I continue to explore the problem
my linux version is redhad 9,and I use command "rpm" to find how many package I have installed
I found such as freetype,fontconfig and other package is installed,but the version is lower
now I install higher version on it by tarball and have not unistall the old version,maybe it caused many problem
now i dont know how to deal with these problems
the only thing that I want to do is to install msn,but the version is lower so cant connect normally.
