In [this
|
|
post](/blog/2013/1/6/registering-an-enum-type-in-glib-s-type-system) I said
|
|
I will get through the GLib Makefiles to add an enum type to GLib in a more
|
|
sophisticated way.
|
|
|
|
In my other project,
|
|
[SWE-GLib](https://github.com/gergelypolonkai/swe-glib) I already used this
|
|
method. The following two rules in `Makefile.am` create `gswe-enumtypes.h`
|
|
and `gswe-enumtypes.c`.
|
|
|
|
{% gist 1e2fdedb136de3ca67f0 Makefile %}
|
|
|
|
`$(GLIB_MKENUMS)` is set in `configure` with
|
|
`AC_PATH_PROG([GLIB_MKENUMS], [glib-mkenums])`.
|
|
|
|
This approach requires the GNU Autotools (you can get rid of it by changing
|
|
`$(GLIB_MKENUMS)` to the path to `glib-mkenums` binary), and two template
|
|
files, one for the header and one for the code. `$(gswe_enum_headers)`
|
|
contains a list of all the header files that have enum types defined
|
|
throughout the project.
|
|
|
|
{% gist 1e2fdedb136de3ca67f0 gswe-enumtypes.h %}
|
|
|
|
{% gist 1e2fdedb136de3ca67f0 gswe-enumtypes.c %}
