Я пытаюсь установить этот плагин: https://github.com/CatxFish/obs-v4l2sink
Я выполнил все шаги (установил QT, получил исходный код obs-studio и затем попытался собрать плагин):
sudo apt install qtbase5-dev
git clone --recursive https://github.com/obsproject/obs-studio.git
git clone https://github.com/CatxFish/obs-v4l2sink.git
cd obs-v4l2sink
mkdir build && cd build
cmake -DLIBOBS_INCLUDE_DIR="../../obs-studio/libobs" -DCMAKE_INSTALL_PREFIX=/usr ..
Но потом ...
-- Configuring done
CMake Error in CMakeLists.txt:
No known features for CXX compiler
""
version .
-- Build files have been written to: /home/********/obs-v4l2sink/build
Я впервые компилирую с использованием cmake
(вместо make
), и я не очень разбираюсь в компиляции , Был ли какой-то шаг, который я пропустил между установкой cmake
и попыткой скомпилировать плагин?
Из того, что я нашел в Интернете, вот что я сделал:
build-essential
уже установлен; c++
, cc
и все также установлен; - попытался добавить
-DCMAKE_CXX_COMPILER=/usr/bin/cc
в командную строку cmake
(сделал то же самое с c ++);
И, конечно, я сделал update && upgrade
Вот что находится в файле CMakeError.log:
