Hello, I am currently packaging Qt5 for the Buildroot embedded Linux build system (http://buildroot.org).
I am therefore trying to get the 'rasterwindow' example (from qtbase/examples/gui/rasterwindow/) to run with the 'linuxfb' graphics backend on a ARM platform (currently a Cortex-A8 platform emulated by Qemu). I first got a segfault that I could fix, see the patch '[PATCH qtbase] qlinuxfbscreen: fix crash in switchToGraphicsMode()' I just send to this list. But once this first easy issue was fixed, I got another segfault, which this time requires more knowledge of Qt internals, which I don't have. So, basically, I'm starting my application as follows: ./rasterwindow -platform linuxfb and I get the following trace in gdb: Program received signal SIGSEGV, Segmentation fault. QFbBackingStore::QFbBackingStore (this=0x17588, window=0x7efffc34) at fbconvenience/qfbbackingstore.cpp:54 54 (static_cast<QFbWindow *>(window->handle()))->setBackingStore(this); (gdb) bt #0 QFbBackingStore::QFbBackingStore (this=0x17588, window=0x7efffc34) at fbconvenience/qfbbackingstore.cpp:54 #1 0x768ac016 in QLinuxFbIntegration::createPlatformBackingStore (this=<optimized out>, window=0x7efffc34) at qlinuxfbintegration.cpp:87 #2 0x76f33438 in QBackingStore::QBackingStore (this=0x19008, window=0x7efffc34) at painting/qbackingstore.cpp:122 Does anyone has an idea? Should I be doing a formal bug report?
