No QPA while building Qt5

Mefrio

Hi guys,

I am trying to build latest qt5 from git and, running configure, I get this error:

@Could not determine the target architecture!
Turn on verbose messaging (-v) to see the final report.
No QPA platform plugin enabled!
If you really want to build without a QPA platform plugin you must pass
-no-qpa-platform-guard to configure. Doing this will
produce a Qt that can not run GUI applications.
The dependencies needed for xcb to build are listed in
src/plugins/platforms/xcb/README
*** qtbase/configure exited with non-zero status.

My configure command is like the one on the "doc":http://qt-project.org/wiki/Building_Qt_5_from_Git, plus the -no-c++11 flag
@./configure -developer-build -opensource -nomake examples -nomake tests -no-c++11@

also it seems that I have all the requested libs

Have you followed the "building doc":http://qt-project.org/wiki/Building_Qt_5_from_Git for Qt 5?

Nevertheless, I think full build log would help more with this problem. In my case there was errors in some other place than this.

I have followed the tutorial you linked.

Here is the full build log running configure:
@mario@mario-pc:~/qt5$ ./configure -developer-build -opensource -nomake examples -nomake tests -no-c++11

/home/mario/qt5/qtbase/configure -developer-build -opensource -nomake examples -nomake tests -no-c++11

"qmake is broken"
"Turn on verbose messaging (-v) to see the final report."

Do full cleanup and try configure again with verbose mode

Building with verbose option after a cleanup give me this error:

@'cd qtsensors && make install failed: 512

I solved the problem using the qt5 beta1 wizard installer.
