FreeBSD gpc status?
by Frank Jahnke 09 Mar '04

09 Mar '04

I am writing you all to inquire about the status of the GNU Pascal compiler on FreeBSD. It is mentioned quite prominently on the gpc homepage as a supported platform, yet it is not in the FreeBSD ports collection. Browsing the archives on gnu-pascal.de shows some intermittent interest, but no real success stories, at least for recent OS versions. I have quite some old pascal code that I would like to use with the rest of the GNU compiler family. gpc would seem to be the way to go, if that would be possible. Could anyone share with me what the status of gpc is on FreeBSD? For what it's worth, I'm running FreeBSD 5.2.1 with gcc 3.3.3. Frank Jahnke

bug (?) in Time Format
by Toby Ewing 07 Mar '04

07 Mar '04

Hi, all There have been some recent improvements to the Mersenne Twister (the random number generator that is used in the GPC unit), and I've been translating them into Pascal for eventual submission to the programming team. As part of this, I wanted to check the execution time, so I wrote a timer (I thought!) into a test program: program testMT; uses GPC, MTrand; {MTrand is the name of the unit I'm working on} const big = 10000000; TimeFormat = ' %Q'; var t1, t2, i, j : medCard; CurrentTime : TimeStamp; begin SeedRand(1234567890); GetTimeStamp (CurrentTime); WriteStr(FormatTime(CurrentTime, TimeFormat), t1); { line 17 } for i := 1 to big do j := randInt; GetTimeStamp (CurrentTime); WriteStr(FormatTime(CurrentTime, TimeFormat), t2); Writeln('Elapsed time: ', (t2 - t1):1); end. The compiler hangs with the following error: testmt.pas(17): Error: reference expected, value given testmt.pas(17): Error: reference expected, value given testmt.pas(17): Error: tree check: expected class 't', have 'x' (error_mark) in require_complete_type, at p/typecheck.c:63 Please submit a full bug report I'm guessing that it's not about my unit, but rather what I'm trying to do with capturing a string into an int... anyway, here is a bug report.

About GPC's support of func/proc overloading
by Neil Santos 07 Mar '04

07 Mar '04

How does GPC support function/procedure overloading when it allows the declaration of parameters to be skipped when it comes to the implementation of a function/procedure? I read somewhere that a function/procedure declaration in an interface need not be duplicated for the implementation. UIM, the text referred to Extended Pascal. Say function foo is declared like this in the interface section of a module: function foo(bar : integer) : some_return_type; In the implementation, one could just do: function foo; begin {do interesting stuff here} end; Is it possible to overload foo (i.e., to accept a baz parameter, aside from bar) without resorting to having two code blocks with slightly different parameter declarations? And on a slightly related question: Does GPC support, as an extension to Pascal, optional paramaters the way Ada supposedly does? If so, could someone please point me towards the direction I should go in order to find out how? If not, does anyone else think that this would be a useful extension?

Problem with 20030830 alpha install
by Armsdon, Phil 06 Mar '04

06 Mar '04

Hi all, I have GPC 2.1 20020510 installed from source on a Sun solaris 2.8 machine with all the associated pre-requisites with gcc 2.95.3 I am now trying to install the alpha version of GPC 2.1 20030830 on the same machine. I am using all the same pre-requisites and the same copy of gcc 2.95.3 I am getting a problem with this compilation at teh configure stage. When I run configure --prefix=/opt/ACMLgpc --enable-languages=pascal with the alpha version, I get an error message just after I confirm the action to patch the source: *** *** Detected GCC version 2.95.3. *** GPC 2.1 requires a patch to GCC to build with version 2.95.3. *** This patch will now be applied. *** Press ENTER to continue, Ctrl-C to abort. *** *** Creating dummy ./p/Makefile.in ./configure: syntax error at line 8403: `fi' unexpected Configure in /opt/ACMLgpc/src/gcc-2.95.3/gcc failed, exiting. Has anyone seen this error message? Any idea how to fix it?

Dereferencing variables of type Pointer
by Neil Santos 06 Mar '04

06 Mar '04

Isn't there any (presumably non-standard) way of dereferencing Pointer variables? The reason I ask is because I need information on the type of variable whose address a Pointer variable contains. Said type will vary, and cannot be known until runtime. If that can't be done, then could somebody please give me tips on writing generalized subroutines for reading and writing typed files? Or should I just skip both of these and just write an interface object, and implement read/write mechanisms for each structure I intend on keeping in a stream? I'd rather avoid this (for it beats the whole point of OO, IMO), but I'd do it if it can't be avoided. TIA. [Hrm... Or maybe I'll do it in Ada, with generics. But, aside from knowing Pascal which is from the same family, I know nothing of Ada.] -- - Neil Santos Freelance Programmer & Web Designer - - http://nsantos.f2o.org/ Free Software advocate - -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GAT d+@ s+:+ a?

How to start ?
by Prof. Harley Flanders 04 Mar '04

04 Mar '04

Hello O/S: Windows XP I would like to get started with GNU PAscal. What must I download to have a Pascal compiler, and possibly an IDE? The download instruction on the GNU site are not too clear. Must I download the source code for the Pascal complier, and then download a C (or other compiler) to compile the Pascal compiler? Or can I (hopefully) get the latest Pascal compiler ready to run? Thanks, HF =========================================== Prof. Harley Flanders 3533 Windemere Court Ann Arbor, MI 48105-2867 Home: 734 668 1546 harley(a)umich.edu Visiting Professor University of Michigan Dept. of Mathematics, East Hall Ann Arbor, MI 48109 734 764 6451 Secretary: 734 764 6485 FAX: 734 763 0937 ===========================================

GPC, Mingw and gcc-3.3.3
by Prof A Olowofoyeku (The African Chief) 02 Mar '04

02 Mar '04

Hiya I built gpc-20030830 on gcc-3.3.3 under Mingw. It built okay, but there are problems with (inter alia) "FExpand". For example, this program: PROGRAM bug1; USES gpc; BEGIN Writeln (FExpand ('.')); Writeln ('Ok'); END. produces this result (gdb output): "Starting program: D:\gpc\test/bug1.exe Program received signal SIGSEGV, Segmentation fault. $0041f369 in Internalrealpath ()" Everything works fine when gpc is built on gcc-3.2.3. Anything later than that, and you get problems in Internalrealpath() as above. I am not sure why ... Best regards, The Chief -------- Prof. Abimbola A.
