Unable to build Tahoe-LAFS v1.10.0 on FreeBSD 10

[manas]

Hello,

I am trying to set up Tahoe-LAFS v1.10.0 on FreeBSD 10 inside a jail. Please see the attached text file. In summary, an error seen is conftest.c:1:10: fatal error: 'sys/epoll.h' file not found among many others like unexpected token, unknown use of instruction mnemonic without a size suffix etc. Please see the text file for full details.

Thanks, Manas

This build failure on FreeBSD 10 would be fixed by ​https://tahoe-lafs.org/trac/pycryptopp/ticket/85

Replying to zooko:

Wait, how do we know that? "unknown use of instruction mnemonic without a size suffix" sounds as though it is from assembler code, but "'sys/epoll.h' file not found" doesn't.

[daira]

Oh, but the epoll error wasn't what caused the build to fail.

Do you have any workarounds to recommend so that I can run Tahoe-LAFS on FreeBSD 10?

[bawtA]

I'm also interested in a workaround so I can use Tahoe-LAFS on FreeBSD 10. If there is no workaround, will this be fixed in v1.11?

[daira]

This is a pycryptopp bug. The pycryptopp ticket (​https://tahoe-lafs.org/trac/pycryptopp/ticket/85) seems to have got stalled, I'm not sure why.

[cloud_trouble]

I found a workaround for this issue. You can run tahoe-lafs on FreeBSD using a Debian kFreeBSD jail. Just create a debian jail with debootstrap from ports/sysutils/debootstrap and then install tahoe-lafs using apt-get install tahoe-lafs.

Basic steps (on FreeBSD 10):

install debootstrap from sysutils/debootstrap mkdir /path/to/jail debootstrap jessie /path/to/jail kldload linprocfs (and others) mount -t linprocfs none /path/to/jail/proc (same for dev and sys) jail /path/to/jail jail_name jail_IP /etc/init.d/rc 2 jexec JID /bin/sh apt-get install tahoe-lafs create non-root user and configure tahoe-lafs.

Search for "FreeBSD Debian jail" for better details.

I got the email about the planned 1.10.1 release.

Will this issue be fixed in time for the release?

[daira]

The problem is actually with pycryptopp, so it's independent of the Tahoe-LAFS release (and a "quickstart" build will normally pick up the latest pycryptopp version). Nevertheless we should try to fix ​https://tahoe-lafs.org/trac/pycryptopp/ticket/85 soon.

[manas]

Bumping this so that it gets some attention.

[daira]

Thanks for the reminder. The current status is that the pull request ​https://github.com/tahoe-lafs/pycryptopp/pull/26 has review comments and needs more work.

[exarkun]

pycryptopp is no longer a dependency of Tahoe-LAFS.
