grx again
by Toby Ewing 05 Jun '03

05 Jun '03

Hi, all I'm doing a new install of gpc with grx2.45 on a Win2000 machine. (1) The recent change in the compiler, from recognizing "integer(32)" to requiring "integer attribute (size=32)", means I needed to change line 59 of the grx.pas file accordingly. No biggie, just info. (2) My computer uses 1024 x 768 pixels in 16-bit color when running windoze programs, but the c-compiled modetest demo won't go higher than 1) 1024 x 768 x 1-bit, or 2) 640 x 400 x 8-bit. When I run the Pascal … [View More]

Overriding non-virtual methods by virtual ones
by Frank Heckenbach 05 Jun '03

05 Jun '03

I recently came about the issue of overriding non-virtual methods by virtual ones. GPC currently allows this, but it may be slightly confusing. BP allows it as well, so we shouldn't forbid it. But should we warn? (Always or unless `--borland-pascal' was given?) type a = object procedure p; end; b = object (a) procedure p; virtual; end; Frank -- Frank Heckenbach, frank(a)g-n-u.de, http://fjf.gnu.de/, 7977168E GPC To-Do list, latest features, fixed bugs: http://www.gnu-pascal.… [View More]

I am a delphi programmer. Nearly all Delphi code relies on the fields of an object being set to zero automatically. If gpc wishes to be compatible with Delphi it must have the option to do the same. In Delphi you cannot use an abject without calling its constructor so the initialisation of virtual methods is always done.

ArcSin, ArcCos
by Frank Heckenbach 02 Jun '03

02 Jun '03

For now I'm using the libm routines, since I'm not convinced that the alternatives are really better. For complex numbers, I'm adding the following, rather simple, routines. If Emil (or someone else) wants to provide more optimized/numerically stable versions, let me know. function Complex_ArcSin (z: Complex): Complex; var t: Complex; begin t := Ln (Cmplx (-Im (z), Re (z)) + SqRt (1 - Sqr (z))); Complex_ArcSin := Cmplx (Im (t), -Re (t)) end; function Complex_ArcCos (z: Complex): Complex; … [View More]

Problems with installing GPC under Red Hat 9
by Tomasz Kowaltowski 02 Jun '03

02 Jun '03

I installed gpc-2.1-with-gcc.i686-pc-linux-gnu.tar.gz under my previous Linux (Red Hat 8.) and it worked without any problems. I did the same under Red Hat 9. When I tried to compile a program 'gpc' complained: gpc: installation problem, cannot exec `gpcpp': No such file or directory I put then in /usr/local/bin a symbolic link: gpcpp ->/usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/gpcpp Now I got the message: gpc: installation problem, cannot exec `gpc1': No such file or … [View More]

Could anyone please tell me how GPC will align variables of most used types by default on Intel platform? (+)
by Ingvar Marny 29 May '03

29 May '03

Hi, dear All. I have made exhaustive (at least, hope so) search in the documentation and mail list archives but found only that "GPC will align variables according to maximum performance", but how exactly? On what boundary will be aligned Integer, Boolean, Longint, Word, etc. On what boundary will be aligned string, record, array, their elements and are there any differences between default alignment of variable without record and variable as record field? And, if possible, I need information … [View More]

Upper/lower case in identifiers
by Frank Heckenbach 22 May '03

22 May '03

As you probably know, GPC currently converts all identifiers to first letter upper-case/rest lower-case. Since this is often not nice, I plan to change this. This would affect at least the following things: - error messages - the file name chosen with `--transparent-file-names' (makes a difference only on case-sensitive file systems, i.e. not Dos/Windows); is this ok (to those who use this option)? - the file name prompt with external files without binding While I'm at it, it might be … [View More]
