C/C++ preprocessor flags … configure usually does a good job at setting appropriate values for these variables, but there are cases where you may want to override them. PG_CPPFLAGS. will be prepended to CPPFLAGS. PG_CFLAGS.

Herkömmlicherweise ist es die Heimat von Präprozessorflags (-D, -U) und sowohl C als auch C++ verwenden sie.

CFLAGS vs CPPFLAGS. 103 . Eu entendo que CFLAGS (ou CXXFLAGS para C ++) são para o compilador, enquanto CPPFLAGS é usado pelo pré-processador.

make中的默认规则（在我的机器上，无论如何）传递CPPFLAGS给几乎所有东西，CFLAGS仅在编译和链接C CXXFLAGS时传递，并且仅在编译和链接C ++时传递。 If AM_CPPFLAGS is used, then any Bob> per-target CPPFLAGS option completely overrides it. Thanks for pointing this out. I'm checking this in.

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

The CPPFLAGS is often mis-understood to set up C++ compiler options. In fact, it is used by C/C++ preprocessors. 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. Similarly, FFLAGS enables the addition of switches for a Fortran compiler.

Aber ich verstehe den Unterschied immer noch nicht. Entiendo que CFLAGS (o CXXFLAGS para C ++) son para el compilador, mientras que CPPFLAGS es utilizado por el preprocesador.

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.

Reason is Brian +Cameron's recent changes that move libbla_la_CXXFLAGS to +libbla_la_CPPFLAGS, which causes the build to fail on my system. The FLAGS +are just not being set, so I don't have any -I Prefer setting AM_CPPFLAGS vs.

The Sleuth Kit® (TSK) is a library and collection of command line digital forensics tools that allow you to investigate volume and file system data. 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.

Bygg biblioteken med dessa inställningar (detta kan ta upp mot 30-40 min):. Under den längsta tiden trodde jag att CPPFLAGS i Makefiles var för att skicka Så småningom fick jag veta att CXXFLAGS är rätt Makefile-variabel för att  Se även Skillnad mellan CPPFLAGS och CXXFLAGS i GNU Make och CFLAGS vs CPPFLAGS.

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. Nhưng tôi vẫn không hiểu sự khác biệt. When you’re building a sizable project you’re going to be making use of a lot of tools that may have local dependences.
