I seems that FreeBSD 7.1 doesn't have strndup() function.

Hi, have you found a workaround for this? (ie implementing strndup yourself or compiling on FreeBSD 8.x, etc. etc.) Thanks!

Is it possbile to buil boost-jam on freebsd 7.1?

[anonymous]

edit tools/build/v2/engine/jam.c and replace (at 2 places)

strndup(buf, size)

by

strdup(buf)

At least you will be able to build j2 to then build boost.

This is boost.build's issue. And is FreeBSD 7 still supported?

The second use of strndup in jam.c is for linux case, I don't think it has to change, especially given that readlink documentation does not state that it will zero-terminate the string. I'd be happy to accept a pull request for FreeBSD 7, assuming it includes a comment explaining why on FreeBSD, the string will be zero-terminated and therefore using strdup is safe. I don't have access to FreeBSD to try this myself.
