Hi,
today I found libwacom 0.1 on sf.net page, it looks great and I
already made an Arch Linux package so people can start using it in
their projects. I also wanted to check if I will be able to find some
details on my device using this lib (actually I made this as part of
learning Python ctypes and calling functions from C libs, but that's
another story :)) - anyway, I was unable to get device by path, is
this already known thing? I did simple:
#include "libwacom/libwacom.h"
int main() {
WacomError* error = libwacom_error_new();
WacomDeviceDatabase* database = libwacom_database_new();
WacomDevice* device = libwacom_new_from_path(database,
"/dev/input/wacom", 0, error);
return 0;
}
with device correctly created, connected and working (link made by
udev, it is pointing to event7 which is stylus of my 0xD1 Bamboo
Pen&Touch). I built it using "gcc -I /usr/include/libwacom-1.0 -lwacom
test.c -o test" (btw, I believe the libwacom-1.0 could be removed from
path, i.e. it would be easier to find if it was in
/usr/include/libwacom/libwacom.h for example), anyway, it builds
without issue, but when I run the simple thing that should return
device or NULL on error, at least according to documentation, the app
hangs forever with following output:
(process:6319): GLib-GObject-CRITICAL **: gtype.c:2715: You forgot to
call g_type_init()
(process:6319): GLib-CRITICAL **: g_once_init_leave: assertion
`initialization_value != 0' failed
(process:6319): GLib-GObject-CRITICAL **: g_object_new: assertion
`G_TYPE_IS_OBJECT (object_type)' failed
if this is new thing, I'd be happy in helping to track it down :)
Cheers,
Andrzej.
