    Description

      I stumbled on this problem and I am not sure if it's a configuration issue, or some kind of translation that get's applied and causes issues with the shiboken generation process.

      1)  My original shared library compiles just file, and it contains this function declaration in one of the headers file.  This compiles just fine. :

      QVector<double> parseNumericalSequenceToVector(QString& inputLine, 
       QString regexPattern = "(?:^|,)(?=[^\"]|(\")?)\"?((?(1)[^\"]*|[^,\"]*))\"?(?=,|$)");
      

      This library build perfectly using qmake + make

       

      2) this is the problem: when I try to expose this to python, I build the bindings using shiboken.  The "cmake .." command runs just file (see attached CMakeLists.txt), but then when I invoke "make" I get these errors (it seems like that the generated bindings files are escaped again):
