It's a very simple concept. If you have 64-bit FreeBSD dynamic linked binaries, you need the 64-bit FreeBSD shared libraries to run them. If you have 32-bit FreeBSD dynamic linked binaries, then you need the 32-bit FreeBSD shared libraries to run them. If you have the 32-bit linux dynamic binaries, then you need to have the 32-bit linux shared libraries. I have 314 libraries and symlinks in /usr/lib32. > So I guess some people have done this with the two copies you mentioned? David was talking about *building* the 32-bit software on a 64-bit machine. This isn't supported. What you can do is take a 32-bit binary, built on a 32-bit machine, and run it on your 64-bit amd64 system. "make buildworld" is setup to build the needed 32-bit libraries and loader on a 64-bit system/ > Then why if these 32 bit programs can't easily be built, if at all, do > we add such things as with_lib32=yes to make.conf and options like > LINPROCFS, COMPAT_LINUX32 ,COMPAT_IA32 , COMPAT_FREEBSD4 ,COMPAT_43 to > the kernel config? > I thought with these added in 32 bit program support was available?
