installation ignores --environ

[kdd]

I tried to compile environ 3.1 together with QE7.1 following the installation instructions on GitHub. To me, it looked as if the installation had been successful - at least I got plenty of "environ" stuff during the compilation the the compile ends successfully. However, once I run pw.x --environ <pw.in in a directory in which a file environ.in is present, it seems to ignore the --environ flag and does not seem to search for the environ.in file (at least, I do not get the line "Reading input from environ.in:" in the output)

I am not quite sure where to look for the problem (in the compile, my input, ...) and help would be appreciated.

In the following part of the log file that I get when compiling QE with environ in the ./configure to show why I think the install goes all right:

And here the first few lines of my output:

I would have thought that there should come a statement "reading from environ.in" before the PPs.

Thank you in advance!
