我最近探索了distcc，但不能让它工作。所以我
sudo apt-get remove distcc在那之后，我得到错误

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

export CC=/usr/local/bin/gcc
export CXX=/usr/local/bin/g++但仍然得到相同的错误。
如何解决此错误？我已经尝试重置符号链接并删除导出

我认为你应该取消设置
CC和CXX，或者至少使用系统编译器，像这样（去掉/local）：xcitsw882#
我在安装openCV 4时遇到了类似的错误。2.0与CUDA 10。2在ubuntu 18上。04.我通过（相应更改gcc/g++版本）进行了修正

你需要检查你的gcc和g++的位置，并做一个软链接，因为我使用CentOS
安装gcc所以我需要做以下工作，以避免同样的错误，你

以上所有的建议并没有解决我在Ubuntu 18的问题。04，它为我工作使用：

我在用cuda优化编译opencv时遇到了这个问题。编译器发出这个消息
The CMAKE_C_COMPILER: /usr/bin/gcc-6 is not a full path to an existing compiler tool.see the output of cmake这个消息实际上很清楚，因为它只是告诉它没有找到gcc-6的指示位置，在这个例子中是/usr/bin/gcc-6。为了验证这一点，我导航到/usr/bin/文件夹，并运行命令ls gcc*来查看所有可用的gcc GNU C编译器。The image below shows what I got.可以看出，它们不是gcc-6，而是gcc-9。因此，我只需要指出相关路径-D CMAKE_C_COMPILER=/usr/bin/gcc-9和每一个思考工作找到。
