configure: error: failed to find required module pyftpdlib.servers

I'm using a qemu chroot environment configured according to http://code.google.com/p/picnc/wiki/QemuChrootCompiling I've read https://github.com/machinekit/machinekit/issues/317 carefully, and add none /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0 to the /etc/fstab according to @kinsamanka as saying, but I'm no lucky. Any hint will be helpful.

As the error says the package python-pyftplib is missing or not new enough. Do you have the package installed and in which version?

1.2 should be fine. Can your run python in your chroot environment and execute import pyftpdlib.servers

[xknot]

In the chroot:

mount /dev/shm

It works!

It seems like I met the problem described as: http://stackoverflow.com/questions/6033599/oserror-38-errno-38-with-multiprocessing

Is there any way not mount /dev/shm every time chroot? May be add something into the /etc/fstab of the host?

[zultron]

I use a script to start my chroots. It mounts /dev/shm and other stuff, too.

In use cases I've encountered, it wouldn't make sense to add chroot mounts to /etc/fstab unless there's only a single chroot in exactly the same place, and probably not even then.

[xknot]

Using a script is a good idea, thanks for your help.

I'll close it. Please reopen or submit new issue in case of further problems.
