[Scons-users] Qt5 build on OSX

[Dirk Bächle]

Hi Daniele,


thanks a lot for reporting your problems to this mailing list and 
including some references to work that has been done earlier.

When I followed the provided URLs, I saw that you got an answer from 
paveljanik for how to restore the *.pc files under Qt 5.7.x as well. Can 
you try the described steps and report back if they worked?


Regarding the "OSX framework" support for the Qt4/Qt5 tools, there has 
been a pull request by Philip Kraus, if I remember correctly. But it 
didn't make it into the main branch because his solution broke part of 
the original functionality under Linux. If you have access to an OSX 
machine and would be ready to work on this some more just raise your 
hand. I'd be more than glad to work together with you on this issue.


Best regards,


Dirk
