Hi,

See notes on http://cygwin.com/lists.html


After running the command (i had to run it via dash), the error now looks like this:

$ make -j2
ldd: /lib/libreadline.a: Permission denied

no idea, look for permission on your file or try make -j1

check dllimport usage on the source. Eventually look cygwin python source for any patch specifically used.

http://cygwin.com/cgi-bin2/package-cat.cgi?file=libncurses-devel%2Flibncurses-devel-5.7-18&grep=curses.h


as the file is on
/usr/include/ncurses/curses.h

check any
#include "curses.h"
and change to "ncurses/curses.h"

Python build finished, but the necessary bits to build these modules
were not found:
_tkinter           bsddb185           linuxaudiodev
nis                ossaudiodev        spwd
sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for
the module's name.

Failed to build these modules:
_curses            _curses_panel      _io

Hi all,

I installed Cygwin an hour ago, and I'm on Windows7 Pro.



It is a fork issue, so you need to run rebaseall.


As it seems Python run itself during the build you
need to add the dll's just created to the rebase list

$ find /usr/local -name "*.dll"> local_list

and from dash shell

$ rebaseall -T local_list

after that I presume the make should be able to complete the job.

Marco
