<div>Hi Josh,</div> <div>     I have updated xftdpy-xcb.c for initializing the client version number(set major=0,minor=3) when query render verion, according to the one in xcb-demo/rendertest.c.     If you still run into segfaults or hangs, maybe some default-values are wrong,which originally got by XGetDefault. I just hard-code them,you can modify them to fit yourself then try again.     Please tell me if you got xft running well on xcb.</div> <div> </div> <div>--Jianjun  </div> <div>On 10/27/06, Josh Triplett <<a href="mailto:josh@freedesktop.org">josh@freedesktop.org</a>> wrote:</div> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Yang JianJun wrote: > On 10/27/06, Josh Triplett <<a href="mailto:josh@freedesktop.org">josh@freedesktop.org </a>> wrote: >> Yang JianJun wrote: >>>         I have ported libXft and Pango to XCB backend, It works well >> now. >>> For some reasons I picked Pango-1.8 which use Xft for rendering instead >> of >>> cairo.

Can you run it then? I did indeed have an older xcb-util checkout; good catch.  I updated to a current checkout, and your libXft now builds with --enable-xcb.  However, when I attempt to run programs against it, it either segfaults or hangs. I noticed a few warnings while building; looking into them, some relate to variables initialized by the commented-out calls to XGetDefault, but I also noticed this one, in _XftDisplayInfoGet from line 141 of xftdpy-xcb.c onward:    if (info->hasRender)    {                        int major, minor;                        ver_rep = xcb_render_query_version_reply (dpy,xcb_render_query_version (dpy,major, minor),NULL);                        major = ver_rep->major_version;                        minor = ver_rep->minor_version;                        if (major < 0 || (major == 0 && minor <= 2))                            info->use_free_glyphs = FcFalse; This code passes the uninitialized local variables major and minor to xcb_render_query_version as the client-supported major and minor Render version, before using them to hold the negotiated version. Also, the point about libpixman deprecation didn't relate to the error messages. - Josh Triplett </blockquote>
