Solution for Broken compilervars.sh with zsh (on MacOS 10.15.7) after latest compiler update.

[FDuncanH]

The most recent version of the shell script compilervars.sh added a section  to

remove duplicate paths.     Its fine for bash, but breaks zsh (whis no default in MacOS.

"echo $(!arg) "  is incorrect  syntax in  the zshell scripting.

 I found the fix below ,   It might be useful for anyone using zhell on macos.

Broken script

------------------function remove_duplicate_paths----------------------------

remove_duplicate_paths() {
local arg=$1

if [ "${INTEL_HOST_PLATFORM}" = "Darwin" ]; then
local arr=(`echo ${!arg} | sed 's/:/\'$'\n/g'`)
else
local arr=(`echo ${!arg} | sed 's/:/\n/g'`)
fi

fixed script below

# ------------------function remove_duplicate_paths----------------------------
remove_duplicate_paths() {
local arg=$1
eval "value=\"\${$arg}\""
if [ "${INTEL_HOST_PLATFORM}" = "Darwin" ]; then
local arr=(`echo ${value} | sed 's/:/\'$'\n/g'`)
else
local arr=(`echo ${!arg} | sed 's/:/\n/g'`)
fi

Thanks, I confirm this worked for me on 10.15.7 with zsh.  Now onto the next problems with updating macos+intel+openmpi...
