Did you run qmake?

Try
https://github.com/LibreCAD/LibreCAD/wiki/Build-from-source
or
http://wiki.librecad.org/index.php/Build_from_source

Nevermind... I see you did run qmake.
I wish I could help...

hi Dima,

you should run

qmake -r librecad.pro

or simply:

qmake -r

because the top folder contains only one .pro file from the official repository.

Unable to collect, after some time the process freezes. Screenshot attached.

I only see warnings, which won't stop the build.

The stable ppa will probably be updated within 24 hours.

There no error shown.

What do you mean with freezing

It is possible to get kinds of freezing if you runs out of memory, or overheat the cpu.

If you added the -j make argument, that could possibly freeze it.
Try without -j.

Scott Howard updated the wiki articles for Qt 5,

fixed the compiler warnings: https://github.com/LibreCAD/LibreCAD/commit/8602cde3282ca984e98a59d0b5b0180c64929f3d

Thanks, they weren't showing with default clang settings.
