Checks

• [x] I have read the troubleshooting section and still think this is a bug.

Describe the bug you encountered:

I am not a programmer, I just wanted to compile fd for AIX. The compilation ended up with errors see attachment. Am I making a mistake somewhere? Is there any way to fix it?

That looks to me like the nix crate doesn't support AIX.

And yes, it isn't listed as a supported target on their readme

[tavianator]

It's probably possible to make nix an optional dependency. But is there an easy way to test builds on AIX? Otherwise we're kinda programming blind

[arozehnal]

I understand that there is a problem with the availability of AIX for testing. But if it is about compilation and verification of functionality, I offer my help.

I managed to build fd on AIX, but I'm not really confident about my workaround codes to contribute it to public. But here are some changes to make it work on AIX:

1. switched to using libc instead of nix due to lack of support. Also get rid of crtlc because it depends on nix too
2. disable LTO because there is an issue with proc-macros on AIX
3. Jemalloc does not work on AIX either

@arozehnal if you need the binary or .diff file, I will provide it

[arozehnal]

OK, binary will be fine :-)

[huynp1999]

Seems like github does not allow to upload file in comment. Anyway, I put it on https://play.min.io:9443, account minioadmin:minioadmin. Go to bucket name "testbucket", and you will find the fd binary in there =))

Also you need to install dependencies in IBM_OPEN_XL_CPP_UTILITIES_17.1.3.0_AIX.tar.Z from https://www.ibm.com/support/pages/ibm-open-xl-cc-utilities-aix-1713 Unzip and installp all .rte in it

[arozehnal]

Thanks a lot, it works on the first try. :-)

I'm still missing bat I can't compíle on AIX either. I thought it would get better after update Rust SDK for AIX. But the status is the same.
