G15 driver

[5h4rk1337]

Hi there,
how can I make lcdproc work with my Logitech G15? I would love to see if my G15 would work with lcdproc. My goal is it, to have a system monitor on the LCD. The G15Daemon gives me just a clock.

OS: Pop 22.04 jammy
Kernel: x86_64 Linux 6.5.6-76060506-generic

When I run ./configure --enable-drivers=all it says:
checking for g15daemon_client.h... no configure: WARNING: libg15daemon_client.h not found, the g15 driver will lack g15daemon support checking for libg15render.h... no configure: WARNING: The g15driver needs libg15render.h

Found the Source Code of libg15render somewhere in the internet and uploaded it to GitHub.

Thank you for your support <3

@5h4rk1337 I went through the same issue at first and ended up with the following:

1. git clone G15 tools from here: https://github.com/mike-petersen/g15tools/
2. build and install libg15
3. build and install libg15render (required a small patch for me)
4. build and install LCDproc

I am on Arch Linux and package for the G15 render library simply misses the required g15font struct and a bunch of other functions used by LCDproc:

• https://aur.archlinux.org/packages/libg15render

...which is based on:

• https://gitlab.com/menelkir/libg15render/

Building the libg15 from g15tools was straight forward for me:

./bootstrap
./configure
make
sudo make install

Building the libg15render from g15tools required a bit more effort. First patch the configure.in:

diff --git a/libg15render/configure.in b/libg15render/configure.in
index 0f55d3b..8a989e6 100644

                ttf_support="yes"
        else
                ttf_support="no"

...then you can build and install:

./bootstrap
./configure --enable-ttf --prefix=/usr/local
make
sudo make install

Please note that the --prefix here is required even if using the default, since otherwise the fonts directory will be set to NONE.

Now we can build LCDproc:

sh autogen.sh
LDFLAGS="-L/usr/local/lib" ./configure --enable-drivers=g15 --prefix=/usr/local
make
sudo make install

To make it all come together at runtime, we need to start the server like this:

LD_LIBRARY_PATH="/usr/local/lib:/usr/local/lib/lcdproc" /usr/local/sbin/LCDd -c /usr/local/etc/LCDd.conf -f

The main reasons are:

• libg15render is installed in /usr/local/lib
• LCDproc libraries are installed in /usr/local/lib/lcdproc

Also make sure to configure the server:
