Hi, I have been trying to install qtiplot for several weeks now without success. I get the numerous "undefined reference" error messages. It seems that the qwt or qwtplot3d may be the problem. Here is a sample of the error messages I get every time I try to install qtiplot (the output is bit long but I'll post only the top most part). graph.cpp:(.text+0x1bc1d): undefined reference to
