Hey Kwesi,

thanks again for your advice. It still ran into the same problem when I
softlinked the library in /ncl_6.3.0/lib/. With some additional testing I
found out the following:
NCL only started when I put export DYLD_FALLBACK_LIBRARY_PATH=/
usr/local/Cellar/gcc/6.3.0_1/lib/gcc/6 into my .bashrc file. Removing this
line I received the same error as when I try to run the test script ng4ex
gsun01n -clean so I assumed that the problem was with the libstdc++.6.dylib
library in my /usr/lib/ folder. Originally it was only a softlink to
the libstdc++.6.0.9.dylib
library in the same folder. Since NCL was able to start when I put the
export DYLD_FALLBACK_LIBRARY_PATH line into my .bashrc-file, but ng4ex
produced the error, it is obvious that the ng4ex bin does not use the
library specified in the .bashrc file, but rather the default on in
/usr/lib/. So for now I got it to run by disabling the mac System Integrity
Protection (SIP) and replacing the libstdc++.6.dylib softlink with the full
library in usr/local/Cellar/gcc/6.3.0_1/lib/gcc/6/, which is a homebrew gcc
version I installed. Now it works perfectly, also ncl does start without
the export DYLD_FALLBACK_LIBRARY_PATH line in my .bashrc-file.
However, this can't be an optimal solution, since I don't know which
programs accessed the softlink in /usr/lib/ and can't get redirected
to libstdc++.6.0.9.dylib
anymore because i deleted the softlink. The real solution should be that I
can tell ng4ex and ncl and all the other bins in the ncl environment that
they have to access the library I specify in my .bashrc-file. Does anybody
know if that's possible? From my testing I conclude that the .bashrc file
only tells the NCL bin what to do.

Thanks to all for your help!

Kindly go into this folder rather;

cd /usr/local/ncl_6.3.0/lib

sudo ln -s /location/given/by/locating/libstdc++.6.dylib .

 Also remember to exit your terminal and re-enter your terminal before
starting ncl

Hope it helps. Cheer!!
