Embedded ARM Seg Faults Adding Widget to Layout

[flob]

Hi All,

I am working with Qt Embedded 4.5.3, cross compiled under Ubuntu for an ARM9 target platform.

I am receiving SIGSEVG on QApplication.exec(), and have traced it back to a call from the main window (which happens to be a QWidget) on ui->layout->addWidget(widget). The layout on the designer-generated widget is a QVBoxLayout, and "widget" is a custom QWidget.

The closest I'm getting to any reason to this behavior is a HUGE (screens and screens full) spam of "QLine::unitVector: New line does not have unit length," followed by an "ASSERT: "t >= 0" in file painting/qbezier_p.h." Unfortunately I don't know where to go from there.

As a side note, the same code does run as intended on Ubuntu and OS X, so I'm a bit at a loss...

Thanks in advance.

If anyone has the same issue -

The answer was, mismatched libraries between what was used by the toolchain to create the target filesystem, versus what was used to compile the Qt application. Whereas that really doesn't make a screaming amount of sense given that all the Qt-and-dependent libraries were also copied into the target's library directory, recompiling the application using the same toolchain made it work just dandy.
