Running the program on OSX fails

[Igor Korot]

Hi, ALL,

I built libmysqlclient from sources on my Apple laptop. Everything built fine.

Then I built my program that will be using this on the same laptop. The build succeeded. I'm using the Xcode to build my program

In the end of the build it runs following command:

    cp -f ~/dbhandler/dbhandler/mysql-server/BuildOSX/libmysql/libmysqlclient.dylib "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/libmysqlclient.dylib"
    
    install_name_tool -id "@rpath/Frameworks/libmysqlclient.dylib" "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/libmysqlclient.dylib"
    
    cp ~/dbhandler/dbhandler/Build/Products/Debug/liblibmysql.dylib "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/liblibmysql.dylib"
    
    install_name_tool -id '@rpath/Frameworks/liblibmysql.dylib' "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/liblibmysql.dylib"
    
    install_name_tool -change "/Users/igorkorot/dbhandler/dbhandler/mysql-server/buildOSX/libmysql/libmysqlclient.21.dylib" @executable_path/../Frameworks/libmysqlclient.dylib "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/liblibmysql.dylib"

    install_name_tool -change "/usr/local/lib/liblibmysql.dylib" @executable_path/../Frameworks/liblibmysql.dylib "$TARGET_BUILD_DIR/$TARGET_NAME.app/Contents/Frameworks/liblibdbloader.dylib"

so that the library can be used from inside the Bundle.

When verifying, I have the following:

    Igors-MacBook-Air:Frameworks igorkorot$ otool -L liblibmysql.dylib 
    liblibmysql.dylib:
    	@rpath/Frameworks/liblibmysql.dylib (compatibility version 1.0.0, current version 1.0.0)
    	@executable_path/../Frameworks/libmysqlclient.dylib (compatibility version 21.0.0, current version 21.0.0)
    	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0)
    	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.50.4)
    Igors-MacBook-Air:Frameworks igorkorot$ otool -L libmysqlclient.dylib 
    libmysqlclient.dylib:
    	@rpath/Frameworks/libmysqlclient.dylib (compatibility version 21.0.0, current version 21.0.0)
    	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0)
    	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.50.4)
    Igors-MacBook-Air:Frameworks igorkorot$ pwd
    /Users/igorkorot/dbhandler/dbhandler/Build/Products/Debug/dbhandler.app/Contents/Frameworks
    Igors-MacBook-Air:Frameworks igorkorot$

As far as I understand the "otool" output - everything is linked to the place inside the Bundle.

However when I tried to run my application (from Terminal with "open dbhandler.app"), I get the following error:

Quote

Failed to load shared library liblibdbloader.dylib
dlopen(liblibdbloader.dylib, 2). Library not loaded: /usr/local/lib/liblibmysql.dylib.
Referenced from
Reason: image not found

The dbloader.dylib library had been re-linked to the libmysql that was copied to the new place (and otool seems to confirm that):

So what am I missing? Could someone look at that?

I'm not sure what else do I need to do in order to have successful run...

Thank you in advance.
