The second attempt failed again, getting a lot of:

[...] undefined reference to 'bla bla bla' [...]

I attach the new linux_4.6.2-3_i386.build:

http://gnuinos.org/linux_4.6.2-3_i386.build

No worries :)

I made a huge mistake!! The following lines were not superfluous:

AC_CHECK_HEADER([libudev.h],
     [AC_MSG_ERROR([Missing /usr/include/libudev.h])])

Now, before a third attempt, i had made sure that all of the missing
libraries exist in libudev-compat-dev, and maybe in a few hour we will
have a systemd-free kernel. This is the list:


struct udev *udev_new(void);

struct udev_enumerate *udev_enumerate_new(struct udev *udev);

int udev_enumerate_add_match_subsystem(struct udev_enumerate
*udev_enumerate, const char *subsystem);

int udev_enumerate_add_nomatch_sysattr(struct udev_enumerate
*udev_enumerate, const char *sysattr, const char *value);

int udev_enumerate_scan_devices(struct udev_enumerate *udev_enumerate);

struct udev_list_entry *udev_enumerate_get_list_entry(struct
udev_enumerate *udev_enumerate);

struct udev_device *udev_device_unref(struct udev_device *udev_device);

struct udev_list_entry *udev_list_entry_get_next(struct udev_list_entry
*list_entry);

const char *udev_list_entry_get_name(struct udev_list_entry *list_entry);

struct udev_device *udev_device_new_from_syspath(struct udev *udev,
const char *syspath);

const char *udev_device_get_sysattr_value(struct udev_device
*udev_device, const char *sysattr);

const char *udev_device_get_sysname(struct udev_device *udev_device);

struct udev_enumerate *udev_enumerate_unref(struct udev_enumerate
*udev_enumerate);

struct udev *udev_unref(struct udev *udev);

struct udev_device *udev_device_new_from_subsystem_sysname(struct udev
*udev, const char *subsystem, const char *sysname);

const char *udev_device_get_sysattr_value(struct udev_device
*udev_device, const char *sysattr);

const char *udev_device_get_driver(struct udev_device *udev_device);

const char *udev_device_get_syspath(struct udev_device *udev_device);

const char *udev_device_get_sysname(struct udev_device *udev_device);


Cheers,

Aitor.
