iBCS package has support for running FreeBSD binaries under Linux; but it's old and unmaintained. I cannot get it to work. Please let me know if you have had better luck with this.
FreeBSD has the ability to run Linux binaries, both in a.out and ELF formats. To do this you have to take the following three steps:
/etc/rc.conffile and change
linux_enable="YES"and reboot. Another way to load the Linux binary support is to execute the command
/usr/bin/linux. This way you don't have to reboot, and you don't always have the Linux binary support loaded (i.e. you save memory.) Remember to add the line
options COMPAT_LINUXto the FreeBSD kernel config file if you build a new FreeBSD kernel.
linux_lib-2.4.tgz(newer versions might be available.) Run the following command to install the package:
pkg_add <path_to_package>/linux_lib-2.4.tgz<path_to_package> is the directory where the package is stored. You may also load it off the net by:
pkg_add ftp://ftp.freebsd.org/pub/FreeBSD/packages-stable/All/linux_lib-2.4.tgzor by re-running
/stand/sysinstall. Enter ``Configure'', ``Packages'' and use the menus. You should execute the following command if you are running statically linked Linux binaries:
brandelf -t Linux <name_of_statically_linked_linux_binary>
I have successfully run the Linux versions of Applixware 4.3 and Netscape 3.01 (both ELF format) under FreeBSD 2.2.2 using this method (yes, I know there is a native FreeBSD version of Netscape 4.) The Linux versions of acroread and StarOffice 3 and 4 also work well under FreeBSD. StarOffice 5 depends on native Linux threads and currently do not work under FreeBSD. Read the FreeBSD documentation for more information on this topic.
