    Default QtCreator project with libs, apps. Deployment to end user.

    Hi,

    My setup: QtCreator 2.6.2, Qt 5.0.1, Linux slackware 32bit (current).

    I'm trying to setup my QtCreator (or "pro" file?), so I can build application which has 1 shared library and 2 applications - both linking dynamically to that library. I've created Subdirs project, added library project, added 2 application projects, everything builds fine and runs fine under QtCreator.

    Problem is that when the time comes and I'd like to prepare package for end users I need to have directory structure somehow like:
    Qt Code:
    1. MyApp/
    2. lib/
    3. App1
    4. App2
    To copy to clipboard, switch view to plain text mode 
    and the problem here is that linker won't see those libraries. One solution is to add ./lib to LD_LIBRARY_PATH, but 1) this is not very nice solution, requires scripts for running the app, 2) it's not portable and I want to deploy my App to windows and mac in future.

    How should it be done? How to tell QtCreator to create application binaries which point to specific relative path, regardless of platform? I assume that for final "Release" configuration I would have fixed directory structure and I can provide fixed relative paths for libs.

    How to tell QtCreator to create application binaries which point to specific relative path, regardless of platform?
    I guess relative to the path containing the .pro file.
    Qt Code:
    1. # this will create the binary in the .pro file path
    2. DESTDIR = $$_PRO_FILE_PWD_
    To copy to clipboard, switch view to plain text mode 
    When you know how to do it then you may do it wrong.
    When you don't know how to do it then it is not that you may do it wrong but you may not do it right.

    EDIT:
    Forget below. Just found http://qt-project.org/doc/qt-5.0/qtdoc/deployment.html Thread can be closed.


    No, I don't mean "how to tell where to create binary". I mean "how to tell the binary application where is the library placed in relative position to the application binary" - in a portable way.

    EDIT:
    In other words:
    Is there a way to define in qmake, that my "App1" should look for dynamically linked libraries in a subdirectory "./lib/"?

    I want to be able to build on unix:
    Qt Code:
    1. App/
    2. lib/
    3. libapp.so
    4. app1
    5. app2
    To copy to clipboard, switch view to plain text mode 
    and on windows
    Qt Code:
    1. App\
    2. lib\
    3. app.dll
    4. app1.exe
    5. app2.exe
    To copy to clipboard, switch view to plain text mode 
    by just defining "app" library to be a dynamically loaded library in app1 and app2 binary applications.
