.... is that the whole polyphonic sample included in pspsdk?!?!?!? omg... Seems to be a sdk related issue, like some missing stub...i guess (by your pathnames) you are not using (cygwin+)toolchain+sdk or the heimdall's win32 compiled version... Personally i think issuing compile commands directly without the use of a makefile is NOT a good idea, but i cannot say if that command line is generated by some IDE..Anyway i noticed that the error you report seems to be generated in the compilation of the library itself!! You should compile your sdk before using it...or simply change your sdk to one of the already-made and widely supported on this forum. Good luck.

thanks very much , jean.

development tool : devKitPro, dev c++.

this is the whole sample inclued in pspsdk of devKitPro tool.
i use dev c++ ide to compile it.

Personally i'm using Heimdall's sdk 0.6 for win32 (http://forums.ps2dev.org/viewtopic.php?t=9812) and NetBeans 6.0/Visual c++ express as IDE depending on my mood :)
