Re: [Cppcms-users] static linking error

[陈抒 <csf...@gm...>]

I made much progress. It's about dependency order. Because if A needs B, A
 should appear in front of B.
I delete all libraries started with -l in the command, and add one, then
link it. will see linker complains some thing missed. Then I add one.
Finally, I link my app successfully. Below is the command which is much
longer than what I expected.

 /usr/bin/c++ -g

But I still get some warning messages, It seems it is another problem for
me. Any idea?
