[U-Boot] [PATCH 0/3] improve build for UNIX like non GNU platforms

[U-Boot] [PATCH 0/3] improve build for UNIX like non GNU platforms

[Jeroen Hofstee]

The sed changes can be tested with GNU sed by sed --posix.
Tested on FreeBSD / Ubuntu.

For completeness, building with the FreeBSD arm bootstrap compiler 
needs some non u-boot related changes:
+ gcc doesn't support the -print-file-name=include, and the correct
  path needs to added manually.
+ linking fails since it also needs libc.a. Just add -lc.

[U-Boot] [PATCH 2/3] mkconfig: create CONFIG_ defines without relying on GNU extensions

[Jeroen Hofstee]

Parsing of boards.cfg relies on sed GNU extensions and fails if sed
doesn't support these. On FreeBSD this leads to the error:

sed: 1: "/=/ {s/=/\t/;q } ; { s/ ...": extra characters at the end
of q command

[U-Boot] [PATCH 3/3] rules.mk: replace GNU specific \w with POSIX equivalant

[Jeroen Hofstee]

If sed does not support the GNU \w regex extension, build attempts
lead to circular dependency warnings and finally build failure
(crc32.c not found). Build output before and after the patch on
FreeBSD is at:

maybe i havent read enough sed scripts, but i dont think ive seen "!"
used before.  how about this more straightforward replacement:
sed -e '/=/{s/=/\t/;q}' -e 's/$/\t1/'

Hi Mike,
> maybe i havent read enough sed scripts, but i dont think ive seen "!"
I took this for irony, so I triple checked:

jeroen at green-ubuntu:~$ echo config | sed -e '/=/!s/$/=1/'
config=1
jeroen at green-ubuntu:~$ echo config=2 | sed -e '/=/!s/$/=1/'
config=2

Won't work on FreeBSD since it can't quite early [afaik] (perhaps with a 
label, but gets rather ugly..)

[jeroen at blue ~]$ echo configflag | sed -e '/=/{s/=/\t/;q}' -e 's/$/\t1/'
sed: 1: "/=/{s/=/\t/;q}
": extra characters at the end of q command

Jeroen

i didnt mean "it isnt in POSIX" (because it is), i meant it as "no one
uses it, so it wont be obvious to people reading this code later as to
what's going on"

i'm not sure you've diagnosed the problem correctly.  the fact that
the output says "end of q command" indicates that FreeBSD does support
the "q" command (as required by POSIX).

perhaps the problem is that the ";" extension to separating commands
(which is not in POSIX afaics) does not work the same in FreeBSD's sed
as GNU's sed.  i imagine if you stick a ";" after the "q" command
it'll work ...

Yes, the ; does work as expected, thanks!

[jeroen at blue ~]$ echo config | sed -e '/=/{s/=/ /;q;}' -e 's/$/ 1/'
config    1
[jeroen at blue ~]$ echo config=2 | sed -e '/=/{s/=/       /;q;}' -e 's/$/ 1/'
config    2

Shall change the patch accordingly tomorrow.

Does it still work on linux as well? Did you test? If so, I'm all for it being 
merged, but just from a brief look, I see it'll be missing the TAB. Am I right?

he inlined the tab.  it isnt actually a space there.

not that it matters as this is used to create "#define CONFIG_FOO 1"
and preprocessors dont care if it's a tab or space before that "1".

yes I did build all arm boards on ubuntu (and i386?) on ubuntu. (it 
didn't build more
nor less boards). As pointed out by Mike there might be a a patch more 
closely to
the original, but I will need to test that (especially if GNU support 
it), and will do that
tomorrow (today actually CEST). So preferably take that one.

The BSD version doesn't understand \t, so it is a literal tab character. 
Can't help it.

[U-Boot] [PATCH v2 0/3] improve build for UNIX like non GNU platforms

[Jeroen Hofstee]

Changes for v2:
- updated mkconfig patch to make minimal changes and changed commit 
  message, since it now relies on GNU and BSD extensions.

Jeroen Hofstee (3):
  include/compiler.h: typedef ulong for FreeBSD
  rules.mk: replace GNU specific \w with POSIX equivalant
  mkconfig: also create CONFIG defines with BSD sed

-- 
1.7.5.4

[U-Boot] [PATCH v2 3/3] mkconfig: also create CONFIG defines with BSD sed

[Jeroen Hofstee]

Parsing of boards.cfg fails on FreeBSD with the error:

sed: 1: "/=/ {s/=/\t/;q } ; { s/ ...": extra characters at the end
of q command

BSD sed expects commands to be on seperate 'lines', hence it expects
an additional ; before the closing brackets.
BSD sed does not support \t, replaced by literal tab.
