Maybe you are using an old WIEN2k version, the "x: Command not found" happened a lot in an older WIEN2k version.

To have the least problems with IRelast, you may want to consider upgrading to latest WIEN2k (currently, 21.1) using Intel oneAPI for the compiler.  If you use WIEN2k 21.1 with the gfortran compiler, you will likely need the calLa_Pre_elast.patch [1].


If you are having to use an old WIEN2k version.  Some old maybe inaccurate notes of mine that may or may not help are:


In the WIEN2k 19.2 directory of SRC_IRelast/script-elastic, must: chmod +x *

Also in $WIENROOT must: chmod +x initIR_lapw

The SRC_IRelast/script-elastic/initIR_lapw must be renamed or moved so that it does not override the one in $WIENROOT.

I have tried earlier given solutions (below) but cant remove error.

 1. chmod +x *
2.
 3. "Please move (not copy) initIR_lapw from
    SRC_IRelast/script-elastic to WIEN2k
    directory and then run it again."
 4. giving path in initIR_lapw

Kindly help.
