In our scenario the text relocations happen when building android-x86 32bit
user space on 32bit kernel,
in your build log you are building x86_64 target, where we also don't get
any issue.
Could you please try, when you have time (and no hurry) to build Celadon P
32bit user space on 32bit kernel?
I'd really like to use asm optimizations if now possible
As additional info here is the android-x86-development thread were all
attempst to use -fPIC, -DPIC were failed,
in our experience the 32bit user space will just refuse to use the
libglapi.so with Text Relocations:
https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/android-x86-devel/qO9gtkyE_PU/9fUan0VjCAAJ
Then if Celadon P can build libglapi.so without Text Relocations for 32bit
user space on 32bit kernel,
how is it done? We have this problem since Android nougat-x86
Thanks (and sorry in case I'm doing something wrong)
