How to tell qmake copy third-party framework to DEST_DIR(.app/Contents/...) on OS X?
-
Yes
install_name_tool, allows you to alter the paths of the dependencies of your application or library. That allows you to embed frameworks/libraries etc. in your bundle and make your application find them. e.g. @executable_path means that the dependency is found in the same folder as the executable.
-
Well, I kind of get it, but I can't get it to run even without playing with install_name_tool, so that's where my confusion comes from.
I built the app, and let's say it's in ../bin/myapp.app
the @executable_path is myapp.app/Contents/MacOS/
After getting that message on trying to run my app, I thought I'd just copy the CEF framework into the Contents/MacOS/ , and so I did.
But I still cannot run it with the same mistake. Is there any reason that could happen?
otool -L myapp gives:
@executable_path/Chromium Embedded Framework (compatibility version 31979.8.123, current version 31979.8.123)
otool -L Chromium\ Embedded\ Framework gives:
@executable_path/Chromium Embedded Framework (compatibility version 31979.8.123, current version 31979.8.123) -
Finally made it work by changing the path to C E F.framework/C E F (did not understand that I have to "go inside .framework" for a while) for myapp.app
Thanks for the help! )
Will try to figure out how to properly do it now. -
Usually macdeployqt would do that for you. You can also write your own script that call install_name_tool
-
Yeap, ended up writing the script for this. Have another question if you don't mind:
The script currently runs when qmake runs (which is not good), I wanted to add it to QMAKE_POST_LINK, and it worked great when I only needed the path to script, but then I had to pass my script an argument so I ended up using the system() function of qmake.
And it didn't work well, was giving me errors, but worked fine when I removed the QMAKE_POST_LINK +=
Anyway, do you have an idea of why something like
QMAKE_POST_LINK += system($$PATH_TO_SCRIPT $$SCRIPTARG)wouldn't work and leaving onlysystem($$PATH_TO_SCRIPT $$SCRIPTARG)does?[edit: added coding tags around pro file code SGaist]

You should use two $ signs when you want to get the content of a variable
-
Yes, I was doing that, I think when I posted my message the other ones were cut off. So it should work this way? I don't know what might be the problem. $$
-
Ok, just remembered: QMAKE_POST_LINK should contain command(s) for the shell in a similar way you would write in a Makefile. So is your script executable ?
-
Sorry, I'm not big on scripts and the terminology there, it's just a .sh script with a series of commands, like cd [folder] , install_name -change [bla-bla] etc.
To make it executable I should return some value at the end or ..?
The error I get is:
"/bin/sh: -c: line 0: syntax error near unexpected token `"path/to/script"'I also tried QMAKE_POST_LINK += system(sh $$ARG1 $$ARG2) to no avail
-
chmod +x name_of_your_scriptto make it executable.QMAKE_POST_LINK += $$quote($$ARG1 $$ARG2)should do the trick -
Thank you, turned out it could be done like this:
QMAKE_POST_LINK += $SCRIPT_PATH $ARG1 $ARG2
No need for system()
