[fpc-pascal] Compiling FPC for SPARC

[Mark Morgan Lloyd]

First, is this the best list to discuss this?

I've got rather agressive filtering in my mailing list gateway. If anybody tries
to send any attachments etc. to me please use markMLl.fpc2 .AT. telemetry .DOT.
co .DOT. uk.


I admit readily to being a beginner as far as FPC is concerned, and
inexperienced at Open Source development (SVN etc.) in general- SVN etc.

On an i386-linux system I've installed the FPC binaries in
/usr/local/fpc-2.0.2.i386 and the sources off ~/pascal/src (hence
~/pascal/src/fpc/compiler etc.) and can compile using "make cycle" to the point
where I can run the new fpc against hello.pp and get something that runs.
Questions at this stage:

*  Are there further validation tests available?
*  How can I build an installation bundle to move to a virgin machine?
*  What's the approved directory structure for an FPC binary+source tree
   for further work on e.g. Lazarus?

Moving to a SPARC (v8, 32-bit) system I installed the binaries in
/usr/local/fpc-2.0.0.sparc and the 2.0.2 sources similarly off ~/pascal/src.
Similarly running "make cycle" brought up a fairly obvious typo hence

Hope that's the appropriate kind of diff, sorry about any wrap.


Fixing the above and starting over, make runs up to

I propose to hold off any more tinkering for a few hours pending any light that
anybody can throw on this, or suggested ways forwards.

Is there an archive of the 2.0.0 sources somewhere that I can run the 2.0.0
SPARC compiler against as a check?
