Incompatible graphmath.ppu unit

[Chris Hall]

The solution is to remove the graphmath unit ppu file in the .lazarus user directory and then have lazarus recompile or use the unit in the usr/lib directory. I've only tested with the default lazarus empty form program, but this problem shows up immediately.

I'm not sure how useful this info is, but I just compiled Form1 on Debian (bookworm) and I don't see any issues.

@ginggs, Ubuntu applied one patch, do you think that may be related?

I had the problem when trying to compile form1 on ubuntu 22.04 (jammy)
that had been upgraded from 21.10 (impish). The upgrade removed lazarus
and fpc from my machine and I had to re-install lazarus. Whatever the
package install process does, it puts an incompatible graphmath.ppu in
your .lazarus directory structure. Removing that ppu solves the problem
as then lazarus seems to use the unit in the usr/lib directory
structure. This bug occurred on 2 separate machines.

The upgrade process *should not* remove lazarus and fpc, that's a bug. Do you happen to have the logs of when this happened such that we can figure out why there were removed?

However, the install process doesn't put anything in .lazarus. If anything, that's left over from the previous version (as stuff in the home folder is not to be touched during removal). Apparently lazarus doesn't handle old local files in the home folder gracefully.

I don't know where a log would be. But the upgrade did remove bothe
Lazarus and fpc on both machines.
