[builds] Necessary changes to make 'dlg' compile.
* autogen.sh (copy_submodule_files): New script to copy all the necessary source and include files from `submodules/dlg` to `src/dlg`. * src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables the build of 'dlg' if the `FT_LOGGING` macro is defined. * src/dlg/rules.mk: New sub-Makefile. * builds/freetype.mk (DLG_DIR): New variable to include the header files of the 'dlg' library. (INCLUDES): Add `DLG_DIR`. (FT_CFLAGS): Add `-std=c99' flag. Include `src/dlg/rules.mk` file to build 'dlg' library. (OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`. * builds/toplevel.mk: For builds directly from the git repository we need to copy files from `submodule/dlg` to `src/dlg`. * include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING): New macro to enable or disable the logging facility in FreeType.

[builds] Necessary changes to make 'dlg' compile.
|
||||
|
||||
* autogen.sh (copy_submodule_files): New script to copy all the
|
||||
necessary source and include files from `submodules/dlg` to
|
||||
`src/dlg`.
|
||||
|
||||
* src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables
|
||||
the build of 'dlg' if the `FT_LOGGING` macro is defined.
|
||||
|
||||
* src/dlg/rules.mk: New sub-Makefile.
|
||||
|
||||
* builds/freetype.mk (DLG_DIR): New variable to include the
|
||||
header files of the 'dlg' library.
|
||||
(INCLUDES): Add `DLG_DIR`.
|
||||
(FT_CFLAGS): Add `-std=c99' flag.
|
||||
Include `src/dlg/rules.mk` file to build 'dlg' library.
|
||||
(OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`.
|
||||
|
||||
* builds/toplevel.mk: For builds directly from the git repository
|
||||
we need to copy files from `submodule/dlg` to `src/dlg`.
|
||||
|
||||
* include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING):
|
||||
New macro to enable or disable the logging facility in FreeType.
|
||||
|
||||
2020-11-27 Priyesh Kumar <priyeshkkumar@gmail.com>
|
||||
|
||||
* .gitmodules: Add 'dlg' library's git repository as submodule.
