[uclibc-ng-devel] uclibc-ng static libm.a support

9 Oct 2018

Hi,

I am using buildroot for my development work. I build a minimal linux for
ICOP VDX6354 board. I am using rtai-4.1 for hard realtime task for my
application.

I need to link the static libm to rtai_math.ko module to use math function
support in rtai.

When I use buildroot with uclibc I am able to generate libm.a. But when I
try to disassabmle the libm.a it lists lot of unknown symbols. Also when I
try to insert the rtai_math.ko it also reports the unknown symbols.

Is there any way to build the uclibc static libm.a with all symbols
included in it.

Buildroot Version : 2018.02.5 with rtai-4.1
Pl. comment.
