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.

Re: Char type...

According to Orlando Llanes: > Is there a Char type that is guaranteed to be 16-bits from now until > infinity? > Is there a Char type that is guaranteed to be 8-bits from now until > infinity? > Does GPC/DJGPP support the Unicode character type? No(t yet). You can work around this by using 8-bit and 16-bit integers: Type Char8bit = Cardinal ( 8 ); Char16bit = Cardinal ( 16 ); These are guaranteed to be 8/16-bit from now until "infinity" - whenever that will be. ;-) Some "wide char" (Unicode) fragments already exist in GPC. If somebody wants to take part in implementing such things (and others), be welcome.

There is no overhead in functions declared with any of these directives. However there *is* overhead in the compiler who has to deal with all those different directives - and in the programmer who has to remember them. ;-) Peter -- Peter Gerwinski, Essen, Germany, free physicist and programmer Maintainer GNU Pascal - http://home.pages.de/~GNU-Pascal/ - 1 Oct 1997 PGP key fingerprint: AC 6C 94 45 BE 28 A4 96 0E CC E9 12 47 25 82 75 Fight the SPAM! - http://maps.vix.com/

ASMName...
by Orlando Llanes 26 Jan '98

26 Jan '98

I was wondering if there was any overhead in calling a function declared in the GPC with the ASMName. In other words, if I had the following code... ---------- DJGPP: ---------- void cfunc() { // Do something } ---------- GPC: ---------- PROCEDURE CFunc; ASMName 'cfunc'; PROCEDURE PFunc; BEGIN { Do something } END; ...and invoked them as follows... BEGIN CFunc; PFunc; END; Would PFunc run faster than CFunc? The reason I ask is because I remember Peter saying a long time ago that the C; keyword added overhead to a function and I wonder if the same is true for the ASMNames keyword. Thanks in advance!

Char type...
by Orlando Llanes 26 Jan '98

26 Jan '98

I have a couple of Char type questions: Is there a Char type that is guaranteed to be 16-bits from now until infinity? Is there a Char type that is guaranteed to be 8-bits from now until infinity? Does GPC/DJGPP support the Unicode character type? Thanks in advance! See ya!

Re: coff file structure

Hi, Omar! Hi, all! According to Omar Abu Al-Haija: > Another question could you please tell me where I can get more > information about coff files , I would like to know more about the > structure of these files and i would like to look on the differance > between coff and MS obj files. Section 17.5 of the DJGPP FAQ list has some pointers that might help you. In particular, they mention a conversion tool: `OBJ2COFF' is available from the Oulu repository, e.g. ftp://x2ftp.oulu.fi/pub/msdos/programming/convert/o2cv10.arj and from DJ Delorie's ftp server, e.g. ftp://ftp.delorie.com/pub/djgpp/contrib/o2cv06.arj. If that tools comes with source (I don't know), you can probably extract anything about COFF from it. > Ps. this time I put subject , hope that could make beter gnu pascal :-) Thanks! :-) Yours, Peter -- Peter Gerwinski, Essen, Germany, free physicist and programmer Maintainer GNU Pascal - http://home.pages.de/~GNU-Pascal/ - 1 Oct 1997 PGP key fingerprint: AC 6C 94 45 BE 28 A4 96 0E CC E9 12 47 25 82 75 Fight the SPAM! - http://maps.vix.com/

[Fwd: Re: GPC 971001 problems on redhat linux 4.2] (fwd)
by Tom Dye 22 Jan '98

22 Jan '98

Hello all, Ken is kind to describe my efforts as successful. Initially, I set out to test the idea that an old libc was to blame, but I soon realized that tinkering with gcc is not trivial and that it was very easy to break things. With regards to the bug mentioned, this is fixed by a patch that Peter posted to the list in November. In my experience, however, the patch exposed other apparent bugs having to do with parameter passing that I was not able to investigate fully. Like Ken, I've had other things come up and haven't been able to get back to 971001. My advice, which is influenced very heavily by the small amount of time I can spend writing Pascal programs and might not be useful for someone with more time and an inclination to get deeply involved with gpc, is to resist the urge to tinker with the alpha releases and wait for a beta release. On the other hand, it would be interesting to know why 971001 gave so many of us problems. Tom Thomas S. Dye, Ph.D. Home: 813 16th Avenue, Honolulu, Hawaii 96816. Voice (808) 734-2087.

Ken, if you are reading this, did it? > Hi All, Well, I was able to make it work once, quite a while ago (November I think) by recompiling. Having an older libc was not the direct problem. Since then, as life insists, priorities change. I have not been able to do much with the newer releases due to time constraints. HOWEVER, Tom Dye was much more successful than I with the more recent ones. If you are there Tom, have you had success compiling the more recent GPCs and using them?
