Difficulty installing SeaDAS 7.4 OCSSW packages on linux

[amsayer]

Hi all,

I've been trying to install SeaDAS 7.4 and OCSSW packages on a 64-bit linux machine here, and have run into a problem. I got the files and am going through the instructions here: https://seadas.gsfc.nasa.gov/downloads/

I have successfully installed SeaDAS 7.4 using the "SeaDAS Visualization Installers" instructions on that page, into a directory /data3/asayer/seadas-7.4, and added the path to my login shell. (Note the install location for SeaDAS isn't in my home directory here due to a space limitation.)

I then went on to try to install the ocssw packages (I want source code and SeaWiFS). I did steps 1, 2, and 3 on the above link (checking for software, download the installer script, make install_ocssw.py executable). However when I try to run it I get an error message. My understanding is that for the source code and SeaWiFS processing packages, I should invoke the command as follows:

./install_ocssw.py --install-dir=/data3/asayer/seadas-7.4/ocssw --git-branch=v7.4 --src --seawifs

However doing so gives this output:

Do you know where I might be going wrong? I guess "error: unknown switch `B'" is the culprit but am not sure why/how to fix.

Cheers,

Andy

Also, since it is probably relevant, my OS is CentOS 6.9. And these are my installed software versions:

- git version 1.7.1
- curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.27.1 zlib/1.2.3 libidn/1.18 libssh2/1.4.2
- GNU bash, version 4.1.2(2)-release (x86_64-redhat-linux-gnu)
- Python 2.6.6

I've seen this before.   Check your version of git against the requirements.  Here, man git-checkout (for versions 2.11.0 or 2.16.2) has:
git checkout [-q] [-f] [-m] [[-b|-B|--orphan] <new_branch>] [<start_point>]

Thanks; I am not sure if we can update to a newer git here on this OS but can ask the sysadmin. What are the required versions? The page for requirements listed in the install instructions gives an error code: https://seadas.gsfc.nasa.gov/requirements.html

[amsayer]

It turns out that replacing -B with -b in install_ocssw.py was sufficient to get it to run and install without any error messages. :)

Good news.  The requirements page loads fine for me (here in Canada) at 7:30PM Eastern time.

The link should be:
https://seadas.gsfc.nasa.gov/requirements/

Seems the .html extension was erroneously left on that link when we migrated the web server content management a while back.
We'll get it fixed soon.

That link is fixed now.
