Re: [Modules] Issue around MANPATH in Modules 5.5.0

[Paul M. <pau...@gm...>]

Interesting.

It looks like you are installing from source (by the install location).

When I installed 5.5.0, I used the config options:  --disable-set-binpath --disable-set-manpath
Maybe you need to use: --disable-set-binpath


My copy (as installed) looks exactly like the below in that section (it is completely commented out).


    if {[getState shelltype] in {sh csh fish}} {
       # add Modules bin directory to PATH if enabled but do not increase ref
       # counter variable if already there
       ##nagelfar ignore #26 Strange command
       #if {{/stage/site/modules/5.5.0/bin} ni [split [get-env PATH] :]} {
          #prepend-path --ignore-refcount PATH {/stage/site/modules/5.5.0/bin}
       #}

       # add Modules man directory to MANPATH if enabled
       # initialize MANPATH if not set with a value that preserves manpath
       # system configuration even after addition of paths to this variable by
       # modulefiles
       #set manpath {}
       # use manpath tool if found at configure step, use MANPATH otherwise
       ##nagelfar ignore +2 Too long line
       ##nagelfar ignore Found constant
       #catch {set manpath [exec -ignorestderr 2>/dev/null manpath]}
       ##if {[isEnvVarDefined MANPATH]} {
       ##   set manpath $::env(MANPATH)
       ##}
       #if {{/stage/site/modules/5.5.0/share/man} ni [split $manpath :]} {
       #   if {![isEnvVarDefined MANPATH]} {
       #      append-path MANPATH {}
       #   # ensure no duplicate ':' is set
       #   } elseif {[envVarEquals MANPATH :]} {
       #      remove-path MANPATH {}
       #      append-path MANPATH {}
       #   }
       #   prepend-path MANPATH {/stage/site/modules/5.5.0/share/man}
       #}
    }
