ELF interpreter ld-linux.so.2 not found

ProcalX · 07-24-2008, 10:47 AM

I run FreeBSD 6 on a Intel QuadCore dedicated server, logged in as root I am trying to install a piece of game server software using: ./cod4_lnxded

However I recieve this error:

PHP Code:



ELF interpreter /lib/ld-linux.so.2 not found 
Abort trap

From doing a few google searches this suggests that I am missing some libraries and that I need to install a linux emulator port?

How do I do this please?

Thank You

Try this:

Code:

# kldload linux
# kldstat
(Should output something like this):
Id Refs Address    Size     Name
 1    2 0xc0100000 16bdb8   kernel
 7    1 0xc24db000 d000     linux.ko

If that works fine, you can then install the libraries via ports like such:

Code:

# cd /usr/ports/emulators/linux_base-fc4
# make install distclean

If you don't have ports installed, then you can add the libs manually (A much bigger headache, imho).

If you've got all of that going and it's still not working, then try this:

Code:

# ldd cod4_lnxded

That'll produce output similar to this:

Code:

libXt.so.3 (DLL Jump 3.1) => /usr/X11/lib/libXt.so.3.1.0
libX11.so.3 (DLL Jump 3.1) => /usr/X11/lib/libX11.so.3.1.0
libc.so.4 (DLL Jump 4.5pl26) => /lib/libc.so.4.6.29

You'll need to hunt down those files and ensure they're in /compat/linux and that you've got symlinks in place to point from what the binary you're trying to run is looking for (the first column) to the last column (that I highlighted). In the end for this example, you'd have something like this:

Code:

/compat/linux/usr/X11/lib/libXt.so.3.1.0
/compat/linux/usr/X11/lib/libXt.so.3 -> libXt.so.3.1.0
/compat/linux/usr/X11/lib/libX11.so.3.1.0
/compat/linux/usr/X11/lib/libX11.so.3 -> libX11.so.3.1.0
/compat/linux/lib/libc.so.4.6.29
/compat/linux/lib/libc.so.4 -> libc.so.4.6.29

Let me know if that info helps.

Edit - I found all of this info here: http://www.freebsd.org/doc/en_US.ISO...c-install.html

There's quite a bit more info there that may be of assistance.

Thank you for you response, when I type in: kldload linux I recieve this message:

PHP Code:



kldload: can't load linux: Operation not permitted

When I type: kldstat I get this message:

PHP Code:



ID REFS Address            Size    Name
1   2   0xffffffff80100000 a47150  kernel
2   1   0xffffffff80b48000 1408    accf_http.ko

When I try: ldd cod4_lnxded I get this:

PHP Code:



ldd: cod4_lnxded: can't read program header
ldd: cod4_lnxded: not a dynamic executable

With reference to the article on the freebsd.org site you linked to it states:

You will need the Linux shared libraries that the program depends on and the runtime linker

How do I know what the "program depends on" and what the correct runtime linker is?

You got this error as root, or as your normal user? You should su or sudo to root to run that.

This info you can get with the ldd command, but you need to have the linux.ko module loaded.

With some help from a kind soul on IRC i've got linux module etc sorted:

However when I run: ldd cod4_lnxded I get given this:

PHP Code:



ldd: cod4_lnxded: can't read program header
ldd: cod4_lnxded: not a dynamic executable

when I do: /usr/compat/linux/usr/bin/ldd cod4_lnxded it just goes straight to a new line no output.
