It was made to be very configurable, and should be enough to describe most builds. The parameters of the class are: - ConfigureClass: set this to be the class (i.e., build step) that will be called to configure GDB. It needs to accept the same arguments as the ConfigureGDB class above. The default is to use ConfigureGDB. - CompileClass: set this to be the class (i.e., build step) that will be called to compile GDB. It needs to accept the same arguments as the CompileGDB class above. The default is to use CompileGDB. - TestClass: set this to be the class (i.e., build step) that will be called to test GDB. It needs to accept the same arguments as the TestGDB class above. The default is to use TestGDB. - extra_conf_flags: extra flags to be passed to "configure". Should be a list (i.e., []). The default is None. - enable_targets_all: set this to True to pass '--enable-targets=all' to configure. The default is True. - extra_make_flags: extra flags to be passed to "make", when compiling. Should be a list (i.e., []). The default is None. - extra_make_check_flags: extra flags to be passed to "make check", when testing. Should be a list (i.e., []). The default is None. - test_env: extra environment variables to be passed to "make check", when testing. Should be a dictionary (i.e., {}). The default is None. - test_parallel: set to True if the test shall be parallelized. Default is False. Beware that parallelizing tests may cause some failures due to limited system resources. - make_command: set the command that will be called when running 'make'. This is needed because BSD systems need to run 'gmake' instead of make. Default is 'make'. - use_system_debuginfo: set to False if GDB should be compiled with the "--with-separate-debug-dir" option set to "/usr/lib/debug".
