fatal error: keyfinder/keyfinder.h: No such file or directory

[robertin0]

Hi guys,
I receive an error on make saying:
fatal error: keyfinder/keyfinder.h: No such file or directory

i installed libkeyfinder in /usr/lib/libkeyfinder but also in /usr/lib/keyfinder and /usr/lib/lkeyfinder
I'm on Debian GNU/Linux bookworm/sid
what am I doing wrong??
thanks rob

Could you expand on what commands you're running to install the tool?

[drbarzyk]

╰─➤ make
c++ keyfinder_cli.cpp -std=c++11 -Wall -lkeyfinder -lavcodec -lavformat -lavutil -lswresample -lfftw3 -o keyfinder-cli
keyfinder_cli.cpp:5:10: fatal error: 'keyfinder/keyfinder.h' file not found

@drbarzyk you have libkeyfinder installed? What OS are you on? where is the shared library installed?

[jordyf15]

make install
g++ keyfinder_cli.cpp -std=c++11 -Wall -lkeyfinder -lavcodec -lavformat -lavutil -lswresample -lfftw3 -o keyfinder-cli
keyfinder_cli.cpp:5:10: fatal error: keyfinder/keyfinder.h: No such file or directory

Hello, i also encounter the same problem.
I used WSL and i installed the libkeyfinder in /home/username by following the steps in the libkeyfinder repo which resulted in /home/username/include/keyfinder and /home/username/lib.
Is there any other information i could help provide?

I've also had a little trouble building both projects but that's just because I don't do that often and am not familiar with the respective paths.

On Ubuntu via WSL2, the following steps worked for me:

In my cloned libkeyfinder repo directory (from https://github.com/mixxxdj/libkeyfinder/), I did this:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local -S . -B build
cmake --build build --parallel 2
sudo cmake --install build

(cmake --build build --parallel 2 because the Windows task manager shows 2 cores for the CPU on this system.)

In my cloned keyfinder-cli repo directory, I did this:

sudo apt-get install libavutil-dev libavcodec-dev libavformat-dev
make
sudo make install

Then I ended up with a shiny new keyfinder-cli executable in /usr/local/bin/.

The ffmpeg package was already installed on my system.

Thanks for this project, @evanpurkhiser!

Next I'll be looking for a command-line tool to properly detect the BPM...

Hello, I had the same problem. I was able to resolve it finally with these steps. I hope it helps others. Greetings!

1. Install libkeyfinder in the path of git repository keyfinder-cli:
   cmake -DCMAKE_INSTALL_PREFIX=/path_to_keyfinder-cli_repository/ -S . -B build

2. Add this texto to the file /path_to_keyfinder-cli_repository/Makefile, -I argument and -L argument:
   keyfinder-cli: keyfinder_cli.cpp key_notations.h $(CXX) $< -std=c++11 -Wall -lkeyfinder -lavcodec -lavformat -lavutil -lswresample -lfftw3 -I"./include" -L"./lib" -lkeyfinder -o $@

3. Launch make command

Info extracted from .github/workflows/main.yml

sudo apt-get install --yes \
            libswresample-dev libavformat-dev libavutil-dev libavcodec-dev \
            cmake **catch2** libfftw3-dev

If fail catch2, compile from -> git clone https://github.com/catchorg/Catch2.git

Launch inside of keyfinder-cli repository cloned in you system

git clone https://github.com/mixxxdj/libkeyfinder keyfinder
cd keyfinder
cmake -S . -B build
cmake --build build
sudo cmake --install build

Return to keyfinder-cli repository directory

make; make install;

Note: It is not necessary to fix the Makefile.

Note 2: if fail import of libkeyfinder.so, use:

export LD_LIBRARY_PATH=/path_to_keyfinder-cli_repository/lib

Thanks, when I try to run make I get:
make: *** No rule to make target 'g++', needed by 'keyfinder-cli'. Stop.
