Hi,

For a while now I've been getting the following error when building from svn (2.3.1 from 20 mins ago).
The last known good build I have is from 3rd. Jan but I think it was ok in Feb also. I build about once a month but don't always do an install.
I've looked at the change history for all the files which seem to be involved but I can't see which change caused the problem.

Any ideas?

You could try this:

Being back from the US now, I hope to be able to have a look at it in foreseeable future.

Yes thanks, I have been doing just that.

I started by checking out a new tree of fpc, not fpcbuild which I have been using until now, with the last revision which worked, r9623.

These are the results using a 2.2 snapshot from 3-11-07: r9623 good
r9800 fail, exeinfo problems
r9803 good
r10000 fail, unknown directory imlib
r10100 fail, missing endif in packages/makefile
r10103 fail, unknown directory test
...
r10888 to 10994:

-------------------------------------------------------------------------- Revision 10888 is:
Modified Mon May 5 18:46:55 2008 UTC (12 days, 16 hours ago) by micha
* regenerate Makefiles to get armeb-linux support globally (also arm-darwin, so it seems)

The 'unknown directory test' appears to be still left over from the restructuring at the beginning of this year.

It should be noted that although the build process did not complete, the compiler itself appears to have built ok.

The second thing to notice is that the fpcbuild tree fails with a different error, '_excptregptr defined twice'.

The results are the same in both cases when I use my 2.3.1 compiler from 3rd. Jan.

HTH,
Dave

The problem seems to be that _excptregptr is defined in system.pas and prt0.as but it was only recently exposed by the makefile regeneration.
I've changed it here as follows:-

Index: system.pas
=================================================================== --- system.pas (revision 11013)
+++ system.pas (working copy)
@@ -484,7 +484,7 @@

 var
-  ExcptReg: PExceptionRegistrationRecord; public name '_excptregptr';
+  ExcptReg: PExceptionRegistrationRecord; external name '_excptregptr';
 {$ifdef SYSTEMEXCEPTIONDEBUG}
 var
===================================================================

However, now I have another problem:-
make[4]: Leaving directory `F:/fpc/fpcbuild/fpcsrc/packages/tcl' make[3]: *** No rule to make target `opengl_all', needed by `gtk1_all'. Stop. make[3]: Leaving directory `F:/fpc/fpcbuild/fpcsrc/packages' make[2]: *** [packages_all] Error 2

make[1]: Leaving directory `F:/fpc/fpcbuild/fpcsrc' make: *** [fpcsrc/build-stamp.i386-os2] Error 2

I don't know whether you read my earlier reply concerning the crash in the 'fpc' checkout, but it is still there. I can not find any differences apart from the slightly different directory structure, but it is still there and consistent irrespective of which compiler, make or whatever I use.

Cheers,
Dave

Speaking of OS/2, can sb quick-look at the FAQ page ( http://www.hu.freepascal.org/faq.var ) to see if the 1.0.6 stuff can be moved to the wiki ?

Not sure if I understand the question properly, but if you want to cleanup current FAQ by moving references to problems only relevant for very old version to some other place, the OS/2 related one doesn't need any special exception as long as you keep the current version there - "1.0.6 and higher" is still applicable for the latest versions, because the requirement for TZ environment variable comes from unzip.dll which is still used.

Yeah, I noticed meanwhile. We could remove the double heading though.
