Fails to build on ubuntu 20.04.4

[xloem]

Build log: https://dweb.link/ipfs/bafybeifnhfeoo6lj4pnk7xudqf7m3k5gxzgvhghc7n2vzajwdkqtctrfmy/make.log

gcc version: 7.5.0

[ahelwer]

I think this is because of -wall -wextra -werror

[darrigu]

I think this is because of -wall -wextra -werror

NO! It is for error reporting. When you don't know, don't say anything plz

[darrigu]

What is the github of the project ?

[xloem]

I have edited away this comment I made while upset and confused, which I am very sorry for. I guess frexsdev must have misposted the github project question here by accident, and I responded very poorly. If it's unclear, this github right here is the project in question. Be well, frexsdev and ahelwer. Thank you for looking at my issue.

[dundargoc]

Is this still a problem? If so we need more information. The provided link also does not work.

[xloem]

I am no longer using either ubuntu or this project at this time, but here is more conventional ipfs.io link to the build log: https://ipfs.io/ipfs/bafybeifnhfeoo6lj4pnk7xudqf7m3k5gxzgvhghc7n2vzajwdkqtctrfmy/make.log . It's just an ipfs file; it's still on ipfs.

Here's the content. Do IPFS links from other people work for you?

[dundargoc]

Those are just warnings. Werror has been removed. Just ignore.

[xloem]

Thanks. These warnings of course are intended to catch severe buffer overflows. I infer you have reviewed the code and situation and verified it is okay.

[dundargoc]

Lol no. But I can't recreate the warning. If you can, feel free to open a new issue.

[xloem]

Thanks. I'm not set up to test this anymore. We'll see. But thank you.
