[Solved] Qt on Mac: set the path to find out *.dylib, when run under debug mode.

[szuzsq]

I have a test project at:
@
$${some_path}/
@
it depend upon a dylib at:
@
$${some_path}/lib/b.dylib
@
and it generated at:
@
$${some_path}/bin/test.app
@

when I cd to
@
$${some_path}/bin/test.app/Contents/MacOS
@
and run otool:
@
otool -L test
@
It ask for
@
./lib/b.dylib (compatibility version 52.0.0, current version 52.122.0)
@

so, I must copy
@
$${some_path}/lib/b.dylib
@
to
@
$${some_path}/bin/test.app/Contents/MacOS/b.dylib
@

My problem is: How can do? If I don't want to copy the *.dylib, and also to fix the test.app with
@
install_name_tool
@
Is any way find upon b.dylib, when run debug mode in QtCreator?

[szuzsq]

Some times, we have project "test.app" depend upon to "b.dylib".
But after rebuild "b.dylib", we forget to copy "b.dylib" to "test.app/Contents/MacOS/"

In msvc2008, we can set the "porject dependencies"
So, when we try to build porject "a", and the IDE check project a is depend upon project "b", and find some source code of project "b" has been edited,
in this situation, the IDE build project "b" first and then build project "a".

I think, that is a good solution.
But in Qt:
@
#all.pro*
TEMPLATE = subdirs

SUBDIRS += test
SUBDIRS += b
@

1. I don't know how to set project "test" depend upon to project "b"?
2. When I run debug "test" project, how to set QtCreator to find out "b.dylib" in itself's output path, but don't need to copy "b.dylib" to "test.app/Contents/MacOS/"?

Before running your program you can set the following path variable:
'export DYLD_LIBRARY_PATH=$${some_path}:$DYLD_LIBRARY_PATH'

Your application will look for its dependencies in the PATHs set in this colon-separated variable.

Check the dyld manpages for more information: 'man dyld'

Have a look into install_name_tool, you can change the path to the library with that one. The "Mac Deployment Guide":http://developer.qt.nokia.com/doc/qt-4.7/deployment-mac.html has some examples.

Volker, that's precisely what he is trying to avoid from what I understand! It's for debug purposes.

[szuzsq]

Yes, thanks all.
I add the variable in page "Projects/Run Settings/Run Environment":
DYLD_LIBRARY_PATH=$${some_path}:$DYLD_LIBRARY_PATH

Well, I guess you can mark the topic as solved then :)

Just go to the very first post in this thread and click the edit link on the right (just below your avatar and username). And add "[Solved]" to the topic. You can add a tag "solved" too (but others might be quicker with that :-) )
