Remove {$debug-statement}
by Frank Heckenbach 16 Apr '03

16 Apr '03

GPC has supported the compiler directive `{$debug-statement}', mostly as a way to ease "WriteLn debugging" in a time when debug info was mostly unusable (i.e., until a little more than a year ago ;-). Since debug info now works (perhaps with small bugs, but at least better than WriteLn debugging), I think we can drop `{$debug-statement}'. Or does anyone still need it for any purpose?

Bug: variable declared in a unit and masked in another
by Jean-Pierre Vial 13 Apr '03

13 Apr '03

One of my programs works fine with GPC2.1/gcc2.95.3 it does not compile with 2003/03/23 I could isolate the problem (out of a 5000 lines source) to two small units (see below) The original unit declaz contains global variables and procedure common to almost all the rest of the program. Ttwo of its (public) variables are masked in the implementation part of another unit by a variable with the same name (not a bug). There is a warning for this situation: fine, but not so fine, all the variables declared after the warning are ignored, and trigger errors when they appear later. To see it happen, copy the two sources below as gdeclaz.pas and gimpragr.pas, and try gpc --automake -c gimpragr.pas I get jp@brea:~/agreg/src/pascal> gpc --automake -c gimpragr.pas gimpragr.pas:21: redeclaration of `l132' gdeclaz.pas:6: previous declaration gimpragr.pas: In procedure `presidence': gimpragr.pas:23: undeclared identifier `president' (first use in this routine) gimpragr.pas:23: (Each undeclared identifier is reported only once gimpragr.pas:23: for each routine it appears in.) gimpragr.pas:23: undeclared identifier `presidente' (first use in this routine) ***************************************************************************** unit gdeclaz; interface var l132 : boolean; implementation END. ********************************************************************************* Unit gimpragr; Interface Procedure impression; Implementation Uses gdeclaz; Var l132, president,presidente,chrono: Boolean; Procedure presidence; Begin If Not (president Or presidente) Then Begin write('La prÃ©sidence est elle tenue par un homme ou une femme H/F ? '); End; End; { presidence } procedure impression; Begin writeln('impression'); end; END. ****************************************************************************************** -- Jean-Pierre Vial

Compiled gpc on cygwin but not sure what I have (where is gpc)
by Brian Keener 12 Apr '03

12 Apr '03

Hello all, As you can tell from the subject I am a real newbie to GNU-Pascal but I have an application I am trying to port to Cygwin and it has several pascal modules (originally from Borland Delphi) that I will need to compile so I am trying to get a working copy of gnu-pascal for my Cygwin install. I tried a binary install and it had a gpc.exe but the problem there was the binary was for cygwin and gcc 2.95.3 and cygwin has moved to gcc 3.2 and the binaries were compiled so they installed to cygnus/usr/bin instead of say usr/bin in cygwin so I couldn't really use the binary as it could not find all the 2.95.3 libraries for gcc it needed. I was going to try the install-gpc-binary script but was unsure if it would shorten the path so it would work if I copied to usr/bin as opposed to lengthening as if I had installed to /usr/local/cygnus.... So instead I decided to try to compile my own and attempted to follow the compiling instructions from the Website for gnu-pascal. I used cvs from the cygwin site to get the gcc sources for Cygwin for the 3.2.1 release and then I downloaded the gpc sources from website for gpc-20021128 which is supposed to work with gcc-3.2.1. I then created the symlink for p as described in the instructions and then I created a build directory and from there I ran the configure line and the make line as documented. I think I have done everything correctly but after compilation I am still not sure I have all I need. If in my build directory I do a find for gpc - I have the following: /usr/develop/obj $ find ./ -name "gpc*" -depth -print /gcc/gcc/p/gpc.o /gcc/gcc/p/gpc-common.o /gcc/gcc/p/gpc-decl.o /gcc/gcc/p/gpc-lex.o /gcc/gcc/p/gpc-typeck.o /gcc/gcc/p/gpcpp.o /gcc/gcc/p/rts/gpc.gpm /gcc/gcc/p/rts/gpc.gpi /gcc/gcc/p/rts/gpc_sp.gpi /gcc/gcc/p/rts/gpc_ep.gpi /gcc/gcc/p/rts/gpc_bp.gpi /gcc/gcc/p/rts/gpc_delphi.gpi /gcc/gcc/p/rts/gpc.o /gcc/gcc/gpc1.exe /gcc/gcc/gpcpp.exe /gcc/gcc/gpc-run This appears to be correct except that I don't see a gpc.exe like what existed in the binary install I did. I am really unfamiliar with pascal (I have often thought I would like to learn but...) but as I said I have an application I am trying to port to Cygwin and it has several pascal modules (originally from Borland Delphi) that I will need to compile. I see some warning but doesn't really seem to be any show stopper errors. Is anyone familiar with Cygwin enough to offer some pointers on compiling. Brian Keener bkeener(a)thesoftwaresource.com

