Unless taken proper care of the result is very often a "taskhash mismatch" error. However, the root cause for taskhash mismatch errors is often extremely difficult to find. My personal experience is that workdays have been lost due to them. On a general level, bitbake is missing methods for efficiently identifying "taskhash mismatch" errors. The root cause might be poorly or wrongly written recipes, but the tools should be able to highlight where the failure is originating from. 75827 1 richard.purdie 2017-08-13 12:52:59 +0000 https://www.kc8apf.net/2017/01/tired-of-taskhash-mismatch/ has some info about this. 75828 2 richard.purdie 2017-08-13 12:53:15 +0000 https://wiki.yoctoproject.org/wiki/TipsAndTricks/Understanding_what_changed_(diffsigs_etc) 96830 3 randy.macleod 2023-10-24 14:24:26 +0000 Bulk move from 4.99 or 0.00 to 5.99 104764 4 richard.purdie 2026-03-20 14:05:14 +0000 Significant work was done on this during the STF projects. If there is a specific case where it is still hard to identify the cause, we should document the specific cases so we can find ways to improve them. Resolve this bug as the base work was completed.
