Options defined by variables
You can generally specify the compiler that is used and the options that should be passed to it by declaring variables after the ./configure command. For example, to define the C compiler and the options to give it, you could run
[name@server ~]$ ./configure CC=icc CFLAGS="-O3 -xHost"
The most commonly used variables include
| Option | Description |
|---|---|
| CFLAGS | Options to pass to the C compiler |
| CPPFLAGS | Options to pass to the preprocessor and to C, C++, Objective C, and Objective C++ compilers |
| CXXFLAGS | Options to pass to the C++ compiler |
| DEFS | Allows the definition of a preprocessor macro |
| FCFLAGS | Options to pass to the Fortran compiler |
| FFLAGS | Options to pass to the Fortran 77 compiler |
| LDFLAGS | Options to pass to the linker |
| LIBS | Libraries to link |
A more exhaustive list of variables and typical options is available in the autoconf documentation.
