RE: Question regarding CaChannel -v1.6 compilation using python-3.2 onlinux 86-64 bit

["Wang Xiaoqiang" <Xiaoqiang.Wang@psi.ch>]

Hi,

 

In the moment it is Python 2 only. The barrier is in both C extension and Python source.

Because our standard scientif linux 5 comes with python2.4, and python 3 is not even in SL6. The python3 compatible request is rather low on my side.
That said, I did make a try to make it compile against python 3. I did not go futher than making it compile. If that is definitely requested, I will try to finish it.

 

The above is only speaking about myself. It is important to have opinions from Noboru Yamamoto-san.

 

Best,

Xiaoqiang

Subject: Question regarding CaChannel -v1.6 compilation using python-3.2 onlinux 86-64 bit

Dear Sir,

I am trying to compile CaChannel v1.6 using python-3.2 on linux x86-64. The compilation  gives following error. Does CaChannel supports python3 ?

Seeking suggestions and comments

Best regards,
