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. FFLAGS fulfills a similar role. [1]
makedepend solves this problem by parsing the code of C source files to generate a list of dependencies (those header files included directly and indirectly). It is able to understand conditional compilation constructs so as to not generate excessive dependencies. It then appends rules expressing the dependencies to the Makefile.
When Make starts, it uses the makefile specified on the command-line or if not specified, then uses the one found by via specific search rules. Generally, Make defaults to using the file in the working directory named Makefile. GNU Make searches for the first file matching: GNUmakefile, makefile, or Makefile.
Each Makefile.am contains, among other things, useful variable definitions for the compiled software, such as compiler and linker flags, dependencies and their versions, etc. The generated " Makefile.in "s are portable and compliant with the Makefile conventions in the GNU Coding Standards , and may be used by configure scripts to generate a ...

An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
C compilers and programming environments all have a facility that allows the programmer to define where include files can be found. This can be introduced through a command-line flag, which can be parameterized using a makefile, so that a different set of include files can be swapped in for different operating systems, for instance.
The archiver, also known simply as ar, is a Unix utility that maintains groups of files as a single archive file.Today, ar is generally used only to create and update static library files that the link editor or linker uses and for generating .deb packages for the Debian family; it can be used to create archives for any purpose, but has been largely replaced by tar for purposes other than ...
