I am trying to compile a simple C program with CMake on Ubuntu 18.04, but all of my CMake projects fails when I run the make command. Below is a minimum working example.

The directory structure looks like this:

- 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
)

Building

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

Error

[ 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.

make[1]: *** [CMakeFiles/a.dir/all] Error 2

I get this error when try to compile any CMake based program on the system. However, if I just used g directly to compile the program, it compiles without any complaints. For example:

g   ../main.cpp

compiles the program, and runs the program without any errors.

• 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
• uname -a: Linux <computer name> 5.4.0-91-generic #102~18.04.1-Ubuntu SMP <date time> x86_64 x86_64 x86_64 GNU/Linux

EDIT

Terminal output when compiled with make VERBOSE=1:

CodePudding user response：

Despite the error message about absent .d file seems to be internal to CMake (such files are used for collect header dependencies generated by the compiler), its usual reason is specifying some output-controlling compiler options in the CMakeLists.txt.

In your case it is -o option which damages the command line generated by CMake. CMake by itself uses this option for specify object file which will be created as a result of the compilation. So adding another -o is wrong.
