When I attempt to build my project I'm getting the message:

C:\Photography\Software\Lazarus\rakphotography.lpr(6,28) Fatal: Can't find unit Interfaces used by rakphotography

When I attempt to run my project I'm getting the message:

If I Build Lazarus with my project open, I rebuilds to completion but my project still does not build or run.

If I Build Lazarus with no projects open I get the following message:

Did you add the LCL as dependency in the project inspector? Did you compile the LCL?
Are you cross compiling?
Did you try to compile with -vu -vt?

Maybe the program is still running? Windows locks executables during run.

You can not build startlazarus while it is running. And you don't need to.

Mattias

Mattias,

Yes the LCL is a dependency in the project inspector. Yes the LOL in compiled.
I am not cross compiling (although I'm not sure what that is) How do I compile with -vu -vt?

thanks,
bob k.

--------------------------------------------------

Good.

How do I compile with -vu -vt?

These are verbosity flag in the compiler options (Messages).

Mattias

Compiled with -vu -vt options:

--------------------------------------------------

Sorry. You misunderstood me.
To find the error 'unit interfaces not found' you should compile with -vt -vu.

The can not create object files means for example: disk full, no write permissions, output directory does not exist or output file is locked. Delete the old exe before compiling.

Mattias

Mattais,

I deleted the exe file, then selected Run. The project recompiled successfully, but now it says (debugging...) and is not doing anything else.

Hi Bob,

Lazarus use GDB (from the mingw project) for windows. Unfortunately I have not yet found a realty bug-free version of GDB.

I would advice to:
a) use the "reset debugger" entry from the "run" menu. (especially if you get error msgs running an app the 2nd time)
b) Check with the task manager for any gdb processes, that are left over. (That could also have cause your files to be locked)

Best Regards
Martin

Still the same problem.

--------------------------------------------------

Hi Bob,

I understand this as follows:
- Lazarus compiles, and a new exe is generated.
- the exe can be started from windows explorer, and works if your exe doesn't start from the win explorer neither, the below dbg questions are irrelevant.
- the exe does *not* open in a shell => it's linked as a win32-gui-app (compiler-options/linking)

1) What is the "debugger optins" (environment menu) setup on your lazarus? type should be "Gnu debugger", no ssh
path must point to a valid gdb.exe

2) What version of GDB?

3) If you open "view menu"/"debug windows"/"debug output" can you copy the content ?

Best Regards
Martin

Hi Martin,

1. lazarus/mingw/bin/gdb.exe
2. I'm unable to find the version of gdb.exe
3. there is nothing in the debug output window

the exe will not run from windows explorer.

I'm running Windows Vista.

--------------------------------------------------

the exe will not run from windows explorer.

Ah ok, so it's not a debugger problem. Does the above mean: 1- Windows says it is not a valid executable? => probably best to go to the fpc mailing list
2- Window claims you haven't got permission to run it? 3- Windows doesn't say anything

--> And just to be on the save side, compiling a simple new project with a form, does that get you a working executable? <--

Also worth checking in the compiler option, that you selected to produce a windows option, and for the correct cpu.... Best to reset all settings to their default.
Remove all optimizations / Enable All range, Stack etc checking. / Remove using a manifest

In case 3:

It looks like your exe either goes into an endless loop (check the process list/task manager), or crashes/exits it imported into lazarus, from Delphi or some other tool? -Does it use special libs that are not part of lazarus, freepascal, could they have initialization code?

In any case it will be hard to find, since you can't debug it from inside Lazarus (unless you are a GDB expert and can use GDB standalone).

You could try to remove features from the app, until you get a working executable. Then add them again, and see which one breaks it... But it's a lot of work, and no promise it will lead anywhere.

Best Regards
Martin.

Sorry if this isn't of much help, but I am purely guessing here. Good luck.
