Description

Disclaimer: I am fairly new to Golang and IPFS world. I am trying to run kubo with the help of gomobile in an Android app. The process of creating a node is failing with long error saying

constructing the node: could not build arguments for function "github.com/ipfs/kubo/core/node".PeerWith.func1 (/Users/apple/go/pkg/mod/github.com/ipfs/kubo@v0.27.0/core/node/peering.go:30):

: opening IPFS_PATH: exec: "getent": executable file not found in $PATH

What i understood from the error is that the ipfs core package is trying to access GETENT program from the underlying linux arch which is restricted on non-rooted devices. But i am struggling to solve this.

I have created a minimal reproducible example in this repo https://github.com/athulantonynp/ipfs-android-golang with the build instructions.

Also here is my go env output.

Any leads to solve this issue appreciated.

PS: I have seen some other repos like https://github.com/ipfs-shipyard/gomobile-ipfs and it is working fine even though their approach to create the nodes are similar except the Golang & Kubo versions are bit old compared to what i have used. I guess it shouldn't be a problem.

Android builds aren't officially supported, although if there any fixes / changes to support that are simple enough we're happy to take them (this particular issue doesn't seem particularly actionable). Looking at what gomobile-ipfs is doing or leveraging the underlying libraries from boxo seems like the best bet.

You may have better luck asking on the forums http://discuss.ipfs.tech/ or chat channels https://docs.ipfs.tech/community/#chat.

I've encountered this as well, how do I solve this problem?

The same issue happened here on Android.
