I use libuwind in openwrt like this :
https://github.com/openwrt/openwrt/tree/master/package/libs/libunwind
I run Gtest-trace for test, get this result:
Normal backtrace:
normal trace:

via unw_backtrace():

I run Gtest-bt for test, get this result:

SUCCESS.
I used toolchain:
mipsel-openwrt-linux-uclibc-gcc
how can solve this problem?
