I have just released version 0.9.1 of Shed Skin, a restricted-Python (2.4-2.6) to C++ compiler. This is a maintenance release, so no new major features were added. Most interesting perhaps are optimizations for itertools.product and str.join. Other than that, it's mostly bugfixes and a new (hq2x image scaling) example. Please see the release notes for more details.
In the meantime, Paul Boddie has succeeded in getting Shed Skin 0.9 accepted into the Debian repositories, which is awesome for me personally.

Hello,
First Shed Skin is awesome!!!
Sorry if this is not the channel for ask a question.
How I can made a .o object in Shed Skin that I can link with my python embedded c code?
The make give me a library .so
Thanks,
Alex
Hello,
I installed Shed Skin 0.9.1 on my Ubuntu 11.04. After setup, I ran "shedskin test.py" which generated C code. Then, on executing "make" command, I am getting the following list of errors :
g++ -O2 -march=native -Wno-deprecated -I. -I/usr/local/lib/python2.7/dist-packages/shedskin/lib test.cpp /usr/local/lib/python2.7/dist-packages/shedskin/lib/re.cpp /usr/local/lib/python2.7/dist-packages/shedskin/lib/builtin.cpp -lgc -lpcre -o test

make: *** [test] Error 1
Looking at which, it seems like some file named "gc_allocator.h" is missing. I cannot figure out how to fix this. I have libstdc++6-4.5-dev installed.
Please help !!
I desperately want to try Shed Skin.
Thanks
sorry for the delayed reply.
@absolon: yeah, I guess the shedskin discussion group (bottom left on the homepage) would be more appropriate. please ask again there, with perhaps an example of what you're trying to do.
@koderok: you need to install the boehm garbage collector. please see the documentation for how to install this on your platform, or look for something called 'libgc'.
Hello,
After installing shedskin, I was trying to run go.py in disco-0.3 as an extension module .
shedskin -brew go.py executed fine.
make is throwing the following error. Please look into this.

@raghavalu: this is because disco 0.3 mixes ints and bools, which is not allowed anymore. please see go.py in the shedskin examples package, which changes a single line so it works again. I should probably put out a disco 0.4 with this line changed! thanks for mentioning in any case.
Thank you for your quick reply. I appreciate that. After installing I tried to open GoGui from applications menu, but its not opening up. Please suggest what to do next??
are you using windows..? the following worked for me last time:
> Label: Disco
> Command: c:\python27\python.exe disco.py
> Working directory: c:\disco
oh wait, you mean gogui doesn't work at all..? I'm afraid I can't really help with that..
I use ubuntu 12.04.
Please help to find the solution, GoGui is installed, but clicking on GoGui not opening up the game. I use ubuntu 12.04
grum :P
from a terminal, this works here:
unzip gogui-1.4.6.zip
sudo ./install.sh
gogui
to add disco, for example the version in shedskin/examples on my pc:
Label: Disco
Command: python disco.py
Working directory: /home/srepmub/shedskin/examples
I followed as you suggested, but when I type gogui in terminal its throwing following error
java.awt.HeadlessException

Exception: java.awt.HeadlessException thrown from the UncaughtExceptionHandler in thread "Thread-2"
Working directory is gogui-1.4.6
what does 'java -version' say? not openjdk?
java -version command gives following output
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.4) (7u9-2.3.4-0ubuntu1.12.04.1)
OpenJDK Server VM (build 23.2-b09, mixed mode)
if you google for this, you'll find that others see the same error.. perhaps you could try another java version? (java-sun..?) I dunno.
I'm able to run gogui finally. In disco installation instructions I see the following note
In the Program menu, connect it to engine.py. Set the board size to 9x9, and hand the first turn to the computer.
Where do I find engine.py???
good to hear!
yeah, the instructions in disco 0.3 are wrong. I uploaded a 0.4 version in the meantime with the one-line improvement and better instructions. you have to use 'python disco.py' as the command, and set the working dir to where disco.py etc. are located. don't forget to set the board to 9x9. perhaps you also have to give disco black at this point, not sure.
