Hi,Ankur

I compiled app w3cam successful. But I achieve it in a "stupid" way.

You told me to ".. get where libpng.a is installed (if other that default path), specify its path in LDFLAGS in your Makefile manually or though ./configure.".But after specifying LDFLAGS, compiling still failed. That means the library dir did not setted correctly. So I tried another method..copy all *.a(library needed ) to the dir the makefile "specify". After done it, compiling succeed. Then i downloaded the zImage into my DE2 board. I can run the app "vidcat". Although another problem appears again,I think the problem about app w3cam has been solved.

Well, next i will try to make clear how to specify the path in LDFLAGS. if I find some useful details ,i will share.

Thanks to Ankur.
