I am doing a cross-compile, and I'm getting some undefined symbols.

I would like to have some idea about how I can troubleshoot this.
I am not sure how I can be sure I am picking up the right include-files and
libaries etc:
export CC=arm-linux-g++
export CXX=arm-linux-g++
export LDFLAGS="-lrt"
./configure --host=arm-linux-uclibcgnueabi ---target=arm-linux-uclibcgnueabi
-disable-shared --disable-thread
