Yocto system common build errors

1 Common build errors

1.1 Check-sum

Sometime you will get an error as listed below. The reason is due to re packaging on the server of the provider. locate the pacakage bb file

$ find ../sources/ -name evtest*

./meta-openembedded/meta-oe/recipes-support/evtest ./meta-openembedded/meta-oe/recipes-support/evtest/

edit the pacakage

$ gedit ./meta-openembedded/meta-oe/recipes-support/evtest/

And replace: SRC_URI[archive.md5sum] = "770d6af03affe976bdbe3ad1a922c973" SRC_URI[archive.sha256sum] = "3d34123c68014dae6f7c19144ef79ea2915fa7a2f89ea35ca375a9cf9e191473" With: SRC_URI[archive.md5sum] = "0ef3fe5e20fa2dee8994827d48482902" SRC_URI[archive.sha256sum] = "6e93ef54f0aa7d263f5486ce4a14cac53cf50036bfd20cf045fef2b27ee6664b"

1.1.1 Error log example

ERROR: Fetcher failure for URL: ';name=archive'. Checksum mismatch! File: '/ws/variscite/yocto_dl_dora/evtest-1.25.tar.bz2' has md5 checksum 0ef3fe5e20fa2dee8994827d48482902 when 770d6af03affe976bdbe3ad1a922c973 was expected File: '/ws/variscite/yocto_dl_dora/evtest-1.25.tar.bz2' has sha256 checksum 6e93ef54f0aa7d263f5486ce4a14cac53cf50036bfd20cf045fef2b27ee6664b when 3d34123c68014dae6f7c19144ef79ea2915fa7a2f89ea35ca375a9cf9e191473 was expected If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe: SRC_URI[archive.md5sum] = "0ef3fe5e20fa2dee8994827d48482902" SRC_URI[archive.sha256sum] = "6e93ef54f0aa7d263f5486ce4a14cac53cf50036bfd20cf045fef2b27ee6664b" Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.

1.2 Can't find package

Due to server maintenance sometime it will fail to fetch the source. search the exact file name and version and download it from other source into your download directory.
