| |
| Contains the UnixCCompiler class, a subclass of CCompiler that handles |
| the "typical" Unix-style command-line C compiler: |
| * macros defined with -Dname[=value] |
| * macros undefined with -Uname |
| * include search directories specified with -Idir |
| * libraries specified with -lllib |
| * library search directories specified with -Ldir |
| * compile handled by 'cc' (or similar) executable with -c option: |
| compiles .c to .o |
| * link static library handled by 'ar' command (possibly with 'ranlib') |
| * link shared library handled by 'cc -shared' |
