I Need your help

[PandaK404]

I don't understand rust very well.
When I tried to runnig I encountered the following problems. I don't understand what went wrong? Need your help

error: could not compile `geosteiner-rs-template` (bin "geosteiner-rs-template") due to previous error

It seems like rust can't find the C libraries that contain the actual geosteiner. To build these too use cargo build --features rebuild_c. If that doesn't work use cargo build -vv --features rebuild_c to get more information during the build phase.

Thank you for your reply. I am trying to solve the problem, but there is currently no progress, perhaps because I am not a computer major. Can you tell me how to test all the steps of this library? I will do it again according to your steps (I have already installed Rust)

[Agent59]

I've fixed a bug where the Makefile of the C library changed during the first build. This might have caused the problems you encountered. I've also added a Readme with installation instructions, hope that helps.

I am sorry for the long wait, I'm no cs major too, but rather still a college student and programming is just a hobby, which is why I don't have much time fixing issues.
I apologize.
