[Buildroot] Analysis of defconfig build failures

Sun Aug 12 15:01:38 UTC 2018

Hello,

Today, I analyzed the defconfig build failures of
https://gitlab.com/buildroot.org/buildroot/pipelines/27617503. I fixed
a number of them, except two:

 - Problem of U-Boot failing to build due to a clash between the libfdt
   headers part of U-Boot, and the libfdt headers installed by our
   host-dtc package. We already made several changes in uboot.mk to try
   to fix this, but it still doesn't work properly.

   Does anybody has an idea ? Thomas DS, you already worked on this
   issue (you're the author of commit
   baae5156ce37e8b2775f04710f7d1c8e97e4114c). Any clue ?

   The problem is fixed in U-Boot 2018.01 but present in 2017.11.
   However, we have a number of vendor-provided U-Boot, and it's not
   necessarily easy to upgrade all defconfigs to use at least 2018.01.

 - Problem of recent U-Boot that needs host-bison to build kconfig.
   Yann posted a patch series to make bison and flex hard requirements
   of Buildroot. Do we want to go this way ?

Here is the detailed list of the defconfig build failures:

 - Filesystem too small

 - U-Boot needs Bison

   The proposal from Yann in
   http://patchwork.ozlabs.org/project/buildroot/list/?series=59260 is
   to make flex and bison hard requirements of Buildroot. We need to
   take a decision on this.

 - Kernel needs OpenSSL

 - Failed because of Gitlab issues. I restarted them, but didn't wait
   for their new build to complete.
