Hi Jan,
It could be nice if GCC also supports PCH. Well what I did looks like:
if(enabled)
if(msvc)
add command line arguments to the compiler
endif()
endif()
So adding support for any compiler is very straightforward as long as it
behaves a bit the same: under MSVC, you need to:
- add a .cpp and a .h to the project (Precompiled.h and Precompiled.cpp for
instance).
- say the .cpp generation also generates the precompiled header (command line
for the cpp)
- say everything else in the project use this precompiled header (command line
for the project)
- force each cpp in the project to virtually include the Precompiled.h (command
line for the project)
Cheers,
Sukender
