Re: Need GPC installation

Thanks for your reply! >> ftp://agnes.dida.physik.uni-essen.de/home/maurice/gpc2952b.zip >OK. I try to always give under this same link the lastest gpc snapshot I have compiled, and which give zero error when >running the whole test suite. I just updated gcc-2.95.3 version of Djgpp. Every other compiler seems to work well (Thanks to Andris). Can You update this Pascal compiler (gpc2953b.zip) and documentation and inform me (download site), too? >To force a build in pascal you need to replace --automake by --autobuild as compilation option. >But this is nowhere provided for in rhide (and in particular is not done when you hit compile/build) because of the >different logics: looking into the makefiles generated by rhide you have provision for RHIDE_COMPILE_LINK_AUTOMAKE but >not for RHIDE_COMPILE_LINK_AUTOBUILD I hope they add this --autobuild as a compilation option to next version. >You have probably an older version of rhide.

bug for external if var is a text...
by Fabio Casamatta 29 Mar '01

29 Mar '01

Dear GPC, I need to do the following thing: in a main program I write on a file but the "text" variable is declared in another unit. The program is the following: program demofile; var test_external_value: integer; external; asmname 'external_value'; var f: text; external; asmname 'f_test_external'; begin writeln('value of test_external_value=', test_external_value); writeln('Create the file FILEDEMO'); {$I-} Assign(f, 'FILEDEMO'); ReWrite(f); {$I+} writeln(f, 'file written by program demofile'); close(f); end. The unit is the following: unit demofileunit; interface implementation var test_value: integer = 7; asmname 'external_value'; var f_test: text; asmname 'f_test_external'; end. Then I compile: gpc -c demofileunit.pas gpc -o demofile demofile.pas demofileunit.o running demofile: value of test_external_value=7 Create the file FILEDEMO demofile: `Unbind' applied to non-bindable TFDD file `(null)' (error #404 at 8049938) this is the errore received and FILEDEMO is not created. If I replace in demofile.pas the line: var f: text; external; asmname 'f_test_external'; in the line var f: text; so that f is not external, compiling and running again demofile: value of test_external_value=7 Create the file FILEDEMO and the content of FILEDEMO is: file written by program demofile Then, all is ok. I installed GPC 2.95.2 with Linux RedHat 7.0 (then gcc is 2.96, but I don't think it is important...) It seems that it is not possible to link "text" variable externally as I do with other types...Is it a bug? Thanks Fabio Casamatta

"mallinfo" in GPC?
by Tomasz Kowaltowski 27 Mar '01

27 Mar '01

In gcc one can use the function "mallinfo()" in order to know, among other things, the amount of dynamic storage currently allocated by the program through "malloc()". I use it to check for program memory leaks. I would like to know whether there is anything similar for gpc? -- Tomasz Kowaltowski

glibc et. al.
by Prof. A Olowofoyeku (The African Chief) 26 Mar '01

26 Mar '01

Hi all Pardon this ignorant question - what gives with glibc and how (if at all) does it affect GCC and GPC on any platform? I keep coming across various things about glibc, and AFAIK it has no relevance to GPC at all (it seems to be only for GCC people - and then, only for some platforms). Am I missing something?

Bug report: Object interface/implementation conflict
by Markus Gerwinski 25 Mar '01

25 Mar '01

Hello Folks! Got the following bug today: type ... tPruzzel = object Procedure amazooka ( proe: pProe ); end (* tPruzzel *); ... tPruzzel.amazooka ( p: pProe ); begin (* tPruzzel.amazooka *) --> if p = nil then ... end (* tPruzzel.amazooka *); The "-->" marked line yields a compiler error: "undefined identifier 'p'". To avoid it, the variable _identifier_ in interface and implementation must be the same. I don't know, if this case intentionally yields an error; anyway, I think it should be a "header does not match", not an "undefined identifier". The latter one's confusing. Yours Markus

[BUG REPORT] Set in procedure

25 Mar '01

Hello, Here is a surprising bug I discovered. It's about variables of the set type in procedures. ---------------------------------------------------------------------------- -- Program SetBug2; Procedure Try; Var X : Integer = 1; OneSet : Set Of Integer = [1]; Begin If X In OneSet Then Writeln('OK') End; Begin Try End. ---------------------------------------------------------------------------- -- If I define 'OneSet' like this : Const OneSet = [1]; the problem disappears... And if the main program is : Var X : Integer = 1; OneSet : Set Of Integer = [1]; Begin If X In OneSet Then Writeln('OK') End. there is no problem.
