Cool. Just one thing - you keep saying spicec, the spicec is the name of the executable and package for the old-and-planned-to-be-phased-out-non-glib-client, so you are actually working with the spice-gtk repo now, right? git://gitorious.org/spice-gtk/spice-gtk.git? > Dynamic section at offset 0x774a4 contains 27 entries: > Tag Type Name/Value > 0x00000001 (NEEDED) Shared library: [libc.so] > 0x00000001 (NEEDED) Shared library: [libm.so] > 0x00000001 (NEEDED) Shared library: [libpixman-1.so.0] > 0x00000001 (NEEDED) Shared library: [libssl.so.1.0.0] > 0x00000001 (NEEDED) Shared library: > [libcrypto.so.1.0.0] > 0x00000001 (NEEDED) Shared library: [libjpeg.so.62] > 0x00000001 (NEEDED) Shared library: [libz.so] > 0x00000001 (NEEDED) Shared library: [libglib-2.0.so.0] > 0x00000001 (NEEDED) Shared library: [libgio-2.0.so.0] > 0x00000001 (NEEDED) Shared library: > [libgobject-2.0.so.0] > 0x00000001 (NEEDED) Shared library: > [libgmodule-2.0.so.0] > 0x00000001 (NEEDED) Shared library: > [libgthread-2.0.so.0] > 0x00000010 (SYMBOLIC) 0x0 > .... > Now comes the last adventure of Native interfaces exposing and UI building! > Regards. > > > On Wed, Mar 9, 2011 at 3:57 PM, Shuxiang Lim <[email protected]> wrote: > > > Well, I think I may try the "--with-coroutine=gthread" in spice-gtk > > configuring to walk around that... > > > > > > On Wed, Mar 9, 2011 at 11:10 AM, Shuxiang Lim <[email protected]>wrote: > > > >> Hi,I need help! > >> Now I've managed to divided spicec-gtk into two parts libspicec.so(based > >> on libpixman.so,libglib-2.0.so...No relation to X11 at all) and > >> spicec(based > >> on libspicec.so and libgtk.so...).
