Flask App Build Subprocess
I am using a build of an open source software in a flask application to run a subprocess to.
I have a build directory inside of my project and the subprocess I am running is in the software inside of that build folder.
How do I make sure when I deploy to railway it can use that build?
Here is my GitHub Repo for more context! 👇🏼

Update for anyone that might read this later. I set up my Dockerfile to this and it worked!! Thanks so much again @Brody G.O.A.T.
```
Use x86_64 architecture to match Railway’s environment

Hi Brody! Here is that repo not private!
https://github.com/nworbdier/waypoints-x-api
I used a dockerfile to build a version of the gpsbabel (gpsbabel-linux) that is linux/ubuntu (does it have to be that to work on railway)?
When i run the api and hit the endpoints with just the gpsbabel it works perfectly but when i deploy to railway and use that binary it doesn't work!
Then if i use the gpsbabel-linux on Railway it also doesn't work.

When i use gpsbabel i get a response of {"error":"[Errno 8] Exec format error: './bin/gpsbabel'"}
When I use gpsbabel-linux I get a {"error":"Failed to extract waypoints."}
i dont see a dockerfile?
I copied it in from another project so it didn't have to run every time!

right but this project will need a dockerfile to install any system libs that gpsbabel might need
gotcha! I am a inexperienced and had to use ai to help me with this as i had 0 clue how to do it. My api project will need the attached dockerfile?
correct, minus the build stuff
Excuse my dumb questions. So do you mean just this?
please wrap these in triple backticks
you will need more than that, you need to use the python image, install from requirements.txt, and start your app, etc
So basically run my entire project through the dockerfile?
maybe, that sentence does not make technical sense
Where my lack of knowledge shines through.
I think I know what you mean just not articulating it!
fair enough, talk with chat gpt about it, it will be able to help you better than i could since this isnt railway specific
Gotcha!
What version does my gpsbabel build need to be?
I am working from a Macbook so it obviously can't use the cmake .. and make from this machine correct?
the binary you already build for amd64 is fine
Perfect! Thank you!!
