Sorry if I'm teaching my grandmother to suck eggs.
For several flags, xfToOsOpenFlags distinguishes betwen the XF86_ and
the ordinary versions of the flags (eg XF86_O_RDWR and O_RDWR), but
xf86_libc.h has
#undef O_RDWR
#define O_RDWR XF86_O_RDWR
deliberately redefining the ordinary version for convenience -
without that redefinition your call would have to be
xf86open( "/namedpipe", XF86_O_RDONLY | XF86_O_NONBLOCK );
I take it that you have verified that that twisty maze of header files
is correctly negotiated in your case ?
The only other thing I can can suggest is to try a static build (
#define DoLoadableServer NO
in xc/config/cf/host.def). Not useful for a production version, but it
might help to track the bug down if we knew whether to blame the module
loader or not ?
