I am having a strange problem when compiling the IDE (current svn for

Warning: Recompiling Expr, checksum changed for spe {impl}
"changed for spe"
either spe got recompiled, or you have 2 different spe.ppu
This happens for example when you
- have 2 spe.pas
- when you have search path for units that overlap (one spe.pas, but
visible in the search path of 2 packages)
Expr.pas(78,12) Fatal: Can't find unit Expr used by FormGrid
It turns out the problem was indeed a duplicate spe.pas; the culprit was
components/tachart/numlib_fix/spe.pas
simply deleting this file allows the IDE to compile. (I don't use the
tachart package). This is very difficult to figure out looking at the
error messages as described in my earlier message; looking back very
carefully on the -vt output I can see that there is a ppu loading
message on the tachart unit, but then the compiler keeps on looking
for spe.pas, with no indication at that point that the .ppu has been
rejected. The volume of output doesn't help.
I do a lot of recompilations of the IDE, I am a heavy user of TAChart,
and I also have programs in which spe is used: I have never seen this
issue. I can't remember why Alexander had to add this local copy of the
numlib file, it certainly was a workaround for some issue. If I compare
the spe of fpc3.02 with that local copy I don't see any essential
differences. Therefore, I removed spe from the numlib_fixes folder of
TAChart today.
But: in numlib_fixes there are other local copies of numlib files. They
contain workaround fixes of issues with the original files. The fixes
were made by Alexander, and I don't know which issues they address. At
the moment I am working with numlib and have some patches in the bug
tracker, but progress is slow since I don't which write permission
there. But I can promise to try to remove the duplicated numlib files
from TAChart in the long run.
But nevertheless, as mentioned in the beginning, I don't think that
these files are the reason of the compilation issues that you mention.
If that were true then anybody would have them - at least I don't.
