what are cflags in makefile?
444917
CFLAGS and CXXFLAGS are either the name of environment variables or of Makefile variables that can be set to specify additional switches to be passed to a compiler in the process of building computer software. ... Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor.

Compact fluorescent light bulbs (CFLs) contain small amounts of mercury. A small percentage of this mercury can be released into the air if the bulbs are broken. Careful clean-up of broken bulbs can minimize the risk of mercury exposure.

The -fPIC option tells the compiler to generate position-independent code (i.e. code that can be loaded at any particular virtual memory address at runtime). ... Others (like x86) don't, but it's still useful to use -fPIC since position-dependent memory references can't be shared by different processes and thus are copied.

GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with #include <file> in: /usr/local/include. libdir/gcc/target/version/include.

Makefile (Generic) MK is a file extension for a makefile. A makefile is used with the UNIX make utility to determine which portions of a program to compile. Essentially, a makefile is a script that guides make in choosing program files should be be compiled and linked together.

GCC does not have this. GCC's PCH mechanism (which is just a dump of the compiler memory image) is related, but is architecturally only able to read the dump back into the exact same executable as the one that produced it (it is not a structured format). Clang is much faster and uses far less memory than GCC.

Theorem: CFLs are not closed under intersection If L1 and L2 are CFLs, then L1 ∩ L2 may not be a CFL. 3. L1 ∩ L2 = {anbnan | n ≥ 0}, which is known not to be a CFL (pumping lemma). Theorem: CFLs are not closed under complement If L1 is a CFL, then L1 may not be a CFL.

The difference is in the location where the preprocessor searches for the included file. For #include "filename" the preprocessor searches in the same directory as the file containing the directive. ... This method is normally used to include standard library header files.
