Re: [Modules] Conflict with Tcl libraries in LD_LIBRARY_PATH

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

Hi Xavier,

Thank you for the suggestion...
Unfortunately, this didn't work - I get the same error.

Just for additional info, the offending tool module does the following :

%> module display xcelium/test
-------------------------------------------------------------------
/sw/modules/modulefiles/cad/cdn/xcelium/test :

module-whatis   {Xcelium modules environment}
prereq          socionext
prepend-path    PATH $CADROOT/cdn/bin
prepend-path    PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/bin
prepend-path    PATH $CADROOT/cdn/org/xcelium/24.03.013/bin
prepend-path    LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/lib/64bit
prepend-path    LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/inca/lib/64bit
prepend-path    LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/lib
-------------------------------------------------------------------

Where $CADROOT is set to "/sw" in the "socionext" module.

Best regards
Shaun

Hi Shaun,

I suggest you to enable the quarantine mechanism and set LD_LIBRARY_PATH in the list of env variable to protect from.

In /etc/environment-modules/initrc, add the following lines:

  module config quarantine_support 1
  module config run_quarantine LD_LIBRARY_PATH

Then restart a new shell session.

It should protect the module execution from this interfering Tcl installation.

Best regards,
Xavier

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.

  "$cmdprocname {*}$cmdopts {*}$parsed_args"
      (procedure "module" line 186)
      invoked from within

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
