[Lcd4linux-devel] Possible error in configure script

[Mattia Jona-L. <mat...@gm...>]

Hi all,

I'm having some problem in compiling lcd4linux from the svn source.
The compilation fails since the script cannot find the usb.h header file.
Actually the header is correctly installed in linux/usb.h but the configure
script and all source files including this header include it
as #include <usb.h> instead of #include <linux/usb.h>.
The file usb.h is part of the kernel headers and should not reside in
/usr/include
but in /usr/include/linux.

Bye,

Mattia

#include <usb.h> is correct, since it tries to find the "/usr/include/usb.h=
"=20
header installed there by libusb.

The kernel header <linux/usb.h> Shouldn't be used by userspace programs, es=
p.=20
since libusb provides a nice, portable abstraction of the kernel interfaces.

make sure you have libusb and the related devel packages (headers) installe=
d=20
and re-run configure.
