Dear all,
Recently I have upgraded my mac book air to the macOS Catalina version
10.15.3 and since this version only supports 64-bit architecture
applications, I can no longer use available pre-compiled binaries of VMD
1.9.3 for my macOS.
I read the compilation guide for plugins in the below link:
but I have a problem with these two commands:

setenv TCLINC -I/Projects/vmd/vmd/lib/tcl/include
setenv TCLLIB -F/Projects/vmd/vmd/lib/tcl

first, the setenv command is not available on my system and also I do not
know which path these two lines refer to?

I also try to compile VMD plugins without running the above commands in the
plugins directory with the following command:
sudo gmake MACOSXX86_64
and I get these error messages:

gmake[2]: ../ Operation not permitted

gmake[2]: *** [Makefile:717: libmolfile_plugin.h] Error 127

gmake[2]: Leaving directory

gmake[1]: *** [Makefile:155: molfilelibs] Error 1

gmake[1]: Leaving directory '/Users/neda/Documents/Softwares/vmd/plugins'

gmake: *** [Make-arch:473: MACOSXX86_64] Error 2

Could you please help me with this?

Best Regards
