[C++-sig] bjam: undefined Symbol Error

[lin yun]

Hi, folks:

I am having headache with bjam...  I am getting undefined symbol error.

Part of the Jamroot file is shown as below.  multithread_lib is defined as a
system library which is used in generating my own library img_lib.
Bag_wrapper.cpp wraps a C++ class which uses img_lib.

I am getting importError: libimg_lib.so has undefined symbol.  I have tried
for a whole day. Still have not found a way out...

Could you please help?

Thanks a lot,

Yun
