#32 mingw python can not run in interactive mode
I found this issue months ago (again, sorry for late). I've installed msys-python2, msys-python3, mingw-x86_64-python2, mingw-x86_64-python3. Some of them are installed because of dependency. This days, I mainly works with mingw-x86_64-python2 (Because msys version do not have a pip package :P).
At first, none of those python works correctly. For the msys version, run python/python2/python2.7/python3/python3.3/python3.3m will back to bash without any error message (This issue does not exist any more in the up-to-date version).
But for the mingw version, issue is still there. Type python(2 or 3) in bash or cmd then enter, python displays its version information then the prompt >>>, then quit without error. Running python with - got the same result. These days I used the special file in windows for an interactive python: python con as a workaround.
This issue is related to ncurses. We disscuss with ncurses developers about fixing it. As workaround we can rebuild python without readline/ncurses
I hate to admit that this is a good idea for now.

#32Hello!
I wrote using the google translation this article(- -)
I'm sorry if there is inadequate representation....
You can type with python -i, and can be avoided by using the winpty this problem.
winpty will help interactively most applications.
https://github.com/rprichard/winpty/
X64bit does not exist unfortunately, you must build it yourself.
And I have prepared a set of patches for building winpty here.
Please working in msys2-dev on always.
configure
fix
i686-pc-mingw32-g++ -> =x86_64-pc-mingw32-g++
main.cc
add to 220 line
extern "C" int
cygwin_conv_to_win32_path (const char path, char win32_path)
{
return cygwin_conv_path (CCP_POSIX_TO_WIN_A | CCP_RELATIVE, path, win32_path,
MAX_PATH);
}
However, it has confirmed the path in the "/usr/bin/xx" in msys,
but does not recognize If you do not specify an absolute path in msys2.
Fix it for me might be bad.
example:
command input
console c:/msys64/bin/python
^
input full_path
registration "$HOME/.bashrc"
alias python='console c:/msys64/bin/python'

When I build it, I get error message:
$ ./configure
uname -s identifies a MSYS environment.
Error: could not find Cygwin/MSYS G++ compiler. One of these should be in your PATH:
* i686-pc-msys-g++
I have installed package "mingw32/mingw-w64-i686-gcc 4.8.2-7", should i install package "msys/gcc 4.8.2-2 (msys2-devel)"?
What's the different between mingw32 gcc and msys gcc?
Last edit: owlcn 2014-04-18
First, why you write it in issue about Python?
Second, to use appropriate mingw compiler you need start MSYS2 from mingw32_shell.bat or mingw64_shell.bat. In your case you need use mingw32_shell.bat
The same issue when i run mingw-w64-i686-lua, I must input lua -i to enter interactive mode.
I start MSYS2 from mingw32_shell.bat.
ncurses is still broken...
thank you~
I want to build winpty to have a test, but i get the error message, what's wrong
Should I install msys gcc?
What error?
I get error message:
$ ./configure
uname -s identifies a MSYS environment.
Error: could not find Cygwin/MSYS G++ compiler. One of these should be in your PATH:
* i686-pc-msys-g++
./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32
But you should use the msys2 pacman build system. Then it is just
makepkg-mingw from the right folder.

#32I'm sorry, owlcn's,
./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32
If you can not build this command,
home->developers->x32(or x64)-msys2-develop-20131022.tar.xz
Please download and uncompress it.
It should be successful if build anything without changing the setting of msys side.
The bottom line, it is to use the g++ of msys/bin.
However, please do not forget to change the description of the "Configure".
src/configure

Build as you will succeed if. good luck!
Alexx83's, I'm sorry to bother.
I think the combination of ncurses and readline is, a bad combination in mingw.
It will be a little better if PDCurses, but it does not provide a complete operation.
fix for the win32 has entered in the ncurses-5.9-20140412.patch, but it was still bad after all.

Hi LiTuX, psxxx, owlcn,
psxxx:
The old MSYS2 developer package tarball you used is now redundant since we now use Pacman to manage packages. Alexey, would it be ok to remove these so no one tries to use them in future?
everyone:
You want Python/lua/whatever without ncurses support. We agree that ncurses is currently broken and do apologise for the lack of interactive support for these tools under MSYS2. Rest assured, a fix is being worked on by someone who knows ncurses and Windows console programming very well.
In the meantime, here are the instructions to take you from not having MSYS2 on your computer to building your own Python2/3 package, and then finally installing it, so that you can try to remove or fix ncurses support, or attempt to add support for an alternative such as PDCurses.
Download and extract http://garr.dl.sourceforge.net/project/msys2/Base/x86_64/msys2-base-x86_64-20140216.tar.xz using 7-zip. For the purposes of this, I'm extracting it to C:\temp so change these instructions to taste.
From Windows Explorer, go to C:\temp\msys64 and run msys2_shell.bat
From the bash prompt, type "exit", then re-run msys2_shell.bat
From the bash prompt, type "pacman -Syu". It should ask ":: Proceed with installation? [Y/n]", enter Y/y or press the Return Key.
.. wait for the base packages to get updated to the latest versions. You will see some scary looking messages, don't worry. Once it's finished, type "exit" again.
Run autorebase.bat, then re-run msys2_shell.bat.
Install your base development tools.
From bash prompt, run "pacman -S autoconf make automake-wrapper patch git gettext". Enter "all" or press Return Key. Enter Y/y or press the Return Key. There's a meta-package called base-devel that you could install instead but that will install more than you strictly need ("pacman -S base-devel"). Exit bash again with "exit", then re-run autorebase.bat (any time you install new MSYS2 packages - as opposed to MinGW-w64 ones you need to repeat this process to make sure the MSYS2 DLLs are all shuffled to co-exist happily).
To install the x86_64 toolchain and Python dependencies, run:
"pacman -S mingw-w64-x86_64-toolchain mingw-w64-x86_64-xz mingw-w64-x86_64-pkg-config"
To install the i686 toolchain and Python dependencies, run:
"pacman -S mingw-w64-i686-toolchain mingw-w64-i686-xz mingw-w64-i686-pkg-config"
To get the latest version of the recipes for all the MinGW-w64 packages run:
"git clone https://github.com/Alexpux/MINGW-packages"
pushd MINGW-packages/mingw-w64-python3
.. At this point you would change PKGBUILD and make patches (and add them to PKBUILD) if necessary.
makepkg-mingw -L --nocheck
.. To install the package(s):
pacman -U mingw-w64-*.xz
popd
pushd MINGW-packages/mingw-w64-python2
.. At this point you would change PKGBUILD .. etc .. etc
makepkg-mingw -L --nocheck
.. To install the package(s):
pacman -U mingw-w64-*.xz
popd
One thing I should add, if you change patches or add some then you
need to add any new ones to the "source" array in PKGBUILD. In either
case, you then need to regenerate the embedded checksums in there. To
do this run "makepkg-g" and copy/paste the new array into PKGBUILD

#32Hi, Ray Donnelly
This msys2-dev environment allow us to build the tool was not possible in mingw-w64 + msys.
It is, for example, include / cygwin, include / sys / socket.h, etc ...
example:whois
It must be better is going to distinguish depending on the situation the neighborhood.
In other words I see it this way.
Was given the material by msys2-dev team we. It is our job or how to utilize them.
Good luck and thanks to this project!
I thank you for reading it through.

Python interactive mode partially solved by readline-6.2.005-3 package. Try it
