some erros while using qlua

[chenmeiya]

I am a new to torch. When I install qtlua, there are not any error. Additionally, I can find the path of qlua, but get wrong if enter the qlua, just like bellow. I am confused about the libreadline.so.7, could anyone give some solutions? Thanks a lot.

cmy@cmy-System-Product-Name:/torch$ which qlua
/home/cmy/torch/install/bin/qlua
cmy@cmy-System-Product-Name:/torch$ qlua
qlua: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
