[Modules] Conflict with Tcl libraries in LD_LIBRARY_PATH

[Shaun D. v. lists.hpsf.i. <Sha...@li...>]

Hi All,

Module version :
Modules Release 5.5.0 (2024-11-11)
Platform :
Red Hat Enterprise Linux release 8.10 (Ootpa)

I have a vendor tool which provides its own shared object libraries including a copy of the Tcl libraries but doesn't provide a "tcl8.6" sub-directory that would contain 'init.tcl'
The module for the vendor tool needs the LD_LIBRARY_PATH environment to be adjusted to pick up its custom libraries

Unfortunately, if the tool library directories are prepended to LD_LIBRARY_PATH, this interferes with the Tcl that modules needs.

%> module load  tool-with-lib
%> module load  another-tool

ERROR: Can't find a usable init.tcl in the following directories:
      /vols/mmsimP4_t1b_008/ws/mmsimcm/mmsimcm_dep_0401/nsd_ext_lib/tcltk/tools.lnx86/tcltk-8.6.8/lib/tcl8.6 /usr/lib/tcl8.6 /lib/tcl8.6 /usr/library /library /tcl8.6.8/library /tcl8.6.8/library

  This probably means that Tcl wasn't installed properly.

      while executing
  "error $msg"
      (procedure "tclInit" line 61)
      invoked from within
  "tclInit"
      invoked from within
  "interp create $itrp"
      (procedure "execute-modulerc" line 60)
      invoked from within
  "execute-modulerc $dir/$elt $elt $elt"
      (procedure "getModules" line 101)
      invoked from within
  "getModules $dir $mod 0 [list rc_defs_included resolve]"
      (procedure "getPathToModule" line 49)
      invoked from within
  "getPathToModule $mod $modulepath_list $notfounderr"
      (procedure "cmdModuleLoad" line 30)
      invoked from within
  "cmdModuleLoad load 1 $tryload $loadany $tag_list {} {*}$args"
      (procedure "cmdModuleIntLoad" line 17)
      invoked from within
  "$cmdprocname {*}$cmdopts {*}$parsed_args"
      (procedure "module" line 186)
      invoked from within
  "{*}$execcmdlist"

What is the recommended/best way to get round this issue ?
I'm sure this issue has come up before, but I couldn't find answers on the internet.

Best regards
Shaun
