For anybody passing by here: for some reason I am still getting the error (MacOS 12.6, M1). Some success with the following change, which incidentally links against the VMD-supplied Tcl library.
VMDDIR="/Applications/VMD 1.9.4a57-arm64-Rev12.app/Contents/vmd"
PLUGINDIR=$(VMDDIR)/plugins/MACOSXARM64/tcl
FRAMEWORK=-F $(VMDDIR)/../Frameworks -framework Tcl
CPPFLAGS=-fpic -O3 -Wall ${TCLINC} -DVERSION=\"${VERSION}\"
qwrap.so: qwrap.o
$(CXX) -dynamiclib -DUSE_TCL_STUBS $< $(FRAMEWORK) -o $@

What is the error message?

I can't find this error message anywhere. Check that it is exactly the error that you get. Please copy and paste a larger block of output messages to give me more info.

I have the same issue on my mac:
c++ -fpic -O3 -Wall -ansi -pedantic -fno-for-scope -I/usr/include/tcl8.6 -DVERSION=\"1.4\" -c -o qwrap.o qwrap.cpp
clang: error: the clang compiler does not support '-fno-for-scope'
make: *** [qwrap.o] Error 1
Indeed, there is not much to go on when one tries to google this.
Obviously, without the -fno-for-scope all hell breaks loose.

Thanks @balazsfabian for this info. Can you change line 8 of the Makefile with this:
CPPFLAGS=-fpic -O3 -Wall ${TCLINC} -DVERSION=\"${VERSION}\"
and see if that helps?

Changing the CPPFLAGS resulted in
c++ -fpic -O3 -Wall -I/usr/include/tcl8.6 -DVERSION=\"1.4\" -c -o qwrap.o qwrap.cpp
llvm-g++ -shared qwrap.o -o qwrap.so -I/usr/lib64

Please try with the version of the Makefile I just pushed. Thanks.

Issue solved, the compiler is happy now (and so am I). Thanks a lot!

Hi @balazsfabian , would you mind testing this variant of the Makefile for me?
Makefile.test.gz
Here I'm not linking explicitly with Tcl, but suppressing the unresolved symbol errors from the linker. I'd rather not link explicitly with the system library if I can avoid it.

Thanks for testing. I find this behavior of the linker annoying, but I don't see a better workaround for now, so let's keep it as is.
