The reason ‘$(CPPFLAGS)’ appears after ‘$(AM_CPPFLAGS)’ or ‘$(mumble_CPPFLAGS)’ in the compile command is that users should always have the last say.It probably makes more sense if you think about it while looking at the ‘CXXFLAGS=-O0’ above, which should supersede any other switch from AM_CXXFLAGS or mumble_CXXFLAGS (and this of course replaces the previous value of CXXFLAGS).

CPPFLAGS. The CPPFLAGS is often mis-understood to set up C++ compiler options. In fact, it is used by C/C++ preprocessors. The reason ‘$(CPPFLAGS)’ appears after ‘$(AM_CPPFLAGS)’ or ‘$(mumble_CPPFLAGS)’ in the compile command is that users should always have the last say.It probably makes more sense if you think about it while looking at the ‘CXXFLAGS=-O0’ above, which should supersede any other switch from AM_CXXFLAGS or mumble_CXXFLAGS (and this of course replaces the previous value of CXXFLAGS). The CFLAGS and CXXFLAGS variables define the optimization flags for the gcc C and C++ compiler respectively. Although we define those generally here, you will only have maximum performance if you optimize these flags for each program separately. The reason for this is because every program is different.

Environment variables CPPFLAGS, CXXFLAGS, CFLAGS, LDFLAGS, LIBS generated by the build helper to use them in the configure, make and install steps. This variables are generated dynamically with the values of the attributes and can also be modified to be used in the following configure,

cflags vs cppflags 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. Prefer setting AM_CPPFLAGS vs. CPPFLAGS, etc.

Situation I am using a handwritten GNUmakefile in which CXXFLAGS, CPPFLAGS and LDFLAGS are appended to by the += assignment, as in: CXXFLAGS += -std=c++11 $(MODENV) $(WARNINGS) $(OPTIMS) CPPFL 2020-03-08 2018-07-17 Currently, quite a few Arduino makefiles use CPPFLAGS (and other custom macros beginning with CPP) as the C++ counterpart for CFLAGS. However, "CPP" in this context means "C preprocessor", not "C plus plus". The right name for C++ flags is CXXFLAGS (think of … cflags vs cppflags 79 Tôi hiểu rằng CFLAGS (hoặc CXXFLAGS cho C++) là dành cho trình biên dịch, trong khi CPPFLAGS được sử dụng bởi bộ tiền xử lý. From your Makevars files it seems you are confusing CPPFLAGS with CXXFLAGS / CXX1XFLAGS. CPPFLAGS: C/C++ preprocessor flags.

CFLAGS and CXXFLAGS The CFLAGS and CXXFLAGS variables define the optimization flags for the gcc C and C++ compiler respectively. Although we define those generally here, you will only have maximum performance if you optimize these flags for each program separately. The reason for this is because every program is different.

The library can be incorporated into larger digital forensics tools and the command line tools can be directly used to find evidence. CFLAGS and CXXFLAGS. 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++.
