gpc return value
by Oldham, Adam 21 Mar '01

21 Mar '01

It doesn't appear that gpc has a return value. I've seen compilers that will return non-0 for a file that failed to compile and a 0 for success. Is there a flag to enable this in GPC?

I first download GPC from mirror sites: ftp://ftp.funet.fi/pub/mirrors/simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/gpc… It does not work with latest Rhide and Dos/ Djgpp. I tried (with Big African Chief help) sites: ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/djgpp/gpc20ab.zip It does not work with Rhide, neither. And I got a new download- siteaddress from CloseBSD, which works: ftp://agnes.dida.physik.uni-essen.de/home/maurice/gpc2952b.zip >What exactly does not work and what are error messages ? I saw from Rhide screen command: gpc -o pay3_4.exe --automake="-g" -g pay3_4.pas -lgpc -lm before editing djgpp.env file. and error message was like: ... undefined reference to '-p-inoutres' ... collect2: ld returned 1 exit status Adviced GPC version works with Rhide Menu in two parts: -compiler and -make, not yet -Build all. Can you tell me why -Build all does not works? gpc -g -c pay3_4.p -o pay3_4.o works, ... and make: gcc -o pay3_4.exe pay3_4.o -lgpc -lm works, too. I had to do some adds/ changes to djgpp.env file like: [gpc] COMPILER_PATH=%/>;COMPILER_PATH%%DJDIR%/bin [rhide] RHIDE_TYPED_LIBS_DJGPP.p=gpc m RHIDE_TYPED_LIBS_DJGPP.pas=gpc m PASCAL_TYPE=GPC RHIDE_LD_PASCAL=gcc RHIDE_COMPILE_GPC=$(RHIDE_GPC) $(RHIDE_GPC_FLAGS) $(LOCAL_OPT) -c $(SOURCE_NAME) -o $(OUTFILE) RHIDE_COMPILE_LINK_GPC=$(RHIDE_LD_PASCAL) $(RHIDE_LIBDIRS) $(C_EXTRA_FLAGS) -o $(OUTFILE) $(OBJFILES) $(LIBRARIES) $(RHIDE_LDFLAGS) $(LDFLAGS) $(RHIDE_LIBS) RHIDE_COMPILE_LINK_PASCAL_AUTOMAKE=$(RHIDE_COMPILE_LINK_$(PASCAL_TYPE)) And so on... You can see all these Rhide variables from saved *.mak file. I really hope that someone do a good installation program (and instructions, too) for these variables. My test program (pay3_4.p, that you have seen before) size of .exe file (436 kb) is 3 times larger than Fortran (150 kb). Strip helps to 300 kb, but is there anywhere a better optimizer? I really think that someone can do it with assembler within 1 KB. Thank you very much and see you soon!

GPC could do the same. ??? How should the compiler know? I mean, the object type of a pointer at runtime is a matter of runtime. Yours Markus

this is probably a really bad question
by Oldham, Adam 20 Mar '01

20 Mar '01

But, I didn't see it in the documentation. When creating a new variable in a function or main part of a program: temp : String[30]; Does the compiled code when run, automatically zero out the new variable temp? It either appears that is does, or the memory used in my apps was already zeroed to begin with. Thanks again, Adam Oldham ----------------------------------------------------------------------- C.

set constructor elements must be of ordinal type
by Oldham, Adam 20 Mar '01

20 Mar '01

If I have: DownChrSet : SET OF CHAR; LowerT = '\C2'; DownChrSet := [LowerT]; I get the above error. Isn't Char an ordinal type though? And \C2, being a hex, fits into one char, so shouldn't this be ok? Adam ----------------------------------------------------------------------- C. Adam Oldham Marconi Commerce Systems Inc.

Suggestion: contributed units
by Eike Lange 20 Mar '01

20 Mar '01

Hi! There are a lot of units, someone has contributed. E.g. there is your email-unit, Nicolas svga-unit, my *sql unit and a lot more, which aren't in the GPC distribution. I'd like to suggest a _short_ description for each of these whithin our documentation. A possible good place could be Using GNU Pascal -> External Resources What d you think? Eike

Need GPC installation
by Mr. Veli Suorsa 19 Mar '01

19 Mar '01

Hi! I use latest Rhide and it works fine with Gnu C/ C++ and Fortran compiler. Some new features are still hoped ;-). I have tried to install GPC to Dos / Djgpp (from download sites a zip-file, >gpc20bb.zip). Can You help me, because I need pascal to my test and Gpc compiler don't works? Or can you tell me who can solve this problem! I have read your instructions and done all right, but they are not good enough to succeed installation in Dos / Djgpp. What should I do? With Best Regards and Thanks in advance! Veli Suorsa --- "People must believe to the future to be able to live!" ---------------------------------- J.V.Snellman, 1890.

Qualified Idents, possible work around...
by Orlando Llanes 19 Mar '01

19 Mar '01

I just thought of something, there could be one of two ways to call a "duplicate" function. The first way is using asmname, would that work with GPC compiled programs? The second way is to call the function by inserting Assembly Language. As for variables, would the above two methods work for them as well? See ya! Orlando
