Error on Build of wxPython

GNU Radio
1

I’m trying to build and setup wxPython, and at step 9 of the wiki
instructions (http://gnuradio.org/trac/wiki/wxPythonCygwin) I get a g++
error, as apparently a library isn’t linking.

Some background: I’m installing on Cygwin on Windows XP, and have
followed the instructions to use binutils 20080523-1.

(the first line is the command)

Any help?

Some background: I’m installing on Cygwin on Windows XP, and have

[etc.]

Once again, it appears that a change in the wxPython release has broken
the
Cygwin build. I don’t know how it is supposed to work, but I made it
work
by doing the following:

After running …/configure, find the file
build-local/lib/wx/include/msw-ansi-release-2.8/wx/setup.h and after the
line:

#define wxUSE_DATEPICKCTRL 1

add another line:

#define wxUSE_DATEPICKCTRL_GENERIC 1

then continue with the directions in the wiki.

Don,
I’m glad people smarter about these things than me are ready to help.
That did the trick. It seems to be installed properly now.
