[Interest] Deploying on Mac permissions and automation

Hi,

I had this happening with homebrew's Qt as-well. Perhaps it is because homebrew sets the owner of the Qt files to root (but not 100% sure). Anyway although it is great that homebrew ships Qt, I would not suggest deploying applications with their Qt binaries. It may result in a package that won't run on lower versions of OSX than your development machine has, because of a high "macosx-version-min" (happened to me).

Using a binary Qt package or building Qt yourself with a low macosx-version-min is safer, and won't require sudo for macdeployqt.

Br,
Alessandro

Subject: [Interest] Deploying on Mac permissions and automation

Dear all,

I am experimenting with MacOS X (Qt 4.8.5), and I am finding it quite
unusual. The application is built by Xcode, and Qt comes from homebrew.

The first question: does macdeployqt need special permissions? If I run
it as a standard user, I get errors, if I sudo it, everything is fine:

However, with sudo it works:

Second question, related to the above: why isn't install_name_tool
working? Starting the application on a vanilla computer I get the
ominous error "Library not loaded: /usr/local/Cellar...", which is
referenced from QtGui inside my app bundle.

In the above log, I see that QtCore is tentatively installed with a
relative path:


Log: Deploying Qt frameworks found inside:
("MyApp.app/Contents/MacOS/MyApp")
Log: Using install_name_tool:
Log:  in "MyApp.app/Contents/MacOS/MyApp"
Log:  change reference "/usr/local/lib/QtCore.framework/Versions/4/QtCore"
Log:  to
"@executable_path/../Frameworks/QtCore.framework/Versions/4/QtCore"
Log:  copied: "/usr/local/lib/QtCore.framework/Versions/4/QtCore"
Log:  to "MyApp.app/Contents/Frameworks/QtCore.framework/Versions/4/QtCore"



So, actually I'd expected not to have the error.

Am I doing something wrong? Am I misreading the log?



Thanks!
