Re: [uclibc-ng-devel] PPC e5500 build error: conflicting types for elf_vrreg_t

11 Jul 2016

Hi Andy,
ANDY KENNEDY wrote,

...
  When building using BuildRoot, I get the below errors.

https://en.wikipedia.org/wiki/PowerPC_e5500

It is a PPC64 CPU core. PPC64 is not supported in uClibc-ng, only
PowerPC.

Not sure why it is listed in Buildroot as choice for PowerPC?

best regards
 Waldemar

...
  I have not dived into determine what the problem is
yet,
 but was asking first in case anyone else has experienced
 this problem.

 Thanks,
 Andy
