Avast 为运行时出现 CMake 问题

Question

当 avast 防病毒运行ning 运行ning Windows 10 上运行ning CMake 时，我遇到了问题。

我写了一个小基础CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)

# set the project name
project(RayTracing)

# add the executable
add_executable(rat_tracing main.cpp)

当我运行 cmake -G "MSYS Makefiles" CMakeLists.txt 激活 Avast 时，我得到::

-- The C compiler identification is GNU 10.3.0
-- The CXX compiler identification is GNU 10.3.0
-- Detecting C compiler ABI info
CMake Error at C:/Program Files/CMake/share/cmake-3.23/Modules/CMakeDetermineCompilerABI.cmake:49 (try_compile):

  The C compiler

    "C:/Program Files/msys64/mingw64/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:





  CMake will not be able to correctly generate this project.

  CMakeLists.txt:4 (project)


-- Configuring incomplete, errors occurred!

但是当我禁用 Avast 时，一切正常，我得到：

-- The C compiler identification is GNU 10.3.0
-- The CXX compiler identification is GNU 10.3.0
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done

我做了一些研究，但似乎没有人遇到过同样的问题。最相似的情况是 Avast 认为 Cmake 是病毒的情况。

谢谢。

Answer 1

在处理另一个小型 c++ 项目时，我找到了解决此问题的方法。

创建一个小的“你好词！”程序。

main.cpp

#include <iostream>

int main() {
    std::cout << "Hello word ! " << std::endl;

    return 0;
}

还有一个小 CMakeLists.txt。

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

# set the project name
project(Tutorial)

# add the executable
add_executable(Tutorial main.cpp)

使用cmake或cmake-gui配置和构建项目。

此时会出现Avast的警告。它会说 CMakeLists.txt 正在尝试修改受保护的目录，在我的例子中是“C:/Users/pc/Documents/”，并会询问您是否允许它或不是。授权它，它将适用于任何其他项目。
