macOS Qt5 plan and status

[f3nix]

Hi Mateusz, On a Mac with a non-HiDPI display, the Qt5 build looks normal and the unit tests results match the main repo. I am currently traveling until the 2nd of Feb so I may not be able to test this on a Mac with a HiDPI display set to low-res until I return. From my limited reading, Qt is supposed to handle the scaling transparently, particularly on macOS and iOS devices and Qt 4.7.8 works properly on HiDPI displays.

We currently set the NSHighResolutionCapable flag in the FreeCAD Info.plist as follows:

Code: Select all

<key>NSPrincipalClass</key>
<string>NSApplication</string>
<key>NSHighResolutionCapable</key>
<string>True</string>

I just wonder if the HiRes capable is being overridden somewhere in the code.

From Qt doc:

Applications mostly work with device independent pixels. Notable exceptions are OpenGL and code that works with raster graphics.

My understanding is that we have to take care of the scaling ourselves.

Simple test I have run:
QT_SCALE_FACTOR=2 ./FreeCAD

and changing the code to make Viewport width and height to be twice as big gives good results.

I will try to set the scale factor external to the app to see if that helps as well but again, that might be up to a week away.

I do wonder if setting QT_SCALE_FACTOR=0.5 would "fix" this Viewport issue (icons and everything else should be too small).

Have a nice trip!

Cheers,
Mateusz

Hi,

I tried to build FreeCAD with Qt5 support to see if I have this issue,I'm on Macos 10.10.5 with MacBook Pro Retina.


My cmake without the "-DBUILD_QT5=1" works just fine and
I can build the code successfully.

I've got gt5 from homebrew:

Code: Select all

==> 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 has CMake issues when linked

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
    PKG_CONFIG_PATH: /usr/local/opt/qt5/lib/pkgconfig

Well i am no Mac compile expert but the message is clear:

Code: Select all

Qt5 libraries not found.

Therefore you will need to sort that out.

[nyholku]

Thanks, that was helpful.

The thing is AFAIU this is supposed to build out of the box if pre-requisites are installed (I have qt5) and someone in this thread obviously has built this on Mac so I was thinking there might be a problem in the build process that someone already had figured out.

In FOSS I think re-doing that have already been done is frowned up on.

[triplus]

I doubt we can start using term "out of the box" just yet. After all libraries are involved that weren’t officially released yet. Read the thread and you will see why.

In FOSS I think re-doing that have already been done is frowned up on.

That is correct and @blacey shared a link to a script he uses on Travis in this thread. That i guess is your best bet. He uses some Qt 5 related symlinks in it and that should explain why CMake doesn’t see your Qt 5. Regardless of the fact if it's there or not.

[nyholku]

Thanks, that was actually helpful!

[blacey]

You need to run brew link --force Qt@5.6 to establish the homebrew links. In addition, you will need to create some individual links for make.

Here are the Qt5 install steps we use on Travis (note, some of these commands are used simply blackout Qt4 and install Qt5.6)

There are two relevant branches if you want to build with Qt5. First, I recommend the Qt56 branch in homebrew-freecad. You can use the commands shown in the Travis config to tap the qt56 branch and install the qt56 dependencies.

In addition, there is a Qt5 branch in my FreeCAD fork that includes cmake changes needed to build the FreeCAD app bundle.

Sorry for the slow response but I am traveling.

Good luck.
