I get errors such as
  undefined reference to `wxWindowList::DeleteFunction(wxWindow*)'
  undefined reference to `wxMenuItemList::DeleteFunction(wxMenuItem*)'
building code I wrote, and I can reproduce at least the second one
in a wx sample program: see below. No lmi, no mpatrol, just wx-2.6.2
and this old MinGW gcc in MSYS.

OK, I'm using
  http://prdownloads.sourceforge.net/mingw/MinGW-3.1.0-1.exe
same as you; that's gcc-3.2.3 . The MSYS DTK isn't needed, and the
problem I'm reporting should not depend on any particular version
of the shell.

OK, I'm not actually using any of those to demonstrate this problem.

I downloaded that version:
  C:/downloads[0]$md5sum wxWidgets-2.6.2.tar.bz2
  ee0aa211febd992c8540e6c9df749b51  wxWidgets-2.6.2.tar.bz2

Not used in demonstrating the 'sample' problem I'm reporting.

Here I cut and paste exactly what I did to reproduce the problem
with the wx menu sample:

Do you get the same result? Oh...look at this...it happens with
even the minimal sample:

I have another 2.6.2 build (which uses a different gcc version) in
another directory, '/c/wxWidgets-2.6.2/build_3_4_2/', and I did
'make install' with that other build. But I don't see how that can
cause this problem. Reformatting the above linker command for clarity:

  g++ -o minimal.exe minimal_sample_rc.o  minimal_minimal.o
  -L../../lib -mwindows
  -lwx_mswd-2.6 -lwxpngd-2.6 -lwxzlibd-2.6 -lwxexpatd-2.6
  -Wl,--version-script,../../version-script
  -lrpcrt4 -loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32
  -lcomctl32 -lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32

The only library search path is '-L../../lib', so no other build
should interfere, right?

I haven't modified the wx-2.6.2 sources except to remove five
stray semicolons:

  http://lists.gnu.org/archive/html/lmi/2006-03/msg00023.html
No, wait--I didn't even do that in '/c/wxWidgets-2.6.2/'; I
did it only in the copy I installed in '/usr/local/include'.
