Binaries may not expect shared libraries in /lib{,64} about singularity HOT 12 CLOSED

Ahh, good find! I think I have a very portable way of fixing this and will implement as soon as possible and let you know for testing.

Thanks!

from singularity.

I updated the ldd dependency resolver to use the default library paths and use LD_LIBRARY_PATH to update the search path. Will you recreate your SAPPs and let me know what you find?

Thank you!

from singularity.

Looks good!

from singularity.

I closed to early. When an application itself requires LD_LIBRARY_PATH set, the libraries are fetched into the sapp, but they are not found on execution. Am I missing something?

from singularity.

Ahhh, that is a good catch. Some variables should be caught and replicated into the SAPP. I'll think about how to do it and implement something when I get to the computer. Let me know if you think of a fix too!

Thanks!!

I just committed a method which will find all libraries in the SAPP and include them in the LD_LIBRARY_PATH. Can you check to see if that is working now? Thanks!

from singularity.

Hmm, no.
I compiled something with ICC, which needs
/opt/intel/composer_xe_2015.5.223/compiler/lib/intel64
to be in LD_LIBRARY_PATH.

What is your way to debug this?

from singularity.

Looking into ~/.sapp-cache/heat/c/singularity:
...
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/lib/x86_64-linux-gnu
/opt/intel/composer_xe_2015.5.223/compiler/lib/intel64"
...

Newline instead of colon?

from singularity.

Woops... Sorry about that! I just committed a fix that will work... Will test as soon as I get into work.

from singularity.

The fix seems to be working for me, but I don't have a use-case on this system with multiple libdirs. Can you confirm the latest commits are working better?

Thanks!

from singularity.

Works fine here.

from singularity.

Excellent, thanks!
