Library not found on Mac OS

[SGaist]

What version of Qt are you using ?

How did you call macdeployqt ? Also where did you call if from ?

What version of OS X are you using ?

[Amott]

I use Qt 5.7. I called macdeploy like that :

/Users/developpement/Qt/5.7/clang_64/bin/macdeployqt MediaCad.app

and I the output is :

ERROR: no file at "/usr/lib/libMdCore.1.dylib"
ERROR: no file at "/usr/lib/libMdWidgets.1.dylib"
ERROR: no file at "/usr/lib/libMdModels.1.dylib"

I call it from my .app directory.

I have tried to call it with -verbose=3 and here is the output : http://textup.fr/172668xw

I'm using OS X 10.11.5

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.
