A programmer needs your help to get his program to compile properly on
freebsd. Presently he has no problems in Linux and winblows, but I could
not get it running in 4.11. This is important to me because it is the
strongest free chess program available and he is even giving the source!
and so can be made into a port some day. Here is my message and response
from him I am including the Makefile as an attachment:
Hi Eriq,
It refuses to link?
Ask BSD users and let me know what the solution is.

Make sure to add the appropriate include files but I don't think it would
have any effect.
>book.o(.text+0x83): undefined reference to `__errno_location'
#include <cerrno>
Maybe BSD has a problem with C++ notation
try replacing with the obsolete #include <errno.h>
>fen.o(.text+0x29e): undefined reference to `__strtol_internal'
Not sure with strtol (try man pages)
<cstdlib> or <cstring>?
>protocol.o(.text+0xd55): undefined reference to `stdin'
>protocol.o(.text+0xdb1): undefined reference to `stdout'
<cstdio>
>any help you can give me is great! I have a linux binary of fruit2.1

Well it looks like a linking issue specific to BSD to me.
Ask in appropriate forum and let me know their answer.
Fabien.
