Qt Creator 100% CPU during code edit

问题

I have Qt Creator project. It uses boost and Point Cloud library. When I edit file that contains includes from these libraries, Qt Creator hangs about 30 seconds after each code channge (line added, variable type changed etc.). TaskManager shows 100% CPU on my two-core procesor.

Please note: it is not during parsing or indexing, i.e. no green progress bar appears.

Qt Creator is 2.8.0.

回答1:

The only way I found is to disable boost and Eigen header parsing. To do it

1. Exclude them from HEADERS section of .pro file

2. Add these lines:

   QMAKE_CXXFLAGS += /I ../3rdparty/eigen /I ../3rdparty/boost /DCOMPILE_TIME

   Now Qt Creator will show you Unknow file warning, but compilation will be OK.
