and I also

by the way, Does my Qt install incorrect on Mac OS 10.15.3?

and finally works! 💆

I just luckily that anaconda have these QT dylib files. My question is Why Qt build from source can not have these dylib files, Do I need some special config for build QT for Mac OS ?

Riateche · 2020-03-16T16:27:39Z

Looks like the build script failed to detect that Qt is built in framework mode.

How did you build and install Qt? Is qmake corresponding to the installation added to the current PATH?

Please show output of these commands:

qmake -query
ls /usr/local/Qt-5.14.0/lib/QtWidgets.framework

tauruswang · 2020-03-18T07:22:29Z

I build my Qt from the source code repository.
After make finished, I do the make install.
It seems to install all the built output files to /usr/local/Qt-5.14.0/

Actually I run the qmake -query, it is output
(base) JerryWs-MacBook-Pro:redox jerryw$ qmake -query

And my build version is at /usr/local
ls /usr/local/Qt-5.14.0/lib/QtWidgets.framework
Headers QtWidgets QtWidgets_debug Resources Versions

I guess, the PATH environment lets qmake find Qt Library from Anaconda stuffs.

echo $PATH
-bash: export: /Users/jerryw/anaconda3/bin:/Users/jerryw/anaconda3/condabin:/usr/local/opt/qt/bin:/Users/jerryw/.cargo/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/opt/local/bin:/opt/local/sbin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/VMware': not a valid identifier -bash: export: Fusion.app/Contents/Public:/opt/X11/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Users/jerryw/.rvm/bin:/Users/jerryw/Library/Android/sdk/tools:/Users/jerryw/Library/Android/sdk/platform-tools:/usr/local/opt/go/libexec/bin': not a valid identifier

and my PATH environment also looks not correct ...

Riateche · 2020-03-18T12:49:14Z

The qmake executable should point to the Qt installation you're trying to use. To achieve that, change your PATH variable:

export PATH=/usr/local/Qt-5.14.0/bin:$PATH

You should also set DYLD_FRAMEWORK_PATH to allow dyld to find the frameworks at runtime:

export DYLD_FRAMEWORK_PATH=/usr/local/Qt-5.14.0/lib:$DYLD_FRAMEWORK_PATH

tauruswang · 2020-03-20T07:24:03Z

Yes, after I set these environment variables.
export PATH=/usr/local/Qt-5.14.0/bin:$PATH
export DYLD_FRAMEWORK_PATH=/usr/local/Qt-5.14.0/lib:$DYLD_FRAMEWORK_PATH
but it still doesn't work, and said dyld: Library not loaded: @rpath/libQt5Widgets.5.dylib
I just wondering, Do I need to recompile the Qt source code that makes sure these dylib files carry-out in DYLD_FRAMEWORK_PATH, then will works?

Riateche · 2020-03-21T19:56:12Z

Have you tried running cargo clean before building again with these environment variables?

Are you able to build and run C++ Qt projects (e.g. examples bundled with Qt) using this Qt build?

Nick011 · 2020-05-04T02:41:05Z

dyld: Library not loaded: @rpath/libQt5Widgets.5.dylib

I just struggled with this same error for a few hours. I finally figured something out. Try this:

Create a file in your project .cargo/config
Put the following in there:

[build]
rustflags = ["-C", "link-args=-Wl,-rpath,/usr/local/Qt-5.14.0/lib"]

Make sure /usr/local/Qt-5.14.0/lib actually contains the Qt libs. I'm on Mac and my Qt libs are installed at /Users/nick/Qt/5.14.2/clang_64/lib

I can now do cargo run and import a Qt lib without error. Now onto the next step of actually trying to use it.

Man, you have just saved me.

gavrilikhin-d · 2024-01-27T15:54:19Z

Why rust even generates dependencies with @rpath? I had an issue with @rpath/libc++.1.dylib
