If you're not compiling aircrack-ng on Linux, first, you have
 to delete Makefile
 * cygwin  : rename Makefile.cygwin to Makefile
 * MacOSX  : rename Makefile.osx to Makefile
 * windows : use windows package unless you don't need airodump/wzcook
 * On another OS: That's untested, but you have to rename Makefile.other to Makefile

Compilation:
 make

REM: Test files are also compiled.
     You can find a WPA handshake capture and 
      a dictionnary in "test" directory


You can strip debug informations from executables before
installing them with:
 make strip


Installing:
 make install


Uninstall:
 make uninstall
