Hey,
In my program, I want to check that the xserver-xorg version is>=
1.8.0. What way to do this is advised:
At runtime using XVendorRelease(), or do there exist different
releases with inconsistent numbering ? And should this be combined
with a literal match on XServerVendor() ?
At configuration time, PKG_CHECK_MODULES(XSERVER18, [xorg-server>=
1.8.0], FOO=bar, FOO=baz). But what if you want to discriminate
different versions, multiple PKG_CHECK_MODULES ? This would swamp the
number of _LIBS and _CFLAGS options...
Also, PKG_CHECK_EXSISTS() seems to ignore the version I provided, and
always sets FOO=bar.
This would probably be easier to answer if you gave some indication of
why you think you should refuse people with different X servers to run
or compile your application.
Its not about refusing, its about using features:
if the xserver is 1.8 or higher, my application can write an example
xorg.conf.d snippet, otherwise it has to explain a different way of
making calibration values permanent.
xdpyinfo has a case-based section that calculates the release based on
the XServerVendor() and XVendorRelease().
I'll guess I'll go for a similar approach of strstr(ServerVendor(dpy),
"X.Org") and VendorRelease(dpy) > 10800000.
Thanks anyways,
Tias
