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 <[email protected]> --- 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.

--- Comment #4 from Waitman Gobble <[email protected]> --- 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

#apk add findutils

# find 
find (GNU findutils) 4.7.0

Usage: find [-H] [-L] [-P] [-Olevel] [-D debugopts] [path...] [expression]

default path is the current directory; default expression is -print expression may consist of: operators, options, tests, and actions:
operators (decreasing precedence; -and is implicit where no others are given):
( EXPR ) ! EXPR -not EXPR EXPR1 -a EXPR2 EXPR1 -and EXPR2
EXPR1 -o EXPR2 EXPR1 -or EXPR2 EXPR1 , EXPR2
positional options (always true): -daystart -follow -regextype

normal options (always true, specified before other expressions):
-depth --help -maxdepth LEVELS -mindepth LEVELS -mount -noleaf --version -xdev -ignore_readdir_race -noignore_readdir_race
tests (N can be +N or -N or N): -amin N -anewer FILE -atime N -cmin N
-cnewer FILE -ctime N -empty -false -fstype TYPE -gid N -group NAME -ilname PATTERN -iname PATTERN -inum N -iwholename PATTERN -iregex
PATTERN
-links N -lname PATTERN -mmin N -mtime N -name PATTERN -newer FILE -nouser -nogroup -path PATTERN -perm [-/]MODE -regex PATTERN -readable -writable -executable
-wholename PATTERN -size N[bcwkMG] -true -type [bcdpflsD] -uid N
-used N -user NAME -xtype [bcdpfls] -context CONTEXT

actions: -delete -print0 -printf FORMAT -fprintf FILE FORMAT -print

      -fprint0 FILE -fprint FILE -ls -fls FILE -prune -quit
      -exec COMMAND ; -exec COMMAND {} + -ok COMMAND ;
      -execdir COMMAND ; -execdir COMMAND {} + -okdir COMMAND ;

Valid arguments for -D:
exec, opt, rates, search, stat, time, tree, all, help Use '-D help' for a description of the options, or see find(1)

Please see also the documentation at http://www.gnu.org/software/findutils/.
You can report (and track progress on fixing) bugs in the "find" program via the GNU findutils bug-reporting page at
