Как собрать Port Audio, используя mingw и msys?

У меня проблема со сборкой Port Audio на машине с Windows. Я следую этому уроку: http://portaudio.com/docs/v19-doxydocs/compile_windows_mingw.html

Бег make после ./configure запускает процесс сборки и, наконец, выводит это сообщение, и на этом процесс сборки останавливается.

/bin/sh ./libtool --mode=link gcc  -shared -rpath /usr/local/lib -no-undefined -

*** Warning: linker path does not have real file for library -lwinmm.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libwinmm but no candidates were found. (...for file magic test)
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.

*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.

Я новичок в создании библиотек, поэтому я не понимаю, что здесь не так.
Любая помощь приветствуется.
