Not working on cross setups

[tgurr]

0.9 didn't work for me either. ldd lists the dependencies just fine:

But elflibviewer doesn't list anything:

[sergey-shambir]

Ok, 2 years ago there was issues with Debian/Ubuntu multiarch - ElgLibViewer was unable to find any lbiraries. I'd improved search algorithm, but it still isn't ideal. Can you please clarify on which system search failed? (which distribution, which version, i686 or AMD64).

[tgurr]

The distribution is Exherbo Linux, which is a rolling release distribution so we don't have any specific release versions, I'm on AMD64/x86_64.

We moved from multilib to multiarch/cross which allows native cross compiling support with full support from the package manager to track installed packages in the various cross targets.

Everything arch specific is installed to /usr/arch e.g. /usr/x86_64-pc-linux-gnu/{bin,include,lib,libexec}, /usr/i686-pc-linux-gnu/{bin,include,lib,libexec} and so on.

ls -la /usr:

bin -> host/bin
host -> x86_64-pc-linux-gnu
include -> host/include
lib -> host/lib
libexec -> host/libexec
sbin -> host/sbin

ls -la /:

bin -> usr/host/bin
lib -> usr/host/lib
sbin -> usr/host/sbin

so by changing the /usr/host symlink you can switch the whole system on the fly between the various installed cross targets.

More detailed information can be found here:
https://exherbo.org/docs/multiarch-pr.html
https://exherbo.org/docs/multiarch.txt

I hope this information is of any help and I was able to explain our layout, if I can be of further assistance please let me know.

[sergey-shambir]

Can you please also attach content of /etc/ld.so.conf and all files in /etc/ld.so.conf.d?

[tgurr]

We have /etc/env.d/ instead of /etc/ld.so.conf.d:

-rw-r--r--  1 root root  176 Sep  7 11:06 00basic

And running # eclectic env update then (re-)generates /etc/ld.so.{cache,conf}. The package manager also runs that command when instaling/removing any package so that it is always up to date:

# ld.so.conf autogenerated by eclectic
# Make all changes to /etc/env.d files
