build successful but files are not copied and protobuf is not compiled

[yellowflash07]

After running make, i get libmediapipe_c.so under bazel-bin/mediapipe_api. its not copied to SDK/Plugins and protobuf compiles were nowhere to be found.

the build was successful but had many warnings below is the result. everything is in order, openCV, android sdk are set correctly. i am able to build official examples too.

one thing i found was that the files it was trying to access were locked so i ran "sudo make" which gave

Either the path attribute of android_sdk_repository or the ANDROID_HOME environment variable must be set. even thought it was already set.

then i set it manually in workspace, then build completed succesfully after checking some caches in 5 seconds which didn't do anything.

result of make:-

what am i doing wrong? I'm sorry I am new to linux.

[homuler]

Please run make install after make. (cf. https://github.com/homuler/MediapipeUnityPlugin#build)
make compiles protobuf files and build libmediapipe_c.so, Google.Protobuf.dll, and a zip file which contains mediapipe models but not copy them to the target directories (exceptionally, protoc outputs the compiled files under Assets/Mediapipe/SDK/Scripts/Protobuf).

one thing i found was that the files it was trying to access were locked so i ran "sudo make" which gave
Either the path attribute of android_sdk_repository or the ANDROID_HOME environment variable must be set. even thought it was already set.

If you run make with sudo, root user's environment variables will be used instead of yours.

[homuler]

Project structure changed recently, so if you have placed some files under Assets/Mediapipe/SDK/Plugins, you may need to remove those files first.

[yellowflash07]

oh i am sorry i read the build info as

gpu for make and cpu for make install.

its working now

thank you .
