[Split] Mac deployment problem using zLib

  • Hi marksutton,

    I'm facing a similar problem when trying to deploy my qt windows application on mac os x 10.6.8 (64 bit).

    I tried to deploy using the automatic deploy tool (macdeployqt) and i am able to run the resulting "". However, at some point of the application an external library is used to process vnc features, and that library apparently uses libz.1.dylib, and it causes an application crash:

    Exception Type: EXC_BAD_ACCESS (SIGSEGV)
    Exception Codes: KERN_INVALID_ADDRESS at 0x00000000ffafd8f2
    Crashed Thread: 7

  • [I've split your question off from the "older thread":/forums/viewthread/5934/ where your posted it originally.]

    Does your application work without using macdeployqt?

  • Hi Volker,

    Thank you for your quick response. My application works without macdeploy, but in order to run my application from Qt Creator i needed to paste the necessary libraries in the MacOs directory that is inside the application bundle.

    I tried a different aproach and managed to deploy my qt application successfully (at last!). What i did was:

    1. Added CONFIG-=app_bundle , so qt creator won't create an application bundle
    2. Copied my resulting executable file into a new folder
    3. Copied all Qt frameworks and plugins into that folder (cp -R /Library/Frameworks/Qt* and cp -R /Developer/Applications/Qt/plugins)

    Now i can run my application without having qt installed. My next step is to somehow create an application bundle with this. I've searched a bit, and found Platypus, but haven't tried it yet.
    I was wasting a lot of time trying to solve problems with qt generated bundle and macdeployqt, so i dropped that solution.

    How can i "bundle" this solution (executable) into an application bundle? Do you know any good tools or programs to do so?

    Thanks in advance,


  • Go with the application bundle that's created by qmake. Everything else will do basically the same, so this won't save you anything.

    You can try to use macdeployqt to do the basic installation and tweak the rest afterwards. Or you copy the stuff by hand and run install_name_tool manually. Always copy all frameworks and libs that are not present on the default OS installation.

    As we do not know more about your application and its needs, I cannot comment more specifically.
