Library not found on Mac OS

SGaist

Ok try with:

Add

QMAKE_LFLAGS_SONAME = -Wl,-install_name,@rpath/

to your libraries .pro file

and

QMAKE_RPATHDIR += /path_your_libs_dir/

to your application .pro file

Amott

So, I tried that but I still got the same error with macdeploy and the same exception in my app. Maybe I did it wrong :
I add QMAKE_FLAGS_SONAME = -Wl, -install_name, @rpath/
and in my app .pro : DEPENDPATH += ../debug

I have tried to change the first one into QMAKE_FLAGS_SONAME = -Wl, -install_name, ../debug/ but still the same thing.

The exception is about RecomputeDimBlock.tx, which is not a lib from me, so I can't apply anything to it

SGaist

Why DEPENDPATH ? It's not the same thing as QMAKE_RPATHDIR .

Also, I'd rather try with the full path using the OUT_PWD variable with QMAKE_RPATHDIR

Amott

I just copy/paste the wrong line, I have tested with QMAKE_DIRPATH.
It didn't change with OUT_PWD.
Maybe there is a thing to do with command install_name_tool on all library ? I will take a look on this trail

SGaist

Again, it's not QMAKE_DIRPATH, it's QMAKE_RPATHDIR

Amott

erf... I should go back to school and learn to read again !
so now I have : QMAKE_RPATHDIR=OUT_PWD/../debug
but, nothing has changed

SGaist

Did you forgot the double $ before OUT_PWD?

Amott

Oh... Yes... It explains why it didn't work !
The command macdeploy now works fine ! A lot a thing appeared in the .app. But the .tx is still not detected even after copying it on the right directory

SGaist

Can you remind me what these .tx files are ?

Amott

In my case .tx is a lib provided by ODA library.
When my app start, I use a function "loadapp" from ODA, to load my .tx. After debugging it seams that this function is looking for the tx into <myapp.app>/Contents/MacOS directory, so I placed my lib here but it still doesn't detect it

SGaist

macdeployqt won't handle them because it currently only targets .framework and .dylib.

If we want to nitpick, putting "plugin" in the MacOS folder is wrong from a bundle point of view.

You have to write a script that copies these .tx file at the right place and call install_name_tool on them to update the paths to all their dependencies (excluding the system libraries)

Amott

ok so if I understood correctly, I have to write a script that first build my .app, then copy the .tx into MacOS and finally apply install_name_tool ?

SGaist

Not necessarily. I was more thinking about a post-macdeployqt script that would handle the .tx files.

Amott

ok, given that I'm an intern and my internship will end next week, I prefer writing a bash script that makes everything, that will be easier for my workmate in the future.
Is there anyway to tell Qt that it has to call this script after compiling ?

SGaist

What do you mean by everything ? Run macdeployqt or build your application + macdeployqt + .tx deployment ?

Amott

Yes, after compiling, the script calls macdeployqt, and install every tx properly, the application should work after that (I hope).
For the moment I just call macdeployqt and copy every tx into MacOS.

SGaist

It's been a long time since I've done this but IIRC you should be able to do that adding a custom target.

See qmake's adding custom targets documentation.

Amott

Thanks for your help ! I will take a look a that, and post another thread if I have a lot of problems.