ld.exe error...
by Dominique Louis 10 Apr '03

10 Apr '03

Hi all, During the compilation of a project using the DevPascal IDE and the latest release, I get the following error... C:/Progra~1/Borland/gpc/bin/ld.exe: cannot find -lsdl I gather that "sdl" is the DLL that ld.exe is looking for, but where should it be placed so that it can find it. The SDL exists in the System32 directory as well as int he same directory as the project and it still does not find it. I have not had a response to my previous emails, so am starting to wonder if I have broken some kind of protocol before posting here? Any clarifications welcome. Sincerely Dominique http://www.DelphiGamer.com := go on, write a game instead;

SizeOf sets (was: packed enumerated types?)
by Adriaan van Os 08 Apr '03

08 Apr '03

In the testprogram below, SizeOf( enum33) returns 4, which seems to me to be a bug. Regards, Adriaan van Os ---------- program test; type enum08 = ( a01, a02, a03, a04, a05, a06, a07, a08); enum16 = ( b01, b02, b03, b04, b05, b06, b07, b08, b09, b10, b11, b12, b13, b14, b15, b16); enum17 = ( c01, c02, c03, c04, c05, c06, c07, c08, c09, c10, c11, c12, c13, c14, c15, c16, c17); enum32 = ( d01, d02, d03, d04, d05, d06, d07, d08, d09, d10, d11, d12, d13, d14, d15, d16, d17, d18, d19, d20, d21, d22, d23, d24, d25, d26, d27, d28, d29, d30, d31, d32); enum33 = ( e01, e02, e03, e04, e05, e06, e07, e08, e09, e10, e11, e12, e13, e14, e15, e16, e17, e18, e19, e20, e21, e22, e23, e24, e25, e26, e27, e28, e29, e30, e31, e32, e33); set08 = set of enum08; set16 = set of enum16; set17 = set of enum17; set32 = set of enum32; set33 = set of enum33; begin writeln( 'SizeOf( enum08) = ', SizeOf( enum08)); writeln( 'SizeOf( enum16) = ', SizeOf( enum16)); writeln( 'SizeOf( enum17) = ', SizeOf( enum17)); writeln( 'SizeOf( enum32) = ', SizeOf( enum32)); writeln( 'SizeOf( enum33) = ', SizeOf( enum33)); end.

grx and gpc problems
by Toby Ewing 06 Apr '03

06 Apr '03

Hi, all Trying to compile a program, I suddenly see: > Internal GPC problem: internal option '--amtmpfile' not given I had compiled the program successfully a few minutes earlier. I get this problem with every program that USES GRX that I attempt to compile. But When I attempt to compile a program that doesn't USE GRX, I see > cannot file -lgcc Any guesses? GPC was working fine for me a few weeks ago. I'm using 2.1 (20020510) based upon 2.95.3 (20010315), under win2000, installed only a few months ago. thanks, Toby

Time functions in gpc.pas
by Markus Gerwinski 05 Apr '03

05 Apr '03

Hi folks, does somebody know a way to get the TimeZone from the system? In gpc.pas, the procedure UnitTimeToTime wants it as a parameter, so I want to fill in a reasonable value. Besides, the function expects parameters named DST, TZName1, and TZName2. Can somebody tell me what they mean and how to find reasonable values for them? Thanks, Markus
