missing mkfs

[unlucio]

I'm installing this on macOS Sonoma 14.5 (23F79) via the provided script
I stumbled on the bug described here, and happily passed the block by applying the provided patch.
make and sudo make install ran fine after patching the source, but when I tried to test my install as suggested I got:

➜  tempfuse /opt/gnu/sbin/mkfs.ext4 /tmp/test-fs.ext4
zsh: no such file or directory: /opt/gnu/sbin/mkfs.ext4

Looking for mkfs.ext4 on my drive is nowhere to be found, tho fsck.* are present:

can someone suggest what i did wrong, or perhaps point me in the right direction?

I had a similar problem and solved it, and while it's not exactly the same as your issue, I hope this will point you in the right direction. (Differences: I did not install using the install script, but rather used homebrew to get the prerequisites, and that I'm on Monterey.)

mkfs.ext4 comes from e2fsprogs, so check your compilation and installation of that software. (Your find command should have found it in the e2fsprogs source directory from the install script, but maybe you cleaned up those files before running it.) That's probably where the issue is.

[In my case, the issue was that brew install e2fsprogs installs the file into /opt/homebrew/opt/e2fsprogs/sbin/, which are not in the default $PATH. Homebrew warns you about it when you install, but that was a while ago. As part of debugging I forced it to reinstall, and so had a chance to see the warning. Between your find command and the fact that you used the install script, I don't think this is your issue, but I'm mentioning it in case it helps someone else.]

Another thought is that you can use mke2fs -t ext4 instead of mkfs.ext4. According to a Linux man page that I found, they're supposed to be the same thing. So if you can find mke2fs, that should be close enough.
