Hi,
If you are not familar with working with GIT, this is a bit tricky perhaps,
and please do not spend too much time on it.
To proceed make sure you have libusb 1 development headers + libs installed,
and
also automake, autoconf, libtool, and make.
Then
git clone https://github.com/gphoto/libgphoto2.git
cd libgphoto2
autoreconf -i -f
./configure --prefix=/usr
( check if there were errors, and also if USB is enabled)
make
sudo make install
Now "gphoto2 --version" should report libgphoto2 2.5.30.1 as version
and testing could be done.
If this is too difficult, its fine not to test here ... the code will also
be in 2.5.31 once it getst released and gets delivered over regular distribution
updates.
Note that we are only replacing the libgphoto2 library, the "gphoto2" userland
tool will use the replaced library.
Ciao, Marcus
