[Dev-C++] How to build static library with Dev-c++

[Ahmad M. <mu...@ho...>]

i'm building mysql wrapper that linking with 
-lmysqlclient -lwsock32 -lzlib 
wrapper running well, then i built static library 
using dev-c++ that linking with 
-lmysqlclient -lwsock32 -lzlib and i got 
new static library mywrapper.a 

i rename that name become libmywrapper.a then copy to lib dev-c++/lib 

but, when i used that static library that linking my application to 
-lmysqlclient -lwsock32 -lzlib -lmywrapper 

i'm getting many linker error message: 
[linker error] undefine reference to mysql_connect 

What's wrong ? 
how to build static library dan using it with dev-c++ ? 

Thanks
