如何让 Conda 找到 cc1plus？

Question

当我在 Ubuntu 上编译软件包时，出现此错误

x86_64-conda_cos6-linux-gnu-cc: error trying to exec 'cc1plus': execvp: No such file or directory

我所有必需的库都位于名为CUSENV的 conda 环境中

诊断

conda环境激活后：

1. find /usr -name "cc1plus"

/usr/lib/gcc/x86_64-linux-gnu/7/cc1plus

2. 我还可以看到这个可执行文件： /home/ms/anaconda3/envs/CUSENV/libexec/gcc/x86_64-unknown-linux-gnu/4.8.5/cc1plus

3. echo $PATH

/home/ms/anaconda3/envs/CUSENV/bin:/home/ms/anaconda3/bin:/home/ms/anaconda3/bin:/home/ms/anaconda3/bin:/home/ms/anaconda3/bin:/home/ms/anaconda3/condabin:/home/ms/anaconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

如何正确连接此cc1plus？

你应该首先安装 g++

conda install -c conda-forge gxx_linux-64

然后

cd /home/ms/anaconda3/envs/CUSENV/bin
ln -s /home/ms/anaconda3/envs/CUSENV/bin/x86_64-conda_cos6-linux-gnu-g++ g++
