CMake fatal error: CMakeFiles/<path>.dir/main.cpp.d: No such file or directory

Question

我正在尝试在 Ubuntu 18.04 上使用 CMake 编译一个简单的 C++ 程序，但是当我运行 make 命令时，我所有的 CMake 项目都失败了。下面是一个最小的工作示例。

目录结构如下所示：

- project directory
|-build
|-main.cpp
|-CMakeLists.txt

main.cpp

int main(void)
{
    return 0;
}

CMakeLists.txt

cmake_minimum_required (VERSION 3.1)
project(Test-Project)

add_executable(a
    main.cpp
)
target_compile_options(a
    PUBLIC -Wall -o -std=c++11
)

建筑

cd build
cmake ../ # this works without any error
make  # this fails

错误

[ 50%] Building CXX object CMakeFiles/a.dir/main.cpp.o
cc1plus: fatal error: CMakeFiles/a.dir/main.cpp.d: No such file or directory
compilation terminated.
CMakeFiles/a.dir/build.make:75: recipe for target 'CMakeFiles/a.dir/main.cpp.o' failed

make[1]: *** [CMakeFiles/a.dir/all] Error 2
Makefile:90: recipe for target 'all' failed
make: *** [all] Error 2

尝试在系统上编译任何基于 CMake 的程序时出现此错误。但是，如果我直接使用 g++ 来编译程序，它会毫无怨言地编译。例如：

g++ ../main.cpp

编译程序，运行程序没有任何错误。

cmake --version: cmake version 3.22.1
g++ --version: g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
g++ -print-prog-name=cc1plus: /usr/lib/gcc/x86_64-linux-gnu/7/cc1plus

使用make VERBOSE=1编译时的终端输出：

尽管关于缺少 .d 文件的错误消息似乎是 CMake 内部的（此类文件用于收集编译器生成的 header 依赖项），其通常的原因是指定一些 output-controlling编译器选项在CMakeLists.txt.

在您的情况下，-o 选项损坏了 CMake 生成的命令行。 CMake 本身使用此选项指定 object 文件，该文件将作为编译结果创建。所以再加一个-o是错误的。
