"tiff" build seems to be OK with Ubuntu 11.04 i686.
what is your BB_NUMBER_THREADS setting ?
Here (on 2 different hosts/distro/arch but with an i7 CPU in both
cases) if I
set it over 4, I often (always with a value of 8) meet problems with
c++
includes during build from scratch. 4 seems the magic value which never
trigger the problem.
To help me get further data points on this issue, are you using rm_work?
Do the recent changes in master help (the bitbake sstate/task_skip()
ones in particular)? I've not been able to reproduce this :(
yes that was with rm_work, I still need to test with current head.

I have tried Ubuntu 11.10 x64 once more.
This time with
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "j4".
Not exactly the same symptoms , but similar.
This time, the "string" header is not found.

Tried compiling manually.
It appears to me that the "--sysroot" directive gets ignored.
--sysroot=/media/SSD/OE_core/setup-scripts/build/tmp-angstrom_2010_x-eglibc/sysroots/qemuarm
I manually added "-I/usr/include/c++", but that did not help
I then copied "string" to the compile directory, and then the
compile continued /until missing the next include file)
compiler built:
arm-angstrom-linux-gnueabi-g++ --version

The same build works on Ubuntu 11.04 i686.
