Cannot deploy project to Heroku about pyswisseph

[astrorigin]

Which OS/system?

@astrorigin this is heroku, a deployment cloud, it uses buildpacks to turn source code into runnable container images.

@sbalsom this is a build error, I'm not sure what build environment heroku offers to python, but to me it looks like it just doesn't have the right one, do you know which version it's trying to build? Or can you give us a library + version that depends on it?

[sbalsom]

Hello, I believe I was able to fix the error. I had two different buildpacks added onto my project, one to build the rails interface and one to run the python script. I rewrote the app as a simple Python/flask app and re-deployed it seemed to fix the issue, using just one python buildpack. I think the build packs were conflicting with one another. I was worried it was some more fundamental issue with Heroku, luckily it is not :) Thank you for your response !

No problem, thanks for the heads-up anyway!

Smells like some Ubuntu flavour. Obviously system was corrupt.

[ShadowJonathan]

I don't think so, she mentioned she used a ruby buildpack mixed in with a python buildpack, the ruby buildpack can provide different critical libraries than python's, and so it's possible that gcc just didn't know where to find the required libraries to build pyswisseph

[astrorigin]

A gcc-based build system with no limits.h can only be corrupt, or a critical package was missing, like libgcc-7-dev or libc6-dev...

Looks likely.

From what i'm seeing right now, ruby's bundler (dependency manager) seems to detect the libraries necessary to build extensions, and install them automatically before attempting to build anything, but correct me if i'm wronfg.
