Also has some utility methods used by several compiler classes. The basic idea behind a compiler abstraction class is that each instance can be used for all the compile/link steps in building a single project. Thus, attributes common to all of those compile and link steps -- include directories, macros to define, libraries to link against, etc. -- are attributes of the compiler instance. To allow for variability in how individual files are treated, most of those attributes may be varied on a per-compilation or per-link basis.

The exact set of executables that may be specified here depends on the compiler class (via the 'executables' class attribute), but most will have: compiler the C/C++ compiler linker_so linker used to create shared objects and libraries linker_exe linker used to create binary executables archiver static library creator On platforms with a command-line (Unix, DOS/Windows), each of these is a string that will be split into executable name and (optional) list of arguments. (Splitting the string is done similarly to how Unix shells operate: words are delimited by spaces, but quotes and backslashes can override this.

Note that 'libname' should *not* be the name of a file containing a library, but the name of the library itself: the actual filename will be inferred by the linker, the compiler, or the compiler class (depending on the platform). The linker will be instructed to link against libraries in the order they were supplied to 'add_library()' and/or 'set_libraries()'. It is perfectly valid to duplicate library names; the linker will be instructed to link against libraries as many times as they are mentioned.

'sources' must be a list of filenames, most likely C/C++ files, but in reality anything that can be handled by a particular compiler and compiler class (eg. MSVCCompiler can handle resource files in 'sources'). Return a list of object filenames, one per source filename in 'sources'. Depending on the implementation, not all source files will necessarily be compiled, but all corresponding object filenames will be returned. If 'output_dir' is given, object files will be put under it, while retaining their original path component. That is, "foo/bar.c" normally compiles to "foo/bar.o" (for a Unix implementation); if 'output_dir' is "build", then it would compile to "build/foo/bar.o". 'macros', if given, must be a list of macro definitions. A macro definition is either a (name, value) 2-tuple or a (name,) 1-tuple. The former defines a macro; if the value is None, the macro is defined without an explicit value. The 1-tuple case undefines a macro. Later definitions/redefinitions/ undefinitions take precedence. 'include_dirs', if given, must be a list of strings, the directories to add to the default include file search path for this compilation only. 'debug' is a boolean; if true, the compiler will be instructed to output debug symbols in (or alongside) the object file(s). 'extra_preargs' and 'extra_postargs' are implementation- dependent. On platforms that have the notion of a command-line (e.g. Unix, DOS/Windows), they are most likely lists of strings: extra command-line arguments to prepend/append to the compiler command line. On other platforms, consult the implementation class documentation. In any event, they are intended as an escape hatch for those occasions when the abstract compiler framework doesn't cut the mustard. 'depends', if given, is a list of filenames that all targets depend on. If a source file is older than any file in depends, then the source file will be recompiled. This supports dependency tracking, but only at a coarse granularity.

'output_libname' should be a library name, not a filename; the filename will be inferred from the library name. 'output_dir' is the directory where the library file will be put. 'debug' is a boolean; if true, debugging information will be included in the library (note that on most platforms, it is the compile step where this matters: the 'debug' flag is included here just for consistency). 'target_lang' is the target language for which the given objects are being compiled. This allows specific linkage time treatment of certain languages. Raises LibError on failure.

The "bunch of stuff" consists of the list of object files supplied as 'objects'. 'output_filename' should be a filename. If 'output_dir' is supplied, 'output_filename' is relative to it (i.e. 'output_filename' can provide directory components if needed). 'libraries' is a list of libraries to link against. These are library names, not filenames, since they're translated into filenames in a platform-specific way (eg. "foo" becomes "libfoo.a" on Unix and "foo.lib" on DOS/Windows). However, they can include a directory component, which means the linker will look in that specific directory rather than searching all the normal locations. 'library_dirs', if supplied, should be a list of directories to search for libraries that were specified as bare library names (ie. no directory component). These are on top of the system default and those supplied to 'add_library_dir()' and/or 'set_library_dirs()'. 'runtime_library_dirs' is a list of directories that will be embedded into the shared library and used to search for other shared libraries that *it* depends on at run-time. (This may only be relevant on Unix.) 'export_symbols' is a list of symbols that the shared library will export. (This appears to be relevant only on Windows.) 'debug' is as for 'compile()' and 'create_static_lib()', with the slight distinction that it actually matters on most platforms (as opposed to 'create_static_lib()', which includes a 'debug' flag mostly for form's sake). 'extra_preargs' and 'extra_postargs' are as for 'compile()' (except of course that they supply command-line arguments for the particular linker being used). 'target_lang' is the target language for which the given objects are being compiled. This allows specific linkage time treatment of certain languages. Raises LinkError on failure.
