<div dir="ltr">Hi Mary,<div><br></div><div>No, I haven't built from source yet. I'm going to try first with the standard packages I can get/have from MacPorts - it seems like everything is there, if you include the g2clib within GDAL. It also seems that GDAL made a major update back in September and not sure if any of your fixes/alterations to g2clib would've snuck in there or been fixed otherwise.</div><div><br></div><div>(text above written yesterday)</div><div><br></div><div>Build finished after I left work yesterday, successfully. Interestingly, the source tarball I downloaded seems to be quite old! It contains NCL 6.1.0-beta, a version that was outdated before I even purchased the computer. The executables are all dated 24 May 2012, which appears to be consistent with when such a build may have been released.</div><div><br></div><div>Regardless, I ran the example - gsun01n.ncl, and it immediately segfaults. I think this has to do with me not being able to easily get some of the X11 development libraries for Mac, which is more on me than anything. Changing the wks_type to png immediately allowed the script to run successfully. Other libraries I didn't/couldn't get via port include HDF-EOS5 and the patched g2clib. All other external software was included and built based only on the MacPorts versions available.</div><div><br></div><div>Still not sure how the source code contains 6.1.0-beta when downloaded from <a href="https://www.earthsystemgrid.org/dataset/ncl.630.2.html">https://www.earthsystemgrid.org/dataset/ncl.630.2.html</a> (I can confirm the file size matches the one listed for 6.3.0 source). But regardless, build from scratch seems to work well on 10.11 when the appropriate paths are provided in the Q&A section of the config.</div><div><br></div><div><br></div><div>Kyle</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">----------------------------------------<div>Kyle S.

While they can be set, this setting is not recognized in any automated (cron) calls to scripts. Here's on example output, where I print the contents of both environmental variables before attempting to run an NCL script. One environmental variable is set in .profile (manually sourced at start of the script) and one is set within the script itself. Both are ignored. </div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px"><p>/opt/local/lib/gcc49:/opt/local/lib/gcc</p><p>/opt/local/lib/gcc49:/opt/local/lib/gcc</p><p>dyld: Library not loaded: /usr/local/lib/libquadmath.0.dylib</p><p> Referenced from: /Users/ksgriffin2/ncl6.3.0.1010/bin/ncl</p><p> Reason: image not found</p></div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">The dyld:... error was originally missing libgfortran.3.dylib, but I manually created a link in /usr/local/lib to the version in /opt/local/lib/gcc49 try and tackle this problem. It appears that linking libgfortran.3.dylib, libquadmath.0.dylib, and libgomp.1.dylib does the trick to allow NCL to function as a workaround, but could be problematic long-term I would guess?
