I also think,there may be problem with pango/pangoft2. But I have no clues now where is the problem exactly. > OK, please tell me the versions of component softwares: > GLib, Cairo and Pango, and configuration options you used Software and its versions. GLib: 1.17.6 ( config with --with-libiconv --enable-iconv-cache--disable-selinux --disable-fam --disable-xattr ) Cairo: 1.8.10 ( config with --enable-directfb=yes --enable-xcb=no --without-x --disable-xlib --disable-xlib-xrender --disable-win32 --disable-pdf --disable-ps --disable-svg --enable-png ) Pango: 1.22.1 ( config with --without-x ) Though, I have updated cairo-1.10.0. But did not work. -Manoj On Mon, Nov 29, 2010 at 3:49 PM, <mpsuz...@hiroshima-u.ac.jp> wrote: > Hi, > > Thank you very much for screen shots.
