[ncl-install] problem about installing ncl on macos

[Hu, Zeyuan]

Hi Kevin,


The output are:

ls -l /usr/local/lib/libgfortran*

-rwxr-xr-x  1 root  wheel   2798988 May 19 17:04 /usr/local/lib/libgfortran.5.dylib

-rw-r--r--  1 root  wheel  11332840 May 19 17:04 /usr/local/lib/libgfortran.a

lrwxr-xr-x  1 root  wheel        19 May 19 17:04 /usr/local/lib/libgfortran.dylib -> libgfortran.5.dylib

-rwxr-xr-x  1 root  wheel       993 May 19 17:04 /usr/local/lib/libgfortran.la

-rw-r--r--  1 root  wheel       198 May 19 17:04 /usr/local/lib/libgfortran.spec


You are right. I have installed the gcc-7.3-bin.tar.gz, and I can open NCL now.


Thanks very much,

Zeyuan

Hi Zeyuan,

Could you please try running the following command and reply with the output:
ls -l /usr/local/lib/libgfortran*

I think GCC/Gfortran 8.1.0 includes the library file “libgfortran.5.dylib” instead of the “libgfortran.4.dylib” (from GCC/Gfortran 7.3.0) that this particular build of NCL was compiled with, which is causing the “library not loaded” error at run time.

If that is the case, you will likely need to install the gcc-7.3-bin.tar.gz tarball from this site: http://hpc.sourceforge.net/<https://urldefense.proofpoint.com/v2/url?u=http-3A__hpc.sourceforge.net_&d=DwMFaQ&c=WO-RGvefibhHBZq3fL85hQ&r=iwgEBM7WPx-PlOs7Uu5-hLG2UwuhKY6bHhTcCn7Zjm8&m=MITFRx441VpuKtWJugRZBNT0ziWgRkxkfP4rlrtubqI&s=WBXwIX2sPA21LJypyuBdBq5RgTMVWovm4HiLlQ8k-bQ&e=>

I hope this helps,
Kevin
