           Summary: Consider using /usr/bin/env bash in scripts
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: holger+br at freyther.de
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


On FreeBSD bash will not be inside /bin/bash but will be in
/usr/local/bin/bash, by using /usr/bin/env bash one can have a script that
works well with a Linux system and FreeBSD.

When did Build Root start building FreeBSD systems?
I must have missed that memo.

--- Comment #1 from Peter Korsgaard <jacmet@uclibc.org>  ---
Does buildroot otherwise work on freebsd? I would expect some of the host
packages to fail.

I'm not against freebsd support as such, but it needs active testers to ensure
it keeps working as all the main devs use Linux.

In general, the least troublesome option for building embedded Linux systems
with buildroot is running it on a Linux system.

--- Comment #2 from holger+br at freyther.de  ---
I am hacking my way... so here is my incomplete list
I do have symlinks to help me.. with GNU coreutils
  mktemp -> gmktemp
  sed -> gsed
  install -> ginstall

uclibc fails to build a host utility... but on the second gmake just
continues...
  HOSTCC utils/ldconfig.host
In file included from ../utils/ldconfig.c:170:
../utils/readsoname2.c: In function 'readsoname32':
../utils/readsoname2.c:3: warning: implicit declaration of function 'ElfW'
(and more pointers to Elf names)


busybox fails with a include of shadow.h (not present on FreeBSD)

so I do have a basic gcc/uclibc toolchain for mips right now with the below
hacky changes

Does Buildroot build on FreeBSD?

Not sure what to do with those FreeBSD-specific changes. I am not sure we want
to support FreeBSD as a build host, since nobody is actively working on this.
If someone is interested, please send the corresponding patches on the mailing
list. There has been no activity on this FreeBSD topic since may 2011, so I
suspect there simply isn't enough interested people.
