 +Icecc is outdated:
 +
 +  * Latest release is 1.4.0 (2022) which doesn't include lots of nice fixes and features.
 +    * Thread [[https://github.com/icecc/icecream/issues/586|Overall status of the project #586]] points to use [[https://github.com/mozilla/sccache/|sccache]] instead of icecream
 +  * ''icecc.bbclass'' is not maintained and lack support of new Yocto features, generating a lot of problems (i.e. clang)
 +    *  '-fno-diagnostics-show-caret' in clang: [[https://github.com/kraj/meta-clang/issues/806|dunfell: compiler-rt: invalid argument causes sanity check to fail
 +#806]]
 +  * many forks with patches exists: [[https://github.com/icecc/icecream/compare/master...felix642:icecream:master|]]
 +  * [[https://mbition.yocto.co.kr/entry/Intermediate-results-of-icecc-icecream-testing-on-Yocto|Intermediate results of icecc (icecream) testing on Yocto]]
 +  * **YOCTO drops icecc.bbclass:**  [[https://git.yoctoproject.org/poky/commit/?id=ba4fd5229893a24ef1f305c0b04facf2329b16df|classes/recipes-devtools: Drop icecc from OE-Core]]
 + 
 +  * Issues:

 +
 +**NOTE:** icecc daemon has to be run on localhost. Instead of this all jobs will be spawned locally with i.e. ''-j 100''
 +
 <code bash>sudo apt-get install patchelf icecc icecc-monitor</code> <code bash>sudo apt-get install patchelf icecc icecc-monitor</code>
 +
 +Example performance gain (''make -j14'' vs ''make -j 100''):
 +
 +<code bash>
 +bitbake nativesdk-qemu
 +
 +#
 +# ICECC_PARALLEL_MAKE = "-j 100"
 +#
 +bitbake nativesdk-qemu -c cleansstate
 +time bitbake nativesdk-qemu
 +
 +real 3m58.270s
 +user 0m0.942s
 +sys 0m0.153s
 +
 +#
 +# ICECC_DISABLED = "1"
 +#
 +bitbake nativesdk-qemu -c cleansstate
 +time bitbake nativesdk-qemu
 +
 +real 7m21.235s
