Installing LIBCEC on Wheezy (tested on a Samsung TV)

[OoM_JaN]

Step by step installation of the LIBCEC module on a Wheezy Rapberry.



Start in the home directory

Code: Select all

cd /home

Install the necessary tools for compiling:

Code: Select all

sudo apt-get install build-essential autoconf liblockdev1-dev libudev-dev git libtool pkg-config

Clone the git repository:

Code: Select all

sudo git clone git://github.com/Pulse-Eight/libcec.git

Compile:

Code: Select all

cd libcec

Code: Select all

sudo ./bootstrap

Code: Select all

sudo ./configure --with-rpi-include-path=/opt/vc/include --with-rpi-lib-path=/opt/vc/lib --enable-rpi

Code: Select all

sudo make

Code: Select all

sudo make install

Link the libraries so that cec-client can find them:

Code: Select all

sudo ldconfig

Check that cec-client have found the device by running:

Code: Select all

cec-client -l

Found devices: 1

device: 1
com port: RPI
vendor id: 2708
product id: 1001
firmware version: 1
type: Raspberry Pi

To send commands to for instance a connected TV:

Turn off TV:
echo “standby 0” | cec-client -s

I just want to add that you need all your libraries set in /opt/vc

Check if there is an include and lib folder in /opt/vc. If there isn't one download the raspberry firmware master repos: https://github.com/raspberrypi/firmware

Copy the opt/vc folder from this repos to your own /opt/vc folder and the configure will work flawless. If you don't do this then you will get the error: configure: error: Raspberry Pi API not found or incompatible with libCEC

Hello.

Will this library work with Samsung LCD monitor with HDMI input. Or CEC is just for TVs?

[danielblarg]

Thanks for this, I've got it working well with my Panasonic TV.
It wasn't working until I switched to a different HDMI cable.

Now I'm using python-cec (https://github.com/trainman419/python-cec) to make a script to control the Pi with the TV remote.

Beautiful - works almost perfectly out of the box, thank you very much!

Just a couple of points:

For the git clone command, if you leave off the "sudo" from the beginning, it creates the directory under your own user account, thus obviating the need for the "sudo" command through the rest of the steps up to

Code: Select all

sudo make install

This is also the preferred method because it means you don't end up with files belonging to root (which you can't edit or delete) in the user home directory.


Secondly, there is a development in automake (specifically, libtoolize) that is going to break the process as described here because the macros that

Code: Select all

./bootstrap

uses to create the files that

Code: Select all

./configure

works on need to be in their own directory at the top of the source tree.

What that means (in non-geek speak) is that after

Code: Select all

sudo git clone git://github.com/Pulse-Eight/libcec.git

cd libcec

you need to create the m4 directory;

Code: Select all

mkdir m4

and then edit configure.ac;

Code: Select all

 nano 

(or your editor of choice)

Code: Select all

 configure.ac

After the line

Code: Select all

CFLAGS="$cflags_reset"

add

Code: Select all

AC_CONFIG_MACRO_DIR([m4])

and in Makefile.am (nano again, or your equivalent to edit it), add

Code: Select all

ACLOCAL_AMFLAGS = -I m4

then continue with

Code: Select all

 ./bootstrap 

If you're seeing the errors

Code: Select all

 libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

this is how you fix that!

Probably will not work because of no CEC on monitor. Consult the specs of the monitor. If the monitor does not have a remote control (of the TV type) with 'transport' buttons (play, stop, rewind etc) then the chances are slim.

Hi,

Sorry for this post in this old thread.

But they have changed the compile method of LibCEC.

So you can't run the shell script by the command ./bootstrap.

Do anybody know which Release will work.

Hi

I have tested it with the Release 2.2.0, but i have to use this configure command

Code: Select all

sudo ./configure --with-rpi-include-path="/opt/vc/include" --with-rpi-lib-path="/opt/vc/lib/" --enable-rpi

Can anybody tell me, what I have to do, to compile it with cmake?

[magro]

Did somebody have success with libCEC version 3 ?

[nlrb]

Yes, I've the listed the steps in this post.

[magro]

TKS nlrb. It works fine.

[spiru]

Can someone please tell me why I am getting ./bootstrap: command not found after I try sudo ./bootstrap. I'm a newbie in linux guys.
I would appreciate help cause this is killing me

[DougieLawson]

Because dot slash (./) in front of a file name means look in the current working directory and your "bootstrap" script isn't in there.

[spiru]

Thanks for the reply. So Do I have to get the libcec bootstrap file from somewhere? or bootstrap is an OS command file, is it installed in a default directory?

[dragos]

Hi, has anybody solved this ./bootstrap problem? I also get command not found! How do I solve it? Thought this is a good tutorial but full of wrong info!

[acki]

Have a look at the documentation for raspberry included!

To compile libCEC on a new Raspbian installation, follow these instructions:

Code: Select all

sudo apt-get update
sudo apt-get install cmake libudev-dev libxrandr-dev python-dev swig
cd
git clone https://github.com/Pulse-Eight/platform.git
mkdir platform/build
cd platform/build
cmake ..
make
sudo make install
cd
git clone https://github.com/Pulse-Eight/libcec.git
mkdir libcec/build
cd libcec/build
cmake -DRPI_INCLUDE_DIR=/opt/vc/include -DRPI_LIB_DIR=/opt/vc/lib ..
make -j4
sudo make install
sudo ldconfig

I tried this für libCEC version 4.0.0 on a quite fresh OSMC-installation and it worked fine!
