icecc support broken?

icecc support broken?

[Felix Mellmann]

Hi,

to speed up the build process I would like to use icecc as described in 
the manual (https://docs.yoctoproject.org/singleindex.html#icecc). When 
using Yocto 4.3.1 this leads to an error while parsing the recipes:

ERROR: /Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb: 
no-pn NULL prefix
WARNING: 
/Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb: 
Exception during build_dependencies for set_icecc_env
WARNING: 
/Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb: Error 
during finalise of 
/Yocto/poky/meta/recipes-core/meta/target-sdk-provides-dummy.bb

I bisected this problem down to poky commit 3be00a (bitbake.conf: Add 
BB_HASH_CODEPARSER_VALS). Since then the problem seem to exist.
And voila when I remove "PN=no-pn" from BB_HASH_CODEPARSER_VALS in 
bitbake.conf or add

BB_HASH_CODEPARSER_VALS:remove = "PN=no-pn"

to my local.conf the recipes get parsed again and the build starts. 
Currently I'm building a vanilla yocto-4.3.1 core-image-full-cmdline for 
qemu using icecc and see if other problems are arising.

Actually I'm not able to tell what BB_HASH_CODEPARSER_VALS does and 
what's the outcome of removing this entry. But this issue shall be 
either fixed or documented within the manual.

Is icecc and the support within oe/yocto still actively maintained or is 
there any superior mechanism I'm not yet aware of?

Best regards,
Felix

I think it's not being tested due to lack of a dedicated maintainer.
If you can come up with fixes, they'll be taken, but having regression
tests requires dedicated manpower to take care of both the tests and
the fixes.

Generally icecc is not the first option when it comes to speeding up
builds: better local hardware and networked sstate infrastructure are.
