Question

sudo apt-get install cmake libgmp-dev
sudo cmake .
sudo make

我尝试使用上面的说明从gitub安装csympy。

running install
running build

EnvironmentError: error calling cmake

但是我在cmake期间收到了上述错误。我检查了我安装了gcc-4.8的突触。

cmake -std=c++0x .
cmake -std=c++11 .

我强制cmake使用上面的以下编译器，但是我收到错误消息，指出指定的源目录不存在。编译csympy cmake时我缺少什么？

Answer 1

您缺少C ++编译器。安装g ++

sudo apt-get install g++

之后，您需要清理回购git clean -dfx并再次运行cmake .或python setup.py install

csympy cmake错误：编译器不支持C ++ 11结构
