Hi. I agree that this NCL page is confusing. <br>Simple solution<br>Go here: <a href="http://hpc.sourceforge.net/">http://hpc.sourceforge.net/</a><br>Download the gfortran binary for mac (it is best to follow very easy instructions before the link.)<br>
Then install NCL.<br>You are good to go. <br><br>Cheers,<br>Erik Noble<br>_______________________________________________________<br>Erik Noble<br>NASA Goddard Institute for Space Studies<br>2880 Broadway, New York, NY-10025, USA<br>

<div>Then, later it tells me to do this:</div><div><br></div><div><font face="'Courier New'"><span style="white-space:pre-wrap"> </span>fink install gfortran</font></div><div><br></div><div>Also, within the same section, it tells me that you got it from:</div>

<div><br></div><div>Also, later in the part close to the end, it says that the fortran version that the NCL binary is built against it should be installed.</div><div><br></div><div>I have installed ncl_ncarg-6.0.0.MacOS_10.6_64bit_gcc421.tar.gz, but it is not clear what version of gfortran is used (Is it the same as GCC version, which is 4.2.1?).</div>
<div><br></div><div>Also, when I installed Xcode 4.3.2, gcc and gfortran were installed already.</div><div><br></div><div>Also, fink install gfortran did not work, but this may be the one to use:</div><div><br></div><div>
<span style="white-space:pre-wrap"> </span><font face="'Courier New'">fink install gfortran-shlibs</font> [virtual library]</div><div><br></div><div>This installs gcc47-shlibs-4.7.0-100. Not sure what gfortran version it is, but I presume that gfortran is just a part of GCC and probably has the same version number???</div>
<div><br></div><div>By any rate, you also mentions that you have used gfortran from <a href="http://gcc.gnu.org/wiki/GFortranBinaries#MacOS" target="_blank">http://gcc.gnu.org/wiki/GFortranBinaries#MacOS</a>.</div><div><br>
</div><div>This provides only gfortran-4.6.2-x86_64-Lion.dmg for download.</div><div><br></div><div>This is the gfortran package installed last on this system.</div><div><br></div><div><div><div><div><font face="'Courier New'">$ gfortran --version</font></div>

<div><br></div><div>By the way, this page says it would require csh or tcsh, but Mac requires only bash.</div><div><br></div><div>Please correct it to include Mac OS X, or include the similar instruction (step-by-step of how to install and test/run) in the "Running NCL under MacOSX".</div>
<div><br></div><div><br></div><div>(5) Testing</div><div><br></div><div>After installing all these and setting below: (by the way default shell is bash, please correct this in your pages, too)</div><div><br></div><div><font face="'Courier New'"><span style="white-space:pre-wrap"> </span>export DYLD_LIBRARY_PATH=/usr/local/lib</font></div>
<div><br></div><div>I had to hunt for information on how to install the NCL binary and set up its environment as (4).</div><div><br></div><div>For how to test and use, there should be a link to: (or the same should be included on the Mac OS Note page)</div>
