g++: undefined reference to `_imp___ZN5pluma13Plxxxx

I want to compile project "pluma".I use mingw，and open this project with codeblock with default cbp.The first two project go well, with following log:

mingw32-g++.exe -std=c++0x -Wall -DPLUMA_EXPORTS -g -O0 -I..\..\include -I..\..\src -c F:\workspace\mec\Pluma-1.1\src\Pluma\Dir.cpp -o ..\..\ztemp\mingw\debug\src\Pluma\Dir.omingw32-g++.exe -std=c++0x -Wall -DPLUMA_EXPORTS -g -O0 -I..\..\include -I..\..\src -c F:\workspace\mec\Pluma-1.1\src\Pluma\DLibrary.cpp -o ..\..\ztemp\mingw\debug\src\Pluma\DLibrary.omingw32-g++.exe -std=c++0x -Wall -DPLUMA_EXPORTS -g -O0 -I..\..\include -I..\..\src -c F:\workspace\mec\Pluma-1.1\src\Pluma\Host.cpp -o ..\..\ztemp\mingw\debug\src\Pluma\Host.omingw32-g++.exe -std=c++0x -Wall -DPLUMA_EXPORTS -g -O0 -I..\..\include -I..\..\src -c F:\workspace\mec\Pluma-1.1\src\Pluma\PluginManager.cpp -o ..\..\ztemp\mingw\debug\src\Pluma\PluginManager.omingw32-g++.exe -std=c++0x -Wall -DPLUMA_EXPORTS -g -O0 -I..\..\include -I..\..\src -c F:\workspace\mec\Pluma-1.1\src\Pluma\Provider.cpp -o ..\..\ztemp\mingw\debug\src\Pluma\Provider.omingw32-g++.exe -shared  -Wl,--out-implib=..\..\lib\libpluma-d.a -Wl,--dll  ..\..\ztemp\mingw\debug\src\Pluma\Dir.o ..\..\ztemp\mingw\debug\src\Pluma\DLibrary.o ..\..\ztemp\mingw\debug\src\Pluma\Host.o ..\..\ztemp\mingw\debug\src\Pluma\PluginManager.o ..\..\ztemp\mingw\debug\src\Pluma\Provider.o  -o ..\..\lib\pluma-d.dll  Output file is ..\..\lib\pluma-d.dll with size 1.36 MBProcess terminated with status 0 (0 minute(s), 1 second(s))0 error(s), 0 warning(s) (0 minute(s), 1 second(s))

But when I compile the third project and link with the lib generated before.I get following log:

However,I use "nm libpluma-d.a" to check out the symbols，I see:

00000000 I __imp___ZN5pluma13PluginManager14loadFromFolderERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEb00000000 I __imp___ZN5pluma13PluginManager12registerTypeERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEjj00000000 I __imp___ZNK5pluma13PluginManager12getProvidersERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

These symbols are existed, but only they are prefixed with "__imp".There is another "_" in the prefix.Is this the problem?How can I fix it?
