Using QtSerialPort results in "APPCRASH"

[M4chin3]

Hi,

i'm trying to use the QtSerialPort Libary (http://qt-project.org/wiki/QtSerialPort). The install process worked fine (with Perl installed).
The problem is, as soon as i start my test program (debug or release mode) it crashes with this error:

My setup is:

Qt 5.0.2 32 bit
QtSerialPort Stable (f301591)


Any ideas?

Your exe is not able to find the correct dll for QSerialPort. It is able to link properly but absence of dll causes it to crash. Check the dll with right name (QSerialPort0.dll / QSerialPort.dll, check the wiki...) is available in the path of executable.
