gethostbyaddr on Ubuntu 64

running the configure script for mozart oz gives me this:

checking for stdint.h... (cached) yes

checking for gethostbyaddr in -lnsl... no

checking for geth开发者_运维问答ostbyaddr in -lc... no

checking for gethostbyaddr... no

configure: error: Function gethostbyaddr is not available.

The system cannot be built.

how do I get gethostbyaddr on my latest ubuntu 64 machine?

do a

sudo apt-get install tk-dev tcl-dev build-essential libc6-dev g++-multilib ia32-libs lib32z1-dev lib32gmp3-dev

this fixes it.

gethostbyaddr is in the C library, which must be installed for a working Ubuntu system. There's probably a bug in the configure script.

I don't know why the configure script fails, but you may want to remove all lines referencing gethostbyaddr from mozart/platform/emulator/configure.in, followed by an autoreconf.
