linking qwt problem - mac os

maximus

When building my main app, my application links to qwt
I need qwt and would like it to be linked correctly like other Qt frameworks.
I rebuilded qwt 6.1.3 with 5.8.0, put the resulting .framework in /Library/Frameworks and also in qtInstallFolder/lib

Here is the part linking qwt in my .pro

   QMAKE_LFLAGS += -F/Users/tourlou3/Dropbox/qwt-6.1.3/lib
   LIBS += -framework qwt
   INCLUDEPATH += /Users/tourlou3/Dropbox/qwt-6.1.3/src

Every time I rebuild, I have to change my executable with install_name_tool before deploying, since the path of the qwt link is wrong

Here are the libs linked to my app using otool -L

Also note that I am having this error while using macdeployqt:
ERROR: no file at "/Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/qwt"

There is indeed my library located in /Library/Frameworks/ so I don't understand why it fails there.

So after each build, I have to manually copy the library "qwt.framework" inside my Content/Frameworks and run install_name_tool
install_name_tool -change qwt.framework/Versions/6/qwt @executable_path/../Frameworks/qwt.framework/Versions/6/qwt /Users/tourlou3/build-PowerVelo2-Desktop_Qt_5_8_0_clang_64bit-Release/MaximumTrainer.app/Contents/MacOS/MaximumTrainer

Anyone ran into this problem? Cheers,
Max

/Library/Frameworks/qwt.framework

Can you post the output of find /Library/Frameworks/qwt.framework and as for the library it may resolve with the macqtdeploy starting to work, otherwise you may need to run otool on your libs themselves setting it to use a relative rpath, then it will work even on a raw copy without otool intervention.

Most of my deploys for my commercial apps on OSX I end up with quite large bash shell scripts that run the otool stuff I need on the dependency libs.

I find it's easier than constantly fighting macdeployqt and it assures me that my application will definitely be deploy ready instead of relying a tool that has failed me many times in the past.

The weird think in the macdeployqt error is this part

ERROR: no file at "/Library/Frameworks/qwt.framework/Versions/6/qwt.framework/Versions/6/qwt"
The library is in /Library/Frameworks/qwt.framework/Versions/6/qwt"

It seems like some kind of recursive dependency, qwt.framework inside qwt.framwork?

5.8.0 seems to have fixed most of the bug that I had with macdeployqt from 5.5 to 5.7.1.
Usually I am fine deploying with it without too much hassle.

@maximus Yea it looks like the macdeployqt tool was, for lack of a better term, greping your otool output incorrectly so it formed the wrong path for that qwt framework. Including the qwt.framework/* section twice.

Good to know that 5.8 fixed the problem though. It may have just been a bug in the earlier macqtdeploy. Those are the bugs I've come to expect from the macqtdeploy app and the reason I stopped using it for the most part. :)

Yeah I guess macdeployqt generate a wrong path like you said, just don't know why it happens only for this framework in particular..

I always struggle deploying on mac, wish there was an easy way to deploy and speed up packaging for new releases.
For now I will use macdeployqt + a few command line to fix this bug.
Thanks for the help

I give up on qwt.
I tried editing the framework path to permanently fix it but was not successful.
install_name_tool doesn't change it to @rpath/.. for some reason.

Lol yea that is what I do.. In the end I even dropped using macdeployqt entirely.

I thought about writing an open source project that helps easily deploy on osx but I just haven't had the time to do it. Deploying on OSX has so many things that it needs that even writing an automated app is daunting.

I mean essentially that is what macdeployqt is, and well, you see that doesn't always work. ;)

ambershark

@maximus Have you done the -id part of the otool?

otool -id @executable_path/Frameworks/qwt.framework/Versions/6/qwt Frameworks/qwt.framework/Versions/6/qwt

Then:

otool -change /Library/Frameworks/qwt.framework/Versions/6/qwt @executable_path/Frameworks/qwt.framework/Versions/6/qwt /path/to/your/binary

This is for your actual binary though, not to fix it permanently. This would be run before deploy each time.

maximus

Yes it is working for my app binary.
I tried changing the qwt reference to itself and adding "@rpath/.." so I don't have to do this over and over again.
Will try that on the qwt library tonight, forgot the -id part, probably why it was not changing.

I would be happy to get a tool that just change the path of ALL my depending libs to @rpath/[name_of_lib]
in my Qt .pro file, I already set my @rpath to the locations relative to the executable I want to look at runtime.
