Strange Lazarus 1.4.0 problem on OS X causing debugger error
lazarus / 12-Debugger

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

Not sure if this is IDE configuration or debugger issue:


I am getting an odd error every time I try run my application from
within Lazarus:

Quote"Debugger error.... Stop and hope for he best, we're pulling the
plug'
message (not exact words but close)

In details I get this:

QuoteFailed to load application execuable

"/Volumns.../path/mylazarus.app/Contents/MacOS/mylazarus": not in
executable format: File format not recognized

Here comes the kicker though... If I move the core executable file 
"mylazarus" into my own .app file it runs fine without problems.

Any ideas what I can try check? Configuration, tests or similar?

So far unsuccessful at resolving the problem - trying different things
right now like recreaing the project etc. Here's debugger log

Right now, it acually appear to have been improved - but this is very
preliminary (!)

I went into "Run | Run Paramaters...." and in "Host application"
passed it:
/Volumes/DiskW/projects-cool/MyProject/compiled/MyProjectLazarus (i.e.
the core executable)

Runtime, I have code that checks for data files using multiple test
paths (if running in or ouside .app) after which it adjusts

I am slightly puzzled as to why my solution works though... Since I
would expect Lazarus to "autofill" this path in. "Host application"
was empty before I filled in the path.

However, on the downside, my app can not gain focus... (i.e. can'
select any control with the mouse or anyhing) so as such, I am only a
little closer to a solution
