Hi,

I am new in emscripten. I would like to link emscripten with some 
libraries. 
However my codes have a lot of linking errors. 
After reading 
https://github.com/kripken/emscripten/wiki/Building-Projects
I still cannot solve my problems. 

To make the question simple, I made a small hello_world example, where 
there is one class in hello_lib.h and hello_lib.cxx, and one main function 
in hello_lib_test.cxx. 

[jcheng@jcW530 hello]$ emcc  hello_lib_test.cxx -o 
hello_lib_test.bc                                                               
                                                                                
                          

[jcheng@jcW530 hello]$ emcc  hello_lib.cxx -o hello_lib.bc
[jcheng@jcW530 hello]$ emcc hello_lib.bc hello_lib_test.bc -o 
hello_lib_test.html
warning: unresolved symbol: _ZN6helloCC1Ev
warning: unresolved symbol: _ZN6helloCD1Ev

I cannot link hello_lib_test with hello_lib, and the output in 
hello_lib_test.html is not correct (it showed -1)
Is there any tutorial for this? Thanks.

best,
Jian Cheng
