Executable format on Linux and FreeBSD
 

If I compiled a simple 'hello world' C program in FreeBSD, but linked it to glibc instead of FreeBSD's libc, would that be a valid Linux executable?

Im thinking it might work.. A quick google search shows the following:

Install the linux_devel package, then run /compat/linux/bin/sh. This
will do all the right things with regards to your search path, with *one*
exception.

If you run a GNU configure script (or similar), it will find the BSD
ranlib, and use that on your Linux libraries. You can circumvent this
by making an empty, executable `ranlib` file somewhere in the Linux
executable hierarchy (eg. /compat/linux/usr/bin).

Running the Linux-mode shell is fairly important; you can get by
without it for simple things, but for more complex stuff you really
want to have the right shell.




I guess ive never tried writing linux specific code on BSD b4 :p
