I'm not getting any linker error. Today I've compiled and tested both
i965 and iris with some patches rebased on top of commit b594796f1b8.
Does this happen with a particular version of Android?
// Tapani
It happens with oreo-x86 (Android 8.1) and pie-x86 (Android 9),
but we histocally know since Lollipop that building mesa
with asm optimization induces text relocations in libglapi shared library
and the specific problem affects 32bit builds
Here is the build log where '--warn-shared-textrel' is visible for
target libglapi.so,
please Tapani could you provide the corresponding section of your build log?
(There may be clues about the reason you are not getting the error)
I've made a celadon P build today and put the build log here:
http://tpalli.kapsi.fi/build_log.tgz
This is not complete image but builds the mesa parts, you can see that
libglapi is being built both for 32bit and 64bit in the log.
