How to use external lib in MACOS app

Roy44

Hi,
I'm working on cross platform application.
So I develop with QT.
I am a newbie on MACOS.
Qt creator makes an .app application, so I call qtmacdeply in my post compilation script.
I use externals dylib I put in app via my script. But if I launch my application (without QtCreator)
it crash because it can't find image of my external dylib.
I tried to use install_name_tool command (seen in some forums) but it change nothing.
How can I fix this?
Thanks (sorry for my english)
That's my post compile script :

projectPath=$PWD
outputDir=$PWD/build/$1
applicationLibPath=$PWD/build/$1/MediaCad.app/Contents/Frameworks
applicationPath=$PWD/build/$1/MediaCad.app/Contents/MacOS
teighaModulePath=$PWD/tx/macx
teighaDylibDir=$PWD/bin/macx
occDylib=$PWD/bin/macx/OCC

#copie des modules tx
cd $projectPath
echo copy teigha tx
cp $teighaModulePath/*.tx $applicationPath

#copie des modules txv
echo copy teigha txv
cp $teighaModulePath/*.txv $applicationPath

#copie des modules mrx compilés
echo copy compiled mrx
cp $outputDir/*.mrx $applicationPath

#copie des modules txv compilés
echo copy compiled txv
cp $outputDir/*.txv $applicationPath

#copie des modules tx compilés
echo copy compiled tx
cp $outputDir/*.tx $applicationPath

echo copy extern files
cp -R $projectPath/ExternFiles/* $applicationPath

echo macdeploy
macdeployqt $outputDir/MediaCad.app


echo copy info.pList
cp $projectPath/Mediacad/Info.plist $outputDir/MediaCad.app/Contents

echo relink dylib
cd $applicationLibPath
compiledFileList=$(ls *.dylib)

echo copy teigha dylib
cp $teighaDylibDir/*.dylib $applicationLibPath

#relink dylib générés
for dylibFile in $compiledFileList
do
    for teighaLib in $teighaDylibFileList
    do
        install_name_tool -id $teighaLib $applicationLibPath/$teighaLib
        install_name_tool -change $teighaLib @executable_path/../Frameworks/$teighaLib $dylibFile
    done
done

cd $applicationLibPath
dylibFileList=$(ls *.dylib)

cd $applicationPath
moduleFileList=$(ls *.tx *.txv *.mrx)

#relink des modules tx mrx txv
for dylibFile in $dylibFileList
do
    for module in $moduleFileList
    do
        install_name_tool -change $dylibFile @executable_path/../Frameworks/$dylibFile $module
    done
done

Hi,

You should also change the dependencies id to something like @rpath/MyCustomLib.dylib

qtMacdeploy do this for my own compiled libray.
I try to do this for external library:

copy external library into myApp/Contents/Frameworks
do install_name_tool -id extenallib.dylib @rpath/externallib.dylib
But I have an error : can't open file @rpath/externallib.dylib (no such file or directory)
It depends on current directory (pwd) ?

I understand :
It's not install_name_tool -id extenallib.dylib @rpath/externallib.dylib
but install_name_tool -id @rpath/externallib.dylib extenallib.dylib
