            Bug ID: 13216
           Summary: [Documentation] 2020.02.6 requires GNU find utils
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: waitman at waitman.net
                CC: buildroot at uclibc.org
  Target Milestone: ---

The documentation states that GNU binutils are required, however binutils does
not include "find". If user has a "find" that is not from GNU find utils
package then the Makefile stops with error.

Documentation should specify that GNU find utils are required.

../buildroot-2020.02.6/output/build/host-e2fsprogs-1.45.6

find: unrecognized: -printf


GNU find utils are available at the following URL:

https://www.gnu.org/software/findutils/

(optionally update Makefile so that GNU find utils are not required)

Additionally there is no "2020.06.2" option (the long term support release) in
the version select box, in the bug report.

--- Comment #2 from Peter Korsgaard <jacmet@uclibc.org> ---
Thanks for the report, I have added the 2020.02.6 release now, I must have
missed adding it when I made the release.

The -print0 option is used in quite a lot of places (and may be used by the
build system of various packages as well), so I guess the only sensible
solution is to update our documentation.

Out of interest, what find implementation are you using? Even the busybox
applet supports it.

Sorry, -printf, not -print0. Still, it would be interesting to hear what find
implementation you are using

It's Alpine Linux (edge) 

default 'find' is busybox. help doesn't mention printf. But can install
findutils and it's GNU find with -printf





find 
BusyBox v1.32.0 () multi-call binary.

Usage: find [-HL] [PATH]... [OPTIONS] [ACTIONS]

Search for files and perform actions on them.
First failed action stops processing of current file.
Defaults: PATH is current directory, action is '-print'

        -L,-follow      Follow symlinks
        -H              ...on command line only
        -xdev           Don't descend directories on other filesystems
        -maxdepth N     Descend at most N levels. -maxdepth 0 applies
                        actions to command line arguments only
        -mindepth N     Don't act on first N levels
        -depth          Act on directory *after* traversing it

Actions:
        ( ACTIONS )     Group actions for -o / -a
        ! ACT           Invert ACT's success/failure
        ACT1 [-a] ACT2  If ACT1 fails, stop, else do ACT2
        ACT1 -o ACT2    If ACT1 succeeds, stop, else do ACT2
                        Note: -a has higher priority than -o
        -name PATTERN   Match file name (w/o directory name) to PATTERN
        -iname PATTERN  Case insensitive -name
        -path PATTERN   Match path to PATTERN
        -ipath PATTERN  Case insensitive -path
        -regex PATTERN  Match path to regex PATTERN
        -type X         File type is X (one of: f,d,l,b,c,s,p)
        -executable     File is executable
        -perm MASK      At least one mask bit (+MASK), all bits (-MASK),
                        or exactly MASK bits are set in file's mode
        -mtime DAYS     mtime is greater than (+N), less than (-N),
                        or exactly N days in the past
        -mmin MINS      mtime is greater than (+N), less than (-N),
                        or exactly N minutes in the past
        -newer FILE     mtime is more recent than FILE's
        -inum N         File has inode number N
        -user NAME/ID   File is owned by given user
        -group NAME/ID  File is owned by given group
        -size N[bck]    File size is N (c:bytes,k:kbytes,b:512 bytes(def.))
                        +/-N: file size is bigger/smaller than N
        -links N        Number of links is greater than (+N), less than (-N),
                        or exactly N
        -empty          Match empty file/directory
        -prune          If current file is directory, don't descend into it
If none of the following actions is specified, -print is assumed
        -print          Print file name
        -print0         Print file name, NUL terminated
        -exec CMD ARG ; Run CMD with all instances of {} replaced by
                        file name. Fails if CMD exits with nonzero
        -exec CMD ARG + Run CMD with {} replaced by list of file names
        -delete         Delete current file/directory. Turns on -depth option
        -quit           Exit
