linker error with opencv2.1 in devcpp windows 7-Collection of common programming errors

i have opencv2.1 in devcpp environment. it works perfectly. then i recently tried installing a wavelet library downloaded from here.

now i tried compiling an example program in the library (i created a new project and inserted the example file into it. i also added all corresponding libraries and includeed files in the downloaded library) but it keeps on returning the following two errors:

[Linker error] undefined reference to cv::Mat::Mat(_IplImage const*, bool) [Linker error] undefined reference to cv::fastFree(void*) ld returned 1 exit status

D:\Makefile.win [Build Error] [Project1.exe] Error 1

please someone help me..
