Hi John,

This is the "simplified" output:

c++ -o configtool <lots-of-files.o>  -LTCLDIR_use_system/lib -L/usr/local/lib
-l<other-libs>... -ltcl `/usr/local/bin/wx-config --libs std,gizmos`
/usr/bin/ld: /usr/local/lib/libwx_gtk2_core-2.8.a(corelib_utilsx11.o):
undefined reference to symbol 'XGetWindowAttributes'
/usr/bin/ld: note: 'XGetWindowAttributes' is defined in DSO
/usr/lib/libX11.so.6 so try adding it to the linker command line
/usr/lib/libX11.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [/<my-build -folder>] Error 1

I compiled this in Fedora14+wxGTK-2.8.12 and Fedora15+wxGTK-2.8.8, and I
get the same problem in both of them (both wxGTK were compiled from
sources and installed in /usr/local, I know that /usr/local/bin is in
the PATH, but my LD_LIBRARY_PATH is empty, as I rely in the config
scripts for wx and tcl).

If you want the full link command (two or three screens), let me know,
and I'll recompile.

Cheers
