SonarQube & Qt-based sources

Question

I am novice user of SonarQube. I was tried to analyze some source CPP files through SonarQube (with sonar-cxx plugin), these (source) files are contains of some QT code pieces (inheritance from QSharedData & a few QT macro), but in result I give a strange errors from SonarQube Runner:

Properties file (sonar-project.properties) looks like:

# Required metadata

sonar.projectName=GrainBlitter 0x01
sonar.projectVersion=0.0.xx

sonar.cxx.cppcheck.path=C:/Program Files (x86)/Cppcheck/cppcheck.exe

# Encoding of the source files
sonar.sourceEncoding=UTF-8

# exclude qt created files
sonar.exclusions=**/ui_*.h

I specify QT include dir in [sonar.cxx.include_directories] variable, may be isn't correct? Please give me example of sonar-project.properties file with correct linkage to QT library. Thanks! P.S. QSharedData header are included in my headers

Answer 1

This is very likely due to the extension that qt made to the C++ language (which if I recall goes further than a few macros).

I don't know if sonar can handle this natively (or if there is a plugin) but as a first approach maybe you can run the analysis on the sources after they have been transformed by qt's preprocessor (moc).
