c++ - 将编译器更改为Clang

Question

好吧，我正试图安装一个WASM组件，我一直收到这个错误，我需要做什么？

cmake -DBINARYEN_BIN=~/binaryen/bin -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib -DCMAKE_CXX_COMPILER=/path/to/c++ -DCMAKE_C_COMPILER=/path/to/cc -DCMAKE_BUILD_TYPE=Debug ..
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

    /path/to/cc

  is not a full path to an existing compiler tool.

  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.

解决这一问题的一步是按照错误日志的明确建议行事。
您需要告诉它您的gcc（或clang）编译器在哪里，您可以通过键入which gcc或根据标题的建议键入which clang来找到它。
然后对g++编译器执行同样的操作。
如果你没有这两个，你需要先安装它们。
然后将cmake命令中的/path/to/cc和path/to/c++更改为实际路径。
