@code{GCC_INCLUDE_DIR} means the same thing for native and cross. It is
|
|
where GCC stores its private include files, and also where GCC
|
|
stores the fixed include files. A cross compiled GCC runs
|
|
@code{fixincludes} on the header files in @file{$(tooldir)/include}.
|
|
(If the cross compilation header files need to be fixed, they must be
|
|
installed before GCC is built. If the cross compilation header files
|
|
are already suitable for GCC, nothing special need be done).
|
|
|
|
@code{GPLUSPLUS_INCLUDE_DIR} means the same thing for native and cross. It
|
|
is where @command{g++} looks first for header files. The C++ library
|
|
installs only target independent header files in that directory.
|
|
|
|
@code{LOCAL_INCLUDE_DIR} is used only by native compilers. GCC
|
|
doesn't install anything there. It is normally
|
|
@file{/usr/local/include}. This is where local additions to a packaged
|
|
system should place header files.
|
|
|
|
@code{CROSS_INCLUDE_DIR} is used only by cross compilers. GCC
|
|
doesn't install anything there.
|
|
|
|
@code{TOOL_INCLUDE_DIR} is used for both native and cross compilers. It
|
|
is the place for other packages to install header files that GCC will
|
|
use. For a cross-compiler, this is the equivalent of
|
|
@file{/usr/include}. When you build a cross-compiler,
|
|
@code{fixincludes} processes any header files in this directory.
