Do you have the pthread library installed ?

[Guruprasad-Rane]

I have libpthread-stubs0-dev installed. Is this the correct package for pthread?

[feragon]

It should be. Can you give me the content of this file ? [build dir]/CMakeFiles/cmTC_8dd12.dir/link.txt
I think CMake isn't pointing to the correct library

[Guruprasad-Rane]

There is no directory named cmTC_8dd12.dir in CMakeFiles. Nothing with cmTC_*****.dir

Do you have the libboost-all-dev installed ?
https://stackoverflow.com/questions/28029195/how-to-let-cmake-use-pthread-instead-of-lpthread

[Guruprasad-Rane]

Yes. libboost-dev as well as libboost-all-dev are installed.

[feragon]

Can you try by removing everything related to threads in CMakeFiles ?
set(Boost_USE_MULTITHREADED ON), set(Boost_USE_MULTITHREADED ON), ${CMAKE_THREAD_LIBS_INIT}, FIND_PACKAGE ( Threads )

In those files : https://github.com/LibreCAD/LibreCAD_3/search?q=Threads&unscoped_q=Threads

[Guruprasad-Rane]

Tried removing or commenting as you said but no luck.
I used cmake --debug-trycompile and all the necessary temp file are there intact.
CMakeFiles.tar.gz
Here is the complete CMakeFiles folder compressed.

[Guruprasad-Rane]

I did a complete fresh git clone and it partly worked this time.

I can reproduce the bug on a fresh install.
You have to change the theme in Menu > Preferences > Qt5 Settings and change the theme.
Cleanlooks works but is ugly.

[Guruprasad-Rane]

Librecad3 started with cleanlooks but looks like this.

Tried to change icons theme on QT5 settings. but not luck.

[Guruprasad-Rane]

qt5ct: using qt5ct plugin
qt5ct: D-Bus global menu: no
Error opening dir: No such file or directory
Output of ./librecad in terminal

[feragon]

I use Brise (KDE Qt theme), and it looks correct.

Concerning the console output, it's a Qt error message, and will not make LibreCAD crash

[Guruprasad-Rane]

Whichever theme I use to select from QT Settings Librecad use to take bb10dark.
So I modified main.cpp
//QApplication::setStyle(QStyleFactory::create(style.getStyle()));
QApplication::setStyle("cleanlooks");
And it worked...
Not sure whether it is problem with LIbrecad or Cinnamon. But other QT based programs are working fine.

@feragon Thank you for the support...

[feragon]

Does it works better if you totally remove QApplication::setStyle ?

[Guruprasad-Rane]

Yes. works better if QApplication::setStyle is removed. Style changes in QT5 settings reflected in Librecad as well.

[feragon]

Ok, then I'm going to remove this.
Thanks for the report !
