Je comprends que CFLAGS (ou CXXFLAGS pour C ++) sont pour le compilateur, alors que CPPFLAGS est utilisé par le préprocesseur. Mais je ne comprends toujours pas la différence. J'ai besoin de spécifier un chemin d'inclusion pour un fichier d'en-tête qui est inclus avec #include - parce que #include est une directive de préprocesseur, le préprocesseur (CPPFLAGS) est-il la seule chose qui

CXXFLAGS¶. This is a CMake Environment Variable.Its initial value is taken from the calling process environment. Default compilation flags to be used when compiling CXX (C++) files. Will only be used by CMake on the first configuration to determine CXX default compilation flags, after which the value for CXXFLAGS is stored in the cache as CMAKE_CXX_FLAGS.

Я понимаю, что CFLAGS (или CXXFLAGS для C++) предназначены для компилятора, в то время как CPPFLAGS используется препроцессором. Но я все There are packages for gcc-4.8 and 4.9 , and also llvm/clang 3.0 .

The most important flags are -mcpu and -march. -mcpu=pentium3 means the code will be optimized to run on Pentium3, but will also run on i386. -march=pentium3 means the code will only run on a

I understand that CFLAGS(or CXXFLAGS for C++) are for the compiler, whereas CPPFLAGS is used by the preprocessor. But I still don't understand the difference.

CFLAGS and CXXFLAGS are used to set up C and C++ compilers respectively. On most Linux system, the C compiler is usually gcc, while the C++ compilers is usually g++. CPPFLAGS. The CPPFLAGS is often mis-understood to set up C++ compiler options.
