How to download/compile libqt6pas Framework MacOS

[Theo11]

Hi,

I am using Lazarus on MacOS and I want to do cross development for Mac and Windows. So I want to switch to QT6.

For that I need libqt6pas Framework library on MacOS.

• Where can I download the (compiled) library?
• I found the source to build the framework myself (https://github.com/davidbannon/libqt6pas), but now I am missing qmake. Where can I get qmake?

Thanks,
Theo.

qmake is inside qt installation directory, eg /Users/foo/qt/6.5.3/macos/bin, use it with full path and it'll compile bindings w/o problems.

Hi Zeljko,

I don't have this folder.
Where do I get this?

I have downloaded qtbase-everywhere-src-6.8.2 tar file, but it has a different structure you are referring to.

Kind regards,
Theo.

Ah ,I'm using Qt installer so that's why I have everything at right place. Haven't tried build qt from source on mac, so cannot help you.

Hi,

I am a step further, I have downloaded QT, brew install qt, and is now in folder /opt/homebrew/Cellar/qt, it's version 6.8.2_1.
So I have now qmake installed. 
Then I did the following:
- cd /Applications/lazarus/lcl/interfaces/qt6/cbindings
- qmake
- make
- make install
No errors, then I did:
- cd /Library/Frameworks
- ln -s /opt/homebrew/lib/Qt6Pas.framework .

Changed to QT6 widget in Lazaurs and added /Library/Frameworks/ to the library path.
When compiling the code I get a link error:
- Error: ld: framework 'Qt6Pas' not found

What is missing?
Any help?

Thanks,
Theo.

Add -L/Library/Frameworks to the lazarus build options.

I have already added the /Library/Frameworks, but still no success.
These are my compiler options:
/usr/local/bin/fpc
-Tdarwin
-Paarch64
-MObjFPC
-Scghi
-O1
-gw3
-gl
-l
-vewnhibq
-Filib/aarch64-darwin
-Fl/Library/Frameworks

Any hints?
