Can you explain that? Good question. There isn't a solid explanation. heretofore, I have been using a lot of bash scripting in combination with awk sed and some perl. I was directed to look into python. My tasks were becoming increasingly complex and memory intensive. I started with a desire to connect to a mysql server. For that I needed to install the MySQLdb module. I am having difficultly in acomplishment of this task. I suppose for the time it has taken, using windows python would have been the simpler route. Oh. And all this time, I thought it was because you needed to run on a Linux server and were using Cygwin for debugging. I routinely develop Python on Windows and run on Linux servers. This works fine, provided that you can find versions of any necessary C modules for Python for both platforms. John Nagle -- http://mail.python.org/mailman/listinfo/python-list

Re: trouble installing MySQLdb (cygwin) + Bonus question
Nothing againest mysqlDB but I had tried using it sometimes and found it little difficult to use when you left the connections open idle for sometime . I had used PySQLPool then to solve my issues. Give it a try, I would recommend it.

trouble installing MySQLdb (cygwin) + Bonus question
Hi, I'm a python newbie. By newbie I mean two days ago. It was suggested to me that I work with python. Unfortunately at work I must run this on a windows machiene. However, I am having difficultly installing MySQLdb. First is it even possible under my current environment?
