WiringPi library not found. GPIO support disabled

[Bikey]

I juist tried to build Domoticz form source, according to the Wiki.

However after:
git clone https://github.com/domoticz/domoticz.git dev-domoticz
cd dev-domoticz
cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt

I get the following error:

Code: Select all

-- WiringPi include was found in /usr/local/include...
-- ==== WiringPi library not found. GPIO support disabled.
-- ==== (Please follow http://wiringpi.com/download-and-install/ if you want to use GPIO.)
/usr/bin/c++ -DPCHCOMPILE -O3;-DNDEBUG;-I/home/pi/dev-domoticz/main;-I/usr/include;-I/usr/include;;-DNS_ENABLE_SSL;-DWITH_LIBUSB;-DNS_ENABLE_SSL -x c++-header -o /home/pi/dev-domoticz/stdafx.h.gch/.c++ /home/pi/dev-domoticz/main/stdafx.h

Further building works fine (after resolving from the "undefined reference to symbol 'clock_gettime@@GLIBC_2.4" error as discussed in this topic) but the resulting Domoticz installation does not support the GPIO hardware, as expected.

I have installed WiringPi (according to the link. Directory is placed at /home/pi/wiringPi) and everything works fine with the latest beta 2.2765, so only the building fails.

I'm not a programmer, just following instructions, so what can I do to include the correct libraries? Can you change the CMakeList.txt on GitHub?

This is just a warning, and there is no need to change the cmake script

did you try

cd wiringPi
make static
sudo make install-static

and then build ?

[Bikey]

That helped, I now could build everything and GPIO is working. Thanks, Gizmocuz!

cd wiringPi
make static
sudo make install-static

Actually I ran into the very same thing. Is there a reason why domoticz is linking against the static version of wiringPi? Especially as it doesn´t get installed by default. If there is no good reason, can I suggest to link against the dynamic library? If there is a good reason, it might be a good idea to update the CMakeLists.txt output to indicate that this is the problem. In both cases I can submit a patch...

I'm finding the same installing in Arch Linux. If you could post a patch a here, that'd be great.

:

I need some help, I have this message
make: *** No rule to make target 'static'. Arrêt.

There's a "wiringPi" folder within the "wiringPi" folder that you'll have to "cd" into, so those commands from gizmocuz, including the "cd wiringPi", need to be run from within the main wiringPi folder

It's ok now, I haven't seen the sub folder. Thanks !

This works as expected, might be useful to include this in the wiki page?
