linux - 更新后的 Ubuntu cmake 错误

Question

将 cmake 更新到 3.12.1 版后出现错误

CMake Error at /usr/local/share/cmake-3.12/Modules/CMakeDetermineSystem.cmake:174 (file):
  file attempted to write a file:
  /home/wow/TrinityCore/CMakeFiles/CMakeOutput.log into a source directory.
Call Stack (most recent call first):
  CMakeLists.txt:19 (project)


CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

任何帮助或想法？

谢谢!

Answer 1

正如评论中已经指出的那样，消息

file attempted to write a file ... into a source directory

是 CMAKE_DISABLE_SOURCE_CHANGES 的结果在项目的 CMakeLists.txt 中设置的变量.此设置激活检查，CMake 项目不会在源目录下创建任何文件。 (此变量设置的更精确描述见 that answer)。
通常设置 CMAKE_DISABLE_SOURCE_CHANGES变量伴随设置 CMAKE_DISABLE_IN_SOURCE_BUILD变量，字面意思:
该项目不应该在源代码中构建。
解决方案是构建项目 外源 ，在与源目录不同的构建目录中。
例如。那样:

cd <project-dir>
mkdir build
cd build
cmake ..
