I am using QT to display PCD file by VTK, I am facing the problem such like; In included file: 'math.h' file not found

I have already checked the 'edit system environment variable', .pro file's INCLUDE file etc. etc. that's fine.

can anyone encounter such issue? please response, thanks indeed.

You should use CMake to configure your project, not QMake. If you insist on using QMake, compile a hello world example using CMake. Then take include paths etc from it and add it to your QMake project.

You can try the absolute path of your math.h file to check that Qt has access to it ( ie: #include "C:\Qt\Tools\mingw530_32\i686-w64-mingw32\include\math.h" ) and if it works, then check Qt INC dirs.
