I am trying to build an application from under Linux for windows, using M cross environment (MXE), that is to say, Mingw. However I have run into a problem: references to functions from the library that I am trying to use remained unresolved.
Here is command line output:

Meanwhile in /home/truskov/development/lprsdk/LPR/bin/ are liblpr.lib and liblpr.dll, that do contain desired functions (in visual studio there is no problem in linking to them). What could be the reason for this? Could msvc compiler be to blame for it? (.lib and .dll were compiled in Visual Studio).
