ncarg: implicit declaration of function

[lucalelli]

Trying to install NCL on a Catalina, Xcode 12.0.1, CLT beta 12 Macports updated recently 2.6.2 -> 2.6.3 Installed ports upgraded.

Both options fail.

Opt 1) ncarg fails to build with

:info:build ./Keywords.h:30:10: fatal error: 'parser.h' file not found
:info:build wrapit.y:5:10: fatal error: 'ncarg/ncl/defs.h' file not found

Opt 2) Precompiled binaries from ​https://www.ncl.ucar.edu/Download/install_from_binary.shtml

fail at runtime with

dyld: Symbol not found: __ZdaPvm
  Referenced from: /Users/luca/Downloads/ncl/bin/ncl
  Expected in: /usr/lib/libstdc++.6.dylib

I could also use the second option but the

install_name_tool -change /usr/lib/libstdc++.6.dylib /opt/local/lib/gcc10/libstdc++.6.dylib /Users/luca/Downloads/ncl/bin/ncl

does not solve the issue either.

[ryandesign (Ryan Carsten Schmidt)]

There are lots of implicit declaration of function errors in the log*. This is a new problem in Xcode 12. It used to just be a warning. We should work with the developers of ncarg to fix this. Until we do, you can avoid the problem by downgrading to Xcode 11 and the Xcode 11 version of the command line tools.

Downgrading to Xcode and CLT 11.5 ncarg builds and runs.

The only thing is that it segfaults when working on files. I don't know if it is relevant to macports or to ncl only.

Beside that, ncl opens its shell and ncl_filedump dumps correctly.
