Hi,

I'm getting
"componenttreeview.pas(41,18) Fatal: Can't find unit ComponentTreeView used by ObjectInspector"

On this computer (win32, XP) rebuilding Lazarus does not work. Steps:

1. Clear all lazarus/fpc directories (except the c:\pp\bin\i386-win32\ so there's a working FPC compiler left to build again, included in the PATH global environment variable)
2. Check out FPC from SVN (or svn update) into c:\fpc_svn\
3. cd c:\fpc_svn\ , make clean, make all, make install works OK
4. Check out Lazarus from SVN (or svn update) into c:\lazarus_svn\
5. cd c:\lazarus_svn\ , make clean, make all, make install works OK
6. Start up Lazarus
7. Tools -> Build Lazarus produces the above error

Therefore cannot add any packages.

in the Environment options
Lazarus Directory = c:\lazarus
Compiler path = c:\pp\bin\i386-win32\fpc.exe
FPC Source dir = c:\fpc_svn\

Seems to be something like
http://bugs.freepascal.org/view.php?id=10433

Any thoughts?

At first sight I would say that the path to the ComponentTreeView is simply not set.

Without more info it's hard to tell. You would need to supply more of the error message, for instance why does the compiler want to recompile the ComponentTreeView unit ? Did it compile it before or not ?

Hi Michael,

Yes it was compiled when "make all" was called the first time, because c:\lazarus\ideintf\units\i386-win32\ contains componenttreeview.ppu and componenttreeview.o and both has the same date/time as all the other units there (obviously, because all of them were created with the "make all" command at once in step 5).
That is why it is very strange why this is happening. It is a totally clean svn checkout and compilation, and without doing anything within Lazarus, Im just trying to do a Tools->Rebuild Lazarus from menu after Lazarus is first started. Of course, I got the error originally when tried to add a package so I tried to track back what the problem is.
But even with a clean FPC/Lazarus SVN checkout and build this problem is there.

I have no idea why it wants to recompile this unit, when nothing changed, no packages added or removed, its just a simple rebuild Lazarus from the Tools menu after a clean install.

That's why you need to turn on more verbose messaging (-u -t), normally the compiler tells you why it wants to recompile a unit.

Michael.

Not sure that I did it right but attached are 2 screenshots as well as the original "make all" "make install" log from Lazarus compilation. The c:\lazarus\ideintf\units\...\ contains the compiled componenttreeview files after "make install"

I was guessing I need to put " -u -t " into the
Configure Build Lazarus dialog into the "Options" field (screenshot 1)

And the second screenshot is what I see after the error comes.

Use copy all (including hidden) message from the message view and attach that.

Have you checked that the IDE uses the right lazarus directory in the Environment Options?

Thank you for the help guys,

The message view content with hidden messages attached (laz-tools-rebuild.txt).
Here is the end of it:

PPU Loading C:\lazarus\ideintf\units\i386-win32\componenttreeview.ppu PPU Source: componenttreeview.pas not found
File C:\lazarus\images\componenttreeview.lrs is newer than PPU file C:\lazarus\ideintf\units\i386-win32\componenttreeview.ppu PPU Source: C:\lazarus\images\componenttreeview.lrs time 2009/02/17 13:14:08 *
componenttreeview.pas(41,18) Fatal: Can't find unit ComponentTreeView used by ObjectInspector

The two directories mentioned above is attached (laz-ideintf.txt and lazarus-images.txt)
However, the ppu file date is 02/19/2009 00:47 which is not older than the lrs file 02/17/2009 13:34

I attached the enviroment options dialog screenshot too for Mattias.

Also I can assure you guys that there are no hidden lazarus or ppc files anywhere on this computer, it was a totally clean install, and svn checkout for FPC then Lazarus. Then both compiled and installed. Then Lazarus fired up and hit the menu Tools->Build Lazarus.
