I have to install Twisted 2.50 on our Ubuntu Dapper servers. The problem is that I have to use the Twisted 2.50 tarball since Dapper apt repositories only have Twisted 2.40. The installation went smoothly and my twisted applications works except that when I try to run my scripts using the epoll reactor (twistd -ny ./myscript -r epoll) I get this error. (...)
When you built Twisted (through the setup.py script) it will build the epoll reactor if it can find the /usr/include/sys/epoll.h header file. So you might check if that is present on the system where you built Twisted. If not, you're probably missing some development packages. On my Ubuntu feisty system the file comes as part of the libc6-dev package. -- David
