build fails, seems to be run in wrong directory?

[Garfonso]

For me install / rebuild fails with this error message:

gyp: binding_old.gyp not found (cwd: /home/achim/development/pokemonGoController/node_modules/.pnpm/@u4+opencv4nodejs@7.1.2/node_modules/@u4/opencv4nodejs/cjs) while trying to load binding_old.gyp

Which makes sense, because in node_modules/@u4/opencv4nodejs/cjs there is no binding.gyp or anything else, that the script searches for. The stuff is in node_modules/@u4/opencv4nodejs, i.e. one dir up.

I have no real clue, why the build fails this way. It's on an Arch based system, maybe that is a clue here?

I had to copy the following files there to make it build:

• binding.gyp
• binding_old.gyp
• bin/instal.js (whole bin folder)

Then had to edit cjs/bin/install.js to not load from ../cjs/install/... but from ../install.

Then I got this error:
gyp: Duplicate target name "opencv4nodejs#target" in directory "." used both in "binding.gyp" and "binding_old.gyp".
So I tried to edit the file binding_old.gyp and change the target (adding _old)...

And now I get this error and don't know what to do (never really understood makefile magic):
make: *** Keine Regel vorhanden, um das Ziel „Release/obj.target/opencv4nodejs/cc/opencv4nodejs.o“, benötigt von „Release/obj.target/opencv4nodejs.node“, zu erstellen. Schluss.

Btw. I'm trying to run: build-opencv --nobuild rebuild from my package root. In the package.json I have the following defines, since opencv is installed in the system and it should use the system opencv:

  "opencv4nodejs": {
    "disableAutoBuild": 1,
    "opencvIncludeDir": "/usr/include/opencv4",
    "opencvLibDir": "/usr/lib",
    "opencvBinDir": "/usr/bin"
  }

Any hints would really be helpful. Thanks. :-)

//Edit: After all this failed tries, I found a build/config.gpy created in my base dir. Is this expected? Is this package not meant to be a dependency of another project? Still lost here...

Also.. thanks for keeping this project alive (I hope you still do). It's really fun to play with opencv in node.js and I know all the build stuff really sucks.... (at least for me).

[Garfonso]

Ok, I found a way.
I use the parameter --ignore-scripts to successfully install the package, then the files are in node_modules/@u4/opencv4js.
I can open a command line there and run in that directory node-gyp configure and node-gyp rebuild and it will build the binding. I also set the environment variables, not 100% sure I need to do that. Building the binding itself takes some time already.

Thanks for the work. If this issue hits just me, feel free to close here.
