Can someone please clarify the "parentage" of the Pascals (plural) available under Linux.
There seem to be two distinct ones. There is gpc, the subject of this list, and a seemingly distinct route via p2c and the gcc "C" compiler.
Am I confused ? Are they really separate, and why (if true) are there two rival Pascals. How do they differ ? Are they both Gnu ?
I would imagine that the adherents of this list prefer gpc :)
Which of them is the easiest to provide with a TP7.0 style Graph Unit ?
TIA Best regards.

- p2c is just a kind of filter. You process your pascal sources through p2c and get some C files which you can process with gcc. - gpc is a Pascal compiler. It is based on the top of gcc, a C compiler, but you do not see anything of C.

GPC is the GnuPascalCompiler. If you want to use Pascal just use this one :-)
Try this out:
test.pas: ------------------- program hello; begin writeln('hello geoff bagley') end. -------------------
process this source with gpc test.pas -o myprog and run myprog afterwards.

There are even more than these. There is also
FPK: http://www.freepascal.org/ which is written in itself
and
Kylix: http://www.borland.com/kylix/
which is Delphi for (Intel-)-Linux

This one also has a Graph. (based on svgalib, seems to work on FreeBSD too)
and

Besides this, also Virtual Pascal has some way to generate Linux binaries IIRC, but that is more a hack. (www.vpascal.com lists it as experimental)

I don't know about p2c.
But there's is a third, completely separate one: FPC http://www.freepascal.org
In general FPC has better compatibility with Turbo Pascal. I know FPC has a good graph implementation.
In general FPC is more stable (if you use version 1.04/1.05) than gpc, and development on it is very heavy.
FPC is also a lot faster, but not available on all unix systems, as gpc is. But FPC has almost all features of Delphi, there's even a project called Lazarus developing a VCL like library and IDE.

faster for what ? For compilation time I agree, for execution time it is typically 30 to 80 % slower (for djgpp and mingw32 implementations I am able to check). And of course these difference are not unrelated.

I'm very concerned about this topic. Whenever I ask anything to the list, someone from fpc sends me private emails about things not really related to my question but with a hint to fpc.
*** I'm not interested in fpc! ***
And I don't want to read anything about a comparison between GPC and fpc. Furthermore I don't want to join the fpc team and I don't want to read any advertisings about this so called compiler.
'nuff said!
