How to Install from Code

[Happylinzy]

Describe the bug
I tried to follow the guide saying sudo make install but it shows that
""make: *** No targets specified and no makefile found. Stop.""

To Reproduce
I run the following instructions. Did I miss something?

git clone git@github.com:ZigRazor/CXXGraph.git
cd CXXGraph
git clone https://github.com/google/googletest.git
cd googletest # Main directory of the cloned repository.
mkdir -p build # Create a directory to hold the build output.
cd build
cmake .. # Generate native build scripts for GoogleTest.
make # Compile
sudo make install # Install in /usr/local/ by default
cd ../..
mkdir -p build
cd build
cmake ..
make
sudo make install

Afther I type make in CXXGraph/build, there is no output. Then when I run sudo make install. It says no targets.

Expected behavior
Find a test_exe in this build directory to run unit test

I tried the following instructions on running benchmark and it seems to work.

1. Follow benchmark instructions to download googletest in benchmark folder.
2. Build the benchmark. Though when I tried the final step "sudo cmake --build "build" --config Release --target install", it says no target is found.
3. Compile the benchmark following instruction.

This time the CPM detects the benchmark and google test.

Next when I tried make, I find error as

/home/yinix/CXXGraph/build/_deps/zlib-src/test/example.c:8:10: fatal error: zlib.h: No such file or directory
    8 | #include "zlib.h"
      |          ^~~~~~~~
compilation terminated.
make[2]: *** [_deps/zlib-build/CMakeFiles/example.dir/build.make:76: _deps/zlib-build/CMakeFiles/example.dir/test/example.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:1703: _deps/zlib-build/CMakeFiles/example.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

This is due to a missing package of ruby and zlib1g-dev in ubuntu. Then I install the library using

sudo apt-get install ruby zlib1g-dev

After this, I tried make again and it succeeds.

Then when one tries to build from source, it is better to directly build the benchmark.

The benchmark_exe shows in CXXGraph/build/benchmark/

[Happylinzy]

However, the test_exe is still missing.

@Happylinzy

However, the test_exe is still missing.

Use cmake -DTEST=ON ..

@kamari-a We should document this somewhere.

[AryanGitHub]

can you please share the step-by-step procedure on how to build this project and install it from the source?
I tried

git clone git@github.com:ZigRazor/CXXGraph.git
cd CXXGraph/
mkdir build
cd build/
cmake ..
cmake --build .
sudo make install

CLI returned:
make: *** No rule to make target 'install'. Stop.
Also usr/include/ does not not have the header files.

i am doing a fix for this, but then i have to move $(project_dir)/include folder to $(project_dir)/include/$(project_name).
It's kind inspired by https://github.com/google/googletest/tree/main/googletest/include. They dont have hpp files just after the include folder.
