使用Ninja构建eos项目时遇make无目标无Makefile报错求助

Hey there, let's break down what's causing your issue and how to fix it quickly:

The Root Cause #

You used cmake -G "Ninja" to generate build files, which creates Ninja build scripts instead of traditional Makefiles. When you ran make, it couldn't find a Makefile to execute—hence the error. Also, this project uses CMake for configuration, so there's no ./configure script (that's why you got the "No such file or directory" message).

Solution 1: Use Ninja (since you already generated Ninja build files) #

In your build directory, replace the make && make install command with:

ninja && ninja install

This will use the Ninja build system you configured earlier to compile and install the project.

Solution 2: Switch back to Makefiles #

If you prefer using make instead, clean your current build directory first, then re-run CMake without the Ninja generator:

cd ../build
rm -rf *
cmake ../eos -DCMAKE_INSTALL_PREFIX=../install/
make && make install

This will generate standard Makefiles that the make command can recognize.

Quick Note #

You don't need to run ./configure for this project—CMake handles all the configuration steps when you run the cmake command.
