magicspp @2.29.4: error: ordered comparison between pointer and zero

[hbai24]

Hello,

I tried to install CDO with MacPorts, but failed. The error seemed to be with magicspp. This was my first time to install with MacPorts, and I did't have a clue what's wrong. My macOS is 10.12.6, Xcode version is 9.0.1, and MacPorts version is 2.4.2. Following is the error massage:

sudo port install cdo +grib_api +magicspp +szip
--->  Computing dependencies for cdo
The following dependencies will be installed: 
 cunit
 magicspp
 udunits2
Continue? [Y/n]: Y
--->  Building magicspp
Error: Failed to build magicspp: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_science_magicspp/magicspp/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port cdo failed

I also attached my log file. If you need any additional information, please let me know. Any reply is appreciated!! Thanks!

The inline comment (# exclude -Wl,-framework) in the magicspp Portfile cause the build to fail on my mac:

patchfiles          patch-CMakeLists.txt.diff \
                    patch-cmake-FindPangoCairo.cmake.diff # exclude -Wl,-framework

Removing it solved the issue.

The log says the problem was:

The misplaced comment was fixed in [a9e89f6e3ff706676fcffab721c605d902d2de9f/macports-ports].

This ticket is years old and the port has been updated several times since the ticket was filed, so I'll assume the original problem was fixed. If not, please file a new ticket with a new main.log from the latest version of the port.
