Deploying my application with my own library is failed.

[Wunian]

Hi,
My environment is below,
Mac mini, MacOS M1 64bit, Sonoma 14.2.1
XCode: 15.2

I use Qt 6.5.3, and set target path as below,
unix {
target.path = /usr/local/lib
}

and create my own library, and build it in my release-build folder.

Next, I copy my library(libMymac.1.0.0.dylib) to /usr/local/lib,
and create symbolic-link files in the same path as below,
libMymac.dylib
libMymac.1.dylib
libMymac.1.0.dylib

I also create an application (Mymacapp), and load my own library in the pro file as below,
LIBS += -L$$PWD/Mymac/ -lMymac.1.0.0
and build my application, and it works fine.

Now, I try to deploy my application like this,
./macdeployqt Mymacapp.app

it complains <ERROR: no file at "/usr/lib/libMymac.1.dylib">.

Here my question is, I set target.path = /usr/local/lib,
why I get the error path /usr/lib ??

May I know how I can solve this issue?
Thanks.
Have a nice day.

@Wunian if memory serves well, you should append it to the QMAKE_RPATHDIR variable.

I guess the macdeployqt tool does not look in /usr/local/lib by default

Hi,

Check your library with otool -L and see what path it contains. You will likely not see /usr/local/lib. You should set it properly there.

As you said, "You should set it properly there".

I set target.path in pro file, but it doesn't work.
Thanks.

@SGaist
I set QMAKE_RPATHDIR += /usr/local/lib in pro file.
