The manual states that I on a distribution level can add the following: INHERIT_DISTRO += "icecc" ICECC_DISABLED ??= "1" This will make sure my builders use the same sstate signatures regardless if they use icecc or not. The way I did it to test was to create my own distro layer, called mydist, that inherits from Poky. $ cat ../meta-mydist/conf/distro/mydist.conf require conf/distro/poky.conf DISTRO = "mydist" DISTRO_NAME = "MyDist" INHERIT_DISTRO += "icecc" ICECC_DISABLED ??= "1" In my bblayers.conf I added this layer directly after the meta-yocto layer. But with this addition my build environment will not work anymore. What happens is that the variable INHERIT_DISTRO is overwritten because my layer is picked before the poky/meta/conf/distro/defaultsetup.conf. I get the same behaviour if i edit the poky.conf and not use my own distro. $ bitbake core-image-base -e ... # # $INHERIT_DISTRO [3 operations] # append /work/yocto/course/meta-mydist/conf/distro/mydist.conf:6 # "icecc" # set? /work/yocto/course/poky/meta/conf/distro/defaultsetup.conf:22 # "debian devshell sstate license" # set /work/yocto/course/poky/meta/conf/documentation.conf:226 # [doc] "Lists classes that will be inherited at the distribution level. It is unlikely that you want to edit this variable." # computed: # " icecc" INHERIT_DISTRO=" icecc" # ... I would like some clarification about how to add the icecc on distro level and make it working. 46681 1 bluelightning 2014-10-30 15:19:13 +0000 Martin would you be able to help advise on how we should adjust the documentation here? 48137 2 Martin.Jansa 2015-01-21 12:20:58 +0000 (In reply to comment #1) > Martin would you be able to help advise on how we should adjust the > documentation here? setting INHERIT_DISTRO value isn't specific to icecc INHERIT_DISTRO_append = " icecc" should work if you're setting it in config file parsed before defaultsetup.conf (immediate append '+=' just prevents '?=' from defaultsetup.conf to be applied) 48453 3 srifenbark 2015-01-30 19:37:11 +0000 Hi Peter, I have implemented the change suggested by Martin to three manual development branches (1.6.x, 1.7.x and 1.8). You can see the fix at http://www.yoctoproject.org/docs/1.6.2/ref-manual/ref-manual.html#ref-classes-icecc. Marking the bug as RESOLVED and setting the documentation flag to "done." Thanks, Scott
