Hi!

I first download GPC from mirror sites:
ftp://ftp.funet.fi/pub/mirrors/simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/gpc20bb.zip


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?

From Dos command line Gpc compiler:
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!

Veli Suorsa
