[yocto] Sysroot bug in bitbake or wrong configuration?

[Svein Seldal]

I have the spu-image.bb recipe below, and running on Pyro, the recipe 
behaves differently if the recipe is run on a fresh system with no 
sstate elements, compared to a system that has a sstate cache present.

The failure is that the spu-image required the host tool "uuidgen", and 
thus has DEPENDS on "util-linux-native". When the -c cleanall spu-image 
is run prior to building spu-image, the recipe sysroot is properly 
initialized with util-linux-native and uuidgen is available in the task 
functions.

If -c clean is run prior to build, or simply by deleting tmp, the 
sysroot will not be properly initialized and uuidgen is not available 
and the recipe fails

Is this a bug in bitbake or am I missing something in my recipe?


Best regards,
Svein Seldal

# 1) Running works fine
#   		bitbake -v spu-image |tee log1.txt
#   		cat log1.txt | grep -2 uuidgen
#
# 2) Cleaning
#   		bitbake -c clean spu-image
#
# 3) Rebuilding -- now fails
#   		bitbake -v spu-image |tee log2.txt
#   		cat log2.txt | grep -2 uuidgen
#
# 4) Sstate cleaning
#   		bitbake -c cleanall spu-image
#
# 5) Works again:
#   		bitbake -v spu-image |tee log3.txt
#   		cat log3.txt | grep -2 uuidgen
