Installing Qt/qmake via brew

Environments macOS
1

I can’t get brew to correctly install qmake on macOS. I’ve tried to install the qt and qt5 formulae and the qt-creator cask, plus I ran brew link qt5 --force as suggested by this link, but none of these things worked.

The qt formula is keg-only, so you need to use full paths to access its stuff. Qmake is at /usr/local/opt/qt/bin.

Since it’s keg-only for a reason (specified in the Caveats section), avoid linking it unless you’re ready to face the consequences.

$ brew install qt
<...>
==> Caveats
<...>

qt is keg-only, which means it was not symlinked into /usr/local,
because Qt 5 has CMake issues when linked.

If you need to have qt first in your PATH run:
  echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.zshrc

For compilers to find qt you may need to set:
  export LDFLAGS="-L/usr/local/opt/qt/lib"
  export CPPFLAGS="-I/usr/local/opt/qt/include"

For pkg-config to find qt you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/qt/lib/pkgconfig"

$ ls /usr/local/opt/qt/bin

Running that, followed by source ~/.zshrc, fixed my problem.

Thanks!
