Hi
I am trying to build a gentoo based base system on 5.2-CURRENT, since
the few linux boxes we have to run are gentoo based and I like to keep
things the same...
Anyway, i am running into a problem. They have a bootstrap.sh step
that rebuilds gcc and glibc and a bunch of stuff after you install
their stage1.
I get this error:
CPP='gcc -E -x c-header'

The problem is that on a real linux system you can "execute"
ld-linux.so.2 but that does not work on FreeBSD compatibility. If you
execute it directly on a linux system (I have tried a gentoo and
mandrake system) you get this:
bash-2.05b# /lib/ld-linux.so.2
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
You have invoked `ld.so', the helper program for shared library
executables.
This program usually lives in the file `/lib/ld.so', and special
directives
in executable files using ELF shared libraries tell the system's program
loader to load the helper program from this file. This helper program
loads
the shared libraries needed by the program executable, prepares the
program
to run, and runs it. You may invoke this helper program directly from
the
command line to load and run an ELF executable file; this is like
executing
that file itself, but always uses this helper program from the file you
specified, instead of the helper program file specified in the
executable
file you run. This is mostly of use for maintainers to test new
versions
of this helper program; chances are you did not intend to run this
program.
--list list all dependencies and how they are resolved
--verify verify that given object really is a
dynamically linked
object we can handle
--library-path PATH use given PATH instead of content of the
environment
variable LD_LIBRARY_PATH
--inhibit-rpath LIST ignore RUNPATH and RPATH information in object
names
in LIST
bash-2.05b#
Anyone know how to get around this in setting up a linux base system on
FreeBSD using linux compatibility? I do have COMPAT_LINUX and a few
other things in my FreeBSD kernel.
Thanks
Chad
