make install fails on *BSD systems

[DarkKirb]

make install fails on FreeBSD 11.1 in scripts/utils.sh, because:

• the shebang requires bash in /bin. FreeBSD puts all non-system software (including bash!) in /usr/local
• the do_install() function uses GNU extensions for cp (cp -t) and ln (ln -r) that are not supported by the BSD versions of these utilities.

BSD version doesn't support cp -t !? Source ? But without -t flag it can break debian build for different debhelper versions which treats double-spaces/tabs differently.

[DarkKirb]

according to cp(1):

https://www.freebsd.org/cgi/man.cgi?query=cp&apropos=0&sektion=1&manpath=FreeBSD+11.2-RELEASE+and+Ports&arch=default&format=html

output when you try to pass -t

I could edit my pull request (#714) to include support for both BSD and debhelper

[colinhb]

Can confirm that OpenBSD's cp and ln do not have the -t and -r flags - which GNU coreutils does. Changes to build on OpenBSD 6.3 are in the diff below - similar to pull request from @DarkKirb. I switched to #!/bin/sh instead of keeping the dependency on bash since I didn't see any bashisms at first glance and think it can be safely removed.

Not sure I understand concern from @khurshid-alam. Believe -t just re-arranges arguments and any space / tab issues could be resolved through quoting or reformatting this script, but I'm not familiar with debhelper.

ln -srf is required for is us devs who compiles without running make (using ./utils install) again and again. Is -r not supported again in bsd? Other than that it looks good. I asked at debian. If they approves I will merge it. Pleae rebase and update the PR.

Still failing on OpenBSD 6.3 sadly.

[khurshid-alam]

@Munchotaur Does it fail even with this pull ?

[Munchotaur]

Yes, still failing due to a directory not being found, I think (username removed from paths):

@Munchotaur My guess is that you do not have bash installed, and scripts/utils.sh: not found is from the interpreter directive in the first line of the script: #!/usr/bin/env bash. You could verify this by running which bash. If bash is correctly installed, it will return the path to bash, which on OpenBSD would be /usr/local/bin/bash, and we'd need to look for another solution.

If you instead get Command not found from which bash, I would suggest using pkg_add bash to install bash. You could uninstall it immediately after building the theme. Alternatively you could edit the script to use /bin/sh as the interpreter or create a link bash from somewhere in your path to /bin/sh (which I would recommend removing immediately after since that is dangerous in general - this version of this script just happens to be ok). Hope that's helpful.

In general I think the dependency on bash is fine. I would recommend adding it to the readme, since utils.sh won't run without it. I can do a PR next week. (On the move this week.)

[Munchotaur]

Progress of a sort! I hardwired the shebang in utils.sh to use /usr/local/bin/bash and the 'not found' error disappeared. Now it falls over at a bunch of 'cp' option differences from the GNU version (-t unknown) -- much like your earlier posts. I don't know offhand if OpenBSD uses broadly the same 'cp' as FreeBSD.
