I recently encountered a problem with clashing .ppu files - see the
thread in the lazarus mailing list "Strange problem compiling IDE". I
found it difficult to track down, and it would have been much easier if
the full pathname had been given. Looking at the compiler source this
looks like a trivial change - see attached patch. The error message then
changes from
Warning: Recompiling Expr, checksum changed for spe.ppu {impl}
to:
Warning: Recompiling Expr, checksum changed for
/home/me/fpc/lazarus.w/components/tachart/lib/i386-linux/gtk2/spe.ppu {impl}
The former took me a long time to fix, whereas the latter points
immediately to the problem (a local copy of something in the fpc numlib
package).
Is this a sensible change?
