Compile with cmake

[camillalc]

Hello,

Nice!! Thanks for sharing the source code.

You provided in #10 one example of how to compile with g++, but how can i create a CMakeLists.txt to compile using cmake?

Rgrds,
Camilla

To use CMake.
Assuming your in the 'main' directory.

Create a build folder

$ mkdir build
$ cd build

Run CMake and Make

$ cmake ..

Find the executable in the 'main' folder (because of the other directories models and img).

$ cd ..
$ tree -L 1

Run

$ ./FaceRecognition

Once FaceRecognition works, you may remove the build directory, since we don't need it any more.

$ sudo rm -rf build

Thank you!!

Hello still can't find solution i followed these steps and stil strugle to run script. After running cmake .. as in example i tried to run make -j4 but nothing happens. Maybe im doing this step in wrong folder (tried running make -j4 everywhere i could)? Or make -j4 needs attributes?

I used fresh SD-image 64bit

Thank you for helping me. Want to run face recognition doors so much.

Look in the parent folder, not the build folder as it holds only temporarily files.
You make gives on errors so it succeeded.
So, from your location ..../build $ cd .. and you find FaceRecognition.

$ cd ..
$ tree -L 1

Once again i did fresh install. After fresh install i used commands "sudo apt update" ; "sudo apt install tightvncserver"

And then followed steps but still cant see the FaceRecognition file. Because make -j4 did nothing :/.

Maybe "sudo apt update" ruins everything?

Using 2gb raspb 4 version

Upade: tried once again on fresh install without "sudo apt update", no progress

For your convenience I've posted a video on Gdrive on how to install and compile the software.
I've used the Bullseye 64-bits OS in the video. The procedure is identical on a Buster 64-bit OS.

Eh... Thank you a lot. I was using Face-Recognition pre-downloaded in SD-image. CMakeLists.txt wasn't there and I just created an empty file :)... named CMakeLists.txt. I thought what was way to go. Thank you a lot once again.
