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.
The configure script, when run, scans the build environment and generates a subordinate config.status script which, in turn, converts other input files and most commonly Makefile.in into output files (Makefile), which are appropriate for that build environment. Finally, the make program uses Makefile to generate executable programs from source ...
After navigating a command-line shell to the directory that contains the source code, the following commands are typically executed: [1] ./configure make make install For the Autotools, the configure script logs status and errors to file config.log , and the command ./configure --help outputs command line help information.
A list of command-line options to be passed to the linker (which libraries the program needs and in what directories they are to be found) Automake also takes care of automatically generating the dependency information, [5] so that when a source file is modified, the next invocation of the make command will know which source files need to be ...
Called meta-build tools, these generate configuration files for other build tools such as those listed above.. CMake – Cross-platform build tool for configuring platform-specific builds; very popoular; integrated with IDEs such as Qt Creator, [1] KDevelop and GNOME Builder [2]
CMake uses a particular generator by default for the host environment. Alternatively, a generator can be selected via the command line option -G. For example, generator Unix Makefiles creates files for make. [4] CMake does not support custom generators without modifying the CMake implementation.
Cygwin also provides the GNU Compiler Collection, GNU make, and other software that provides a nearly complete Unix-like system within Windows; MSYS also provides GNU make and other tools designed to work with the MinGW version of GCC. A consumer can re-generate the configure script which might be necessary if they amend the source code.
If they are not specified in the Makefile, then they will be read from the environment, if present. Tools like autoconf's ./configure script will usually pick them up from the environment and write them into the generated Makefiles. Some package install scripts, like SDL, allow CFLAGS settings to override their normal settings (instead of ...
