After checking .bash_profile, I saw that there are additional paths:
export LD_LIBRARY_PATH=${ALLIANCE_TOP}/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=${ALLIANCE_TOP}/lib64:${LD_LIBRARY_PATH}

Running "source ~/.bash_profile" adds these additional entries on top of
"coriolisenv":
/home/rohdo/alliance/install/lib64:
/home/rohdo/alliance/install/lib:

The first of these entries points to directory "lib64" in alliance which
doesn't exist for me. The second is a copy of an entry from coriolisenv (so is
redundant).

No other missing or broken exist in .bash_profile, .bash_rc, or .profile.

Ok checked my coriolisenv against yours.
LD_LIBRARY_PATH is meant to have library paths from coriolis:
/home/$USER/coriolis-2.x/Linux.x86_64/Release.Shared/install/lib
and from alliance:
/home/$USER/alliance/install/lib

Again I re-created the schroot, re-compiled yosys, coriolis, and checked that
coriolisenv is correct. Installing alliance returns the -lMut error as before.


The only difference between luke's coriolisenv and mine, as that his coriolis
library path uses the name "lib":
/home/lkcl/coriolis-2.x/Linux.x86_64/Release.Shared/install/lib
where's mine has "lib64"
/home/rohdo/coriolis-2.x/Linux.x86_64/Release.Shared/install/lib64

The coriolis I installed uses the folder "lib64" so that's why there's a
difference ("lib" directory doesn't exist in my installation).

I do know of this shortcut as I normally use it, but in this script's case I
was following the existing nomenclature (also there are other commands that
require $USER anyway).

Thanks for the info!



Found no other missing/broken entries in coriolisenv.

Here's my coriolisenv (added newline chars for clarity):
