compile error

Hi Compile error on Ubuntu 19

error: unrecognized command line option ‘-mfpu=vfp’ g++: error: unrecognized command line option ‘-mfloat-abi=hard’

How do I compile this on Ubuntu PC I have the pulse-eight cec adaptor

The current build command is for Raspbian OS on a Raspberry Pi. I don't have your OS and hardware to test on, so this is just a guess. Try using

g++ -std=c++1z -fPIC -g -Wall -lcec -ldl cec-simplest.cpp -o cec-simplest

This is what i got when I typed that command

`g++ -std=c++1z -fPIC -g -Wall -lcec -ldl cec-simplest.cpp -o cec-simplest ````

Ii have Intel Core i5 CPU 650 what other info do you need ?

[DrGeoff]

git pull to get a fix for that std::min type error problem. Then try compiling with g++ -std=c++1z -fPIC -g -Wall cec-simplest.cpp -lcec -ldl -o cec-simplest

[Electrik-rich546456]

How do I git pull ??

[Electrik-rich546456]

Ok so I downloaded the master zip again and ran above command...

g++ -std=c++1z -fPIC -g -Wall cec-simplest.cpp -lcec -ldl -o cec-simplest
$ cec-simplest
cec-simplest: command not found
$ ./cec-simplest

And Now just sits there with a flashing cursor. What is it suppose to do ? cec-client still works and displays the stream of info...

[Electrik-rich546456]

Ive just looked at the code and I think I see. Is it suppose to read out keys pressed from the Tv remote ?

my connections might make it easier to understand my project. < TV> ------->------CEC DEV>---->----<PC

Can i use this to run in the background and listen for function keys F8-F12 press and do things like change tv source or turn tv on and off the code would also need to detect TV change audio source and if source switched away from PC 1 don't turn TV off,

2. if source is on PC then monitor for screen saver activity on the dbus and if screen turns off sent tv to sleep. or off via cec.

I have all these functions working using cec-client in bash scripts but i wanted to integrate it into a single python script using the py library but didn't work, then I found this project and thought there is no harm in asking. Would you be able to help me?

[DrGeoff]

This repository is about introducing the libcec C/C++ interface in the simplest way possible. It simply prints out TV remote key presses.

I think your project is possible with libcec but I don't have the time to write your code.

Best wishes, Geoff
