G++ how to compile for FreeBSD on linux server

Question

I wrote some code for linux/unix(ld_preload), how can i compile it for FreeBSD on my Ubuntu Server using G++, or maybe other compiler?

Thanks!

@H2CO3: If the machines are the same arch, you don't even need that. FreeBSD tries very hard to have binary compatibility with Linux. — Linuxios, Jul 12 '12 at 15:16

No need to recompile: there's a shim for the differences that's a little more tightly integrated than just a compat library. Some linux-only facilities you'll need to avoid, and you do need to 'brand' the linux binaries w/ brandelf, your starting point is that link.

+1 for you instead of the ugly VM solution. Much more elegant. – Jul 12 '12 at 15:21

My recommendation would be to create a FreeBSD virtual machine (using software like virtualbox) and compile the code on that.

+1: avoids a leap of faith in the cross-compile environment or compat library – Robᵩ Jul 12 '12 at 15:16
