103 . Capisco che CFLAGS (o CXXFLAGS per C ++) sono per il compilatore, mentre CPPFLAGS è utilizzato dal preprocessore. CFLAGS enables the addition of switches for the C compiler, while CXXFLAGS is meant to be used when invoking a C++ compiler. Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor .

By default, CPPFLAGS will be given to the C preprocessor, while CXXFLAGS will be given to the C++ compiler. The GNU Make Manual is a good resource for questions like this (see Implicit Variables ). CPPFLAGS are for the C preprocessor, while CXXFLAGS are for the C++ compiler. See here.

Changelog: Bugfix: Use cxxFlags instead of cppFlags in qbs generator. Docs: conan-io/docs#1354 Close #4730 [*] Refer to the issue that supports this Pull Request. [*] If the issue has missing info, explain the purpose/use case/pain/need that covers this 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.

cflags 表示用于 c 编译器的选项，cxxflags 表示用于 c++ 编译器的选项。这两个变量实际上涵盖了编译和汇编两个步骤。大多数程序和库在编译时默认的优化级别是”2″(使用”-o2″选项)并且带有调试符号来编译，也就是 cflags=”-o2 -g”, cxxflags=$cflags 。 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. CFLAGS vs CPPFLAGS. 103 .

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.

From your Makevars files it seems you are confusing CPPFLAGS with CXXFLAGS / CXX1XFLAGS. CPPFLAGS: C/C++ preprocessor flags. These are applied both to c and c++ preprocessor. Usually this only includes flags that start with -D and -I. CFLAGS / CXXFLAGS / CXX1XFLAGS: Compiler flags CFLAGS vs CPPFLAGS. 103 .
