Currently this .mk snippet results in unexpected behavior from
check-package:
|VAR_1 = VALUE1
|ifeq (condition)
|VAR_1 := $(VAR_1), VALUE2
|endif
Fix commit "163f160a8e utils/{check-package, checkpackagelib}:
consistently use raw strings for re.compile" that ended up doing this:
- CONCATENATING = re.compile("^([A-Z0-9_]+)\s*(\+|:|)=\s*\$\(\\1\)")
+ CONCATENATING = re.compile(r"^([A-Z0-9_]+)\s*(\+|:|)=\s*\$\(\\1\)")
But raw strings do not expect escaping when referencing \1 and the
pattern ends up searching for a raw '\\1' instead of an occurrence of
the first pattern inside parenthesis.
|$ python3

|Type "help", "copyright", "credits" or "license" for more information.
|>>> import re
|>>> p1 = re.compile('(foo)bar\\1')
|>>> p2 = re.compile(r'(foo)bar\\1')
|>>> p3 = re.compile(r'(foo)bar\1')
|>>> s1 = 'foobarfoo'
|>>> s2 = 'foobar\\1'
|>>> print(p1.search(s1))
|<re.Match object; span=(0, 9), match='foobarfoo'>
|>>> print(p2.search(s1))
|None
|>>> print(p3.search(s1))
|<re.Match object; span=(0, 9), match='foobarfoo'>
|>>> print(p1.search(s2))
|None
|>>> print(p2.search(s2))
|<re.Match object; span=(0, 8), match='foobar\\1'>
|>>> print(p3.search(s2))
|None
|>>>
So use '\1' instead of '\\1' in the raw string.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
