 . . . var1 := 0; #ifdef Y var1 := 10; #endif #if X == 4 var1 := 15; #endif ---------------------------- Should this work as I expect? Best Regards Sven Jauring

Memory leak
by Miklos Cserzo 28 Sep '01

28 Sep '01

Folks, there is a serious memory leak in the gpc-20010623. The full story: The gpc version on the SuSE 7.2 CD is broken. The installation from source is smooth. The results of the test codes are excellent only 8 fails. Then comes the problem. I wrote a code. It compiles and starts to run. But after a few minutes crashes out with segmentation fault. The "top" suggests that the size of the task grows linearly with the time. In about 10 minutes the size is 5 times bigger. Then I tried the same code on under IRIX 6.5 with gpc-20010623. The output is crippled due to a bug but it shows the same symptom. It just keep on growing. The same code with the good-old gpc 2.0 runs for more than 20 hours without any problem. The memory management in the latest distribution must be fundamentally wrong. Have any of you experienced the same problem? Is there a compiler switch to force a more strict memory management mode? Help me please! miklos

Random function
by Charles Keeper 28 Sep '01

28 Sep '01

Hello, The following question concerns a friend of mine. As I am not at all familiar with GPC it might seem trivial to you. My friend tries to use the random function like this: " rand := random/exp(31*ln(2)); " When she compiles the program she gets the error " In function 'Rand' : undefined reference to 'Random' ". The question is: is the syntax correct or does GPC support random function? Her program runs correctly on UNIX, however UNIX is not always available, hence she needs to use Linux 7. Unfortunately I don't know what version of GPC is installed. Could you please help?
