Error installing wxPython on CYGWIN in Windows XP

Dear ALL:

Hope you are all enjoying a Happy New Year.

i. Down to business I am having errors in installing wxPython on CYGWIN
in
Windows XP.

ii. Have been referring to
http://gnuradio.org/redmine/wiki/gnuradio/WxPythonCygwin for
installation
guide.

iii. In the above, Steps 1, 2, 3, 4 and 4a works like a charm, I am
still
attaching the output files in case you need to refer to them.

iv. In Steps 5 i get the following warnings and error:

vi. For Step 7 there are NO “/usr/local/lib/cygwx*.dll” to be moved into

Please help. I am very much stuck.

Kind regards,

As Bob McGwier reported to the list on 3 Jan, there has been a major
update
to Cygwin, including a switch to gcc 4.3.4. I don’t know if anyone has
tried to install GNU Radio with the new version and I know that the
instructions in the wiki have not been updated for the the new version.

The immediate problem is that both winsock.h and select.h have been
included, leading to a conflict. You may be able to avoid this by
editing
build-local/lib/wx/include/msw-ansi-release-2.8/wx/setup.h so that
HAVE_SYS_SELECT_H is undefined. Of course this might just be the first
of
many such errors that are not easily fixed.

Another possibility is that another include file in gcc 4.3.4 is
including
select.h. If that is the case, we will need to see what can be done.

It should be noted that the latest Cygwin FAQ states you can’t use
winsock
functions in Cygwin (even though the winsock.h header file is included
in
the distribution). So they may have changed it so it just won’t work.

Checking out the new Cygwin is on my list of things to do, but it
probably
won’t happen soon.

Please let us know what you find.

Hi Don and ALL:

A. Managed to install and work wxWidgets but I just cannot manage
wxPython.
Anyhow the following is how I managed wxWidgets and errors found in
trying
to install wxPython.

B. Referring to http://gnuradio.org/redmine/wiki/gnuradio/WxPythonCygwin

STEP 4: ( I had to add a few more lines that I took from wxPython’s src
website
http://www.wxpython.org/BUILD.html … so now we have)

CC=“gcc -mno-cygwin -mwindows” \

CXX=“g++ -mno-cygwin -mwindows” \

LDFLAGS="-mno-cygwin -mwindows" \

…/configure \

--with-msw \

--build=i686-pc-mingw32 \

--prefix=/usr/local \

STEP 4a, 5 and 6: Remains the same.

STEP 7: (there is slight change the cygwx*.dll files are now wx*.dll
files…
so we have)

mv /usr/local/lib/wx*.dll /usr/local/bin

STEP 8: so now when you try step 8 it WORKS!

STEP 9: (But now I am stuck in STEP 9 and cannot move forward tried all
possibilities the following is the code I am using and the
output+errors…)

python setup.py build_ext --inplace WXPORT=msw COMPILER=mingw32
BUILD_GLCANVAS=0 BUILD_ACTIVEX=0 UNICODE=0 WX_CONFIG=“bash.exe -e

Thank you Don. I dont think I am capable of solving the problems faced.
Too
advanced for me. Meanwhile, I tried MSYS-MINGW and it didnt work either.
Will post the errors on another mail.

Regards.

The -mno-cygwin option says to create a native Windows version rather
than a
Cygwin version, which gets around the winsock.h vs. select.h problem.
But
it is not clear whether a non-Cygwin extension will work with the Cygwin
version of Python.

Your Cygwin version of Python wants to use select.h, which doesn’t exist
in
you non-Cygwin (i.e., -mno-cygwin) environment. Again, I don’t know if
it
is possible to build non-Cygwin extensions for a Cygwin Python.

The good news is that this problem has been reported on the wxWidgets
bug
tracker and is being worked on (see
http://trac.wxwidgets.org/ticket/11626).
The bad news, is that the supposed “correct” answer is to modify the
code
(if possible) to use posix networking calls in place of the Windows
calls.
