Finding Qt5 on OS X with homebrew #27

Open ahundt opened 9 years ago

ahundt commented 9 years ago

I don't need this at the moment but wanted to record the issue.

I have Qt5 installed on OS X using homebrew, but the cmake configuration script failed to find it.

 Looking for Qt5: can't find Qt5Core
 Looking for Qt5: can't find Qt5Widgets
 Looking for Qt5: can't find Qt5Gui
 Looking for Qt5: can't find Qt5OpenGL
brew info Qt5
Qt5: stable 5.4.2 (bottled), HEAD
Version 5 of the Qt framework
https://www.qt.io/

This formula is keg-only.
Qt 5 conflicts Qt 4 (which is currently much more widely used).

/usr/local/Cellar/Qt5/5.4.1 (6392 files, 289M)
  Poured from bottle

==> Caveats
We agreed to the Qt opensource license for you.
If this is unacceptable you should uninstall.

This formula is keg-only, which means it was not symlinked into /usr/local.

Qt 5 conflicts Qt 4 (which is currently much more widely used).

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/Qt5/lib
    CPPFLAGS: -I/usr/local/opt/Qt5/include

.app bundles were installed.
Run `brew linkapps Qt5` to symlink these to /Applications.
``

all the folders seem to be correctly present in the standard `/usr/local/include` location:

ls /usr/local/include/Qt QtCore@ QtHelp@ QtScript@ QtTest@ QtXmlPatterns@ QtDeclarative@ QtMultimedia@ QtScriptTools@ QtUiTools@ QtDesigner@ QtNetwork@ QtSql@ QtWebKit@ QtGui@ QtOpenGL@ QtSvg@ QtXml@

Note: Qt5 seems to be found automatically if installed via MacPorts.

However, it seems like Qt5 is a required dependency now, as I haven’t succeeded to generate the cisst project without installing it first. I had Qt4 installed but that was irrelevant, as CMake didn’t let me generate unless I had Qt5. This happened on two different computers (both OS X with Xcode) in the past week using up-to-date cisst source.

The solution was to remove Qt4 and install Qt5, but that’s not a desirable behavior. Cisst should be able to compile without any Qt available.

I just updated my MacPorts and cmake does not find qt5-mac @5.4.2_1 on OS X. I can manually point cmake to each QT module which works.

Looks like mac ports is starting to install qt5 in a different directory so that it does not conflict with qt4:

When I wanted to install Qt5, it returned with an error saying that Qt4 needs to be uninstalled before installing Qt5.

How do we use qtlua with Sierra? I can't find an easy way to install Qt4 on Sierra.

ericalingyuan commented 7 years ago

@pratheeksh me neither. spend two days. just try to figure out how to install qtlua on mac, qtlua require qt4.x, but cannot install qt4.x on current mac

ahundt commented 7 years ago

qt4 is end of life with no support. It is not recommended you use it. That said, the following should install it from https://github.com/osrf/homebrew-simulation:

brew tap osrf/simulation
brew install qt4-no-webkit

as for qtlua perhaps ask them? https://github.com/torch/qtlua

or maybe use luarocks? https://luarocks.org/
