android gcc cflags

CFLAGS and CPPFLAGS were used as part of the implicit rule for.c compilation CXXFLAGS and CPPFLAGS were used as part of the implicit rule donyayevironeh.cf compilation Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in. The CPPFLAGS macro is the one to use to specify #include directories.. Both CPPFLAGS and CFLAGS work in your case because the make(1) rule combines both preprocessing and compiling in one command (so both macros are used in the command).. You don't need to specify. as an include-directory if you use the form #include " ".You also don't need to specify the standard compiler include directory. Option Summary. Here is a summary of all the options, grouped by type. Explanations are in the following sections. Overall Options. See Options Controlling the Kind of Output.

Is the android gcc cflags user supposed to set these variables at all?

Do any automatic tools automakeautoconfetc set them? The linux system that i am supposed to use doesn't define any of these variables - is this typical? I am pretty sure there are no bugs here; the Makefile works very well.

Sorry for so many questions; you will obviously not answer them all but i hope the answers will help android gcc cflags understand the general idea behind these settings. They implement a set of conventions. Macros is an old name for them, android gcc cflags, still used by some. GNU make doc calls them variables. The only reason that the names matter is the default make rules, visible via make -pwhich use some of them. The Android NDK, for one huge example. Compiling C programs n.

And just to make what Mizux said as a minimal example:, android gcc cflags. Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:.

Same thing, android gcc cflags. Jack in when I met make they called them macros. Thanks guys. Jack, no, no no. I'm not trying to school you, just to explain from whence came my particular view.

Clang binaries are automatically included in standalone toolchains. Note: GCC binaries are also included, because Clang relies on the same assembler, linker, headers, libraries included in the GCC distribution. This operation also installs two wrapper scripts, named clang and clang++, under /bin.
