Building a Kernel: Ubuntu Is Not Your Friend
Before you try building a Chumby OpenEmbedded kernel using Ubuntu, I have one bit of advice: Don’t. Use Debian.
I’ve had email from a couple of people indicating they had problems building the Chumby OE kernel under Ubuntu,
but until now I’ve not tried it myself. This came up again recently, and I thought I would check it out
for myself. I haven’t used Ubuntu much; isn’t it just Debian in OSX clothing? No?
Well the Ubuntu website says
Debian is ‘the rock upon which Ubuntu is built’, so I assume they are married or something.
Anyway, I tested with Ubuntu 12.04.1 (Precise Pangolin). The first break happens building perl:
1234567891011121314151617181920
| opmini.o: In function `Perl_load_module_nocontext':
| opmini.c:(.text+0xebac): undefined reference to `pthread_getspecific'
| collect2: ld returned 1 exit status
| make: *** [miniperl] Error 1
| + die 'oe_runmake failed'
| + oefatal 'oe_runmake failed'
| + echo FATAL: 'oe_runmake failed'
| FATAL: oe_runmake failed
| + exit 1

I found a discussion of a similar problem on a Gumstix thread which
offered the workaround of adding the following line to meta-chumby/conf/site.conf:
1
ASSUME_PROVIDED += "perl-native"
That worked and the build progressed to the next failure:
1234567891011121314151617181920

And so on… Initially I thought I would create a project fork to support Ubuntu 12, but after continuing
like this with several more breaks I could see no end in sight so I abandoned that idea.
Honestly if you are going to put a bunch of work into this project, it would be smarter to port it to the new oe-core
framework.
