genXrnPattern binary location/installation?

It’s looking in the same directory as the main binary. It will also check the GENXRDPATTERN_EXECUTABLE environment variable too.

It should check the whole PATH though:

github.com/OpenChemistry/avogadrolibs

avogadro/qtplugins/plotxrd/plotxrd.cpp

4b5eea466


      
            return true;
          }
          
          bool PlotXrd::executeGenXrdPattern(const QStringList& args,
                                             const QByteArray& input, QByteArray& output,
                                             QString& err)
          {
            QString program;
            // If the GENXRDPATTERN_EXECUTABLE environment variable is set, then
            // use that
            QByteArray xrdExec = qgetenv("GENXRDPATTERN_EXECUTABLE");
            if (!xrdExec.isEmpty()) {
              program = xrdExec;
            } else {
          // Otherwise, search in the current directory, and then ../bin
          #ifdef _WIN32
              QString executable = "genXrdPattern.exe";
          #else
              QString executable = "genXrdPattern";
          #endif
              QString path = QCoreApplication::applicationDirPath();

On the roadmap is to clean this up a bit so other programs can supply an XRD pattern (e.g., a Python plugin using pymatgen)
