can't resolve symbol 'dl_iterate_phdr'

[arc1986]

I tried cross compiled on MIPS and the static lib was generated fine

./mips-linux-gcc --version
mips-linux-xgcc (Realtek RSDK-1.5.6p2) 4.4.6
Copyright (C) 2010 Free Software Foundation, Inc.
ls
../rsdk-1.5.6-5281-EB-2.6.30-0.9.30.3-131105/lib/libbacktrace.a

But getting below error while executing the below 'bt' same code (statically linked with libbacktrace.a)
https://github.com/ErwanLegrand/libbacktrace/blob/master/examples/bt.c

output/bt: ELF 32-bit MSB executable, MIPS, MIPS-I version 1 (SYSV), dynamically linked, interpreter /lib/ld-uClibc.so.0, with debug_info, not stripped
./bt
can't resolve symbol 'dl_iterate_phdr'

That's odd. The libbacktrace configure script checks whether dl_iterate_phdr exists, and only calls it if it is present on the system. Why does the configure script find dl_iterate_phdr if it is not present on your system?

[arc1986]

Yeah, I re-checked it, 'dl_iterate_phdr' is present in the system. But not sure why I'm getting that error only if I ran 'bt' code,

[arc1986]

the error is gone when I compiled the code with '-static', however now getting a segmentaion fault,

I have no idea what is happening here. Is this still a problem? Thanks.
