[SOLVED ]incompatible ppu=....timepopup.ppu
lazarus / 31-LCL

When I tried to recompile one of my projects - XMLTreeEditor, last
compiled about a year ago, September 2015 I guess, I suddenly got the
error:
editbtn.pas(35,65) Fatal: Cannot find TimePopup used by EditBtn,
incompatible ppu=C:\lazarus\lcl\units\x86_64-win64\timepopup.ppu,
package LCLBase

The ppu does exist in the location, and I am a bit of a loss why it
became incompatible. The Lazarus is stable release:
Lazarus 1.6 r51630 FPC 3.0.0 x86_64-win64-win32/win64

The same message appears when I compile this project on Linux Mint,
with apparently different path, but again the ppu is found where
indicated (same version of Lazarus for Linux/GTK2).

I tried to re-build Lazarus, but this did not help.

I have no issues with other projects, although this one maybe the only
project where TEditBtn component is used.

Any idea, how this issue can be fixed?

Thank you!

[SOLVED] at least partially by re-installing of Lazarus and removing
TEditBtn from the project.

Check that the same ppu-file doesn't exist in any another place.

timepopup.ppu sits in
C:\lazarus\lcl\units\x86_64-win64
 (on Windows machine) along with timepopup.lfm and timepop.o.

timepopup.pas is in
C:\lazarus\lcl\forms
along with another identical copy of timepopup.lfm

No other copies found anywhere inside C:\Lazarus folder.

Maybe the culprit is another third-party package using TEditBtn? Which
packages does your project require?

I avoid using any third-party stuff unless there no other way.

My suspicion is that source code for TEditBtn does not match pre-
compiled ppu which comes with the Lazarus installation. Something in
my play with the project triggered LCLBase re-compilation; Lazarus
stuck with wrong timepopup.ppu and not found ShowTimePopup and stopped
working at all (stopped compiling anything, I mean).

I have re-installed it over the existing installation and now it
works. But if I open EditBtn.pas or it opens itself as the result of
previous unsuccessful compilation, Lazarus fails with the same error.

I am going to replace the EditButton with EditBox+SpeedButton pair and
mark this topic as solved (by mean of Lazarus re-installation).

Thank you everybody for your help.

Does it also say something like 'checksum changed for unit xxx' before
the error message?
In this case it would be package dependency/search path problem.
Also try Clean up and Build.

@tk, Yes, it did; there were also messages about duplicate paths. But
I could not figure out what I should remove from or add to project
paths. Eventually Lazarus started complaining about that unit
regardless of what project was loaded. I removed everything from
project paths: Other unit files (-Fu) and Libraries (-Fl) sections and
reinstalled Lazarus. After this I can compile the project, but still
get lots of "duplicate" messages, like:
Note: Duplicate unit "interfaces" in "XMLTreeEdit", orphaned ppu
"C:\Projects\lazarus\XMLEditor\xmltreeedit-
code\lib\x86_64-win64\interfaces.ppu"
Note: Duplicate unit "interfaces" in "LCL 1.6.0.4",
ppu="C:\lazarus\lcl\units\x86_64-win64\win32\interfaces.ppu",
source="C:\lazarus\lcl\interfaces\win32\interfaces.pp"

Thank you.
