Link Error with trunk

[Gerald Brandt]

Hi,

Just upgraded latest trunk today. My project is now getting a link
error, so something changed.

/home/gbr/downloads/wxWidgets/wxWidgets/build-release/lib/libwx_gtk2u_core-3.1.a(corelib_displayx11.o):
In function `wxXF86VidMode_GetCurrentMode(_XDisplay*, int)':

This is probably related to wxX11 GSoC project merge, but I don't see what
exactly could have broken it nor even why is it broken, exactly.

So apparently configure detects Xxf86vm library and headers in your build.
In this case, it should link with libXxf86vm.so which is supposed to
contain this (and other missing) function(s). Do you see this library in
the link command?

Hi,

It's not showing up in my Code::Blocks build. Code::Blocks calls
wx-config to get the libs.

Interestingly, if I do wx-config --libs from the command line, it's
there. Maybe code:blocks is doing some caching.

Thanks for the pointer.
