Hi,

After getting the recent trunk version of Laz and FPC, using fpcUP, there is an error whenever rebuilding was attempted:

singleinstance.pp(74,12) Fatal: Can't find unit singleinstance used by
CustApp

And the pointer is at this line, not sure what is wrong:

property OnServerReceivedParams: TSingleInstanceParams read
FOnServerReceivedParams write FOnServerReceivedParams;

And there is a warning before that:
Warning: Recompiling singleinstance, checksum changed for AdvancedIPC

This error appeared with the tagSize/TSize issue that was recently discussed and solved. Before that it was not there.

Win 8, Laz1.5, FPC3.1.1

Thanks

Jamal

Try to clean build.

And before Clean&Build update your Lazarus trunk.

Ondrej

Run -> Clean up and Build ...

Still persist.

Do you have the problem when compiling a custom application or Lazarus IDE?

If Lazarus IDE: Tools -> Configure "Build Lazarus" -> Clean Up -> Clean All.

Ondrej

There is no problem compiling a custom application. The problem only within Lazarus IDE.

When I do:
Tools -> Configure "Build Lazarus" -> Clean Up -> Clean All

I get:
custapp.pp(21,23) Fatal: Cannot find singleinstance used by CustApp. Make sure all ppu files of a package are in its output directory. ppu in wrong directory=C:\development\fpc\units\i386-win32\fcl-base\singleinstance.ppu..

First, do "make clean all" with your FPC trunk, then the same with Lazarus IDE (or run Clean All&Build Lazarus from the IDE).

Ondrej

make clean all with fpc is successfully done, but with lazarus, there is the same error:

(10001) PPU Loading

You still have an old advancedipc.ppu.

Tools / Configure Build Lazarus / Clean up / Clean all.

Then build.

Mattias

Tools / Configure Build Lazarus / Clean up / Clean all. Then build.

Tried that already, but Lazarus unable to complete rebuilding. It errors out as per the attached screen shot:

Then don't use trunk versions, use stable versions instead (FPC 3.0 and Lazarus 1.4).

Ondrej

I use Last stable release side by side with Laz1.4.4+FPC3.0.1 (last fixes). Only wanted to have trunk available as well.
Anyways, Thank you Ondrej and Mattias.

Regards.

Build Lazarus trunk with FPC 3.0.*. You won't have this problem.

Ondrej

Build Lazarus trunk with FPC 3.0.*. You won't have this problem.

How to do that?
Tried changing the fpc dir and make Laz1.5 points to fpc3 but that did not work. How to build laz1.5 with fpc3.0?

Set "Tools / Options / Files / Compiler executable" to the new compiler (fpc.exe).
Then build.
