ncarg: checksum mismatch

[mike@…]

ncarg not avail on any macports site

subsequently downloaded ncarg zip file per instructions: fetch Download ncl_ncarg-6.0.0.tar.gz manually and place it in /opt/local/var/macports/distfiles/ncarg.

See instructions on ​http://www.ncl.ucar.edu//Download/index.shtml

reran sudo port install ncarg

failed due to checksum differences

Unable to reproduce. The checksums match for me. Try downloading the file again. Make sure you got the complete file. It should be 42919263 bytes.

I scp'd directly from NCAR's glade file system:

-rw-r--r-- 1 mpage staff 56770101 Aug 2 09:41 ncl_ncarg-6.0.0.MacOS_10.6_64bit_nodap_gcc421.tar.gz

/Users/mpage/desktop $ > cksum ncl_ncarg-6.0.0.MacOS_10.6_64bit_nodap_gcc421.tar.gz 2141362465 56770101 ncl_ncarg-6.0.0.MacOS_10.6_64bit_nodap_gcc421.tar.gz

but this is a binary file. The source file matches the size that you have specified. In ESG's new download procedure you can select from among two flavors of binaries or source.

I'll download the source file & try again.

Right, the message says to download ncl_ncarg-6.0.0.tar.gz, not ncl_ncarg-6.0.0.MacOS_10.6_64bit_nodap_gcc421.tar.gz.

I've just encountered this issue as well. It arose from strange behaviour of my Safari download from the EarthSystemGrid.

The file on that website (ncl_ncarg-6.1.2.tar.gz) renamed itself to ncl_ncarg-6.1.2.tar upon its download without actually untarring. Just appending the .gz suffix as I moved it to /opt/local/var/macports/distfiles/ncarg worked fine.

[tenomoto (Takeshi Enomoto)]

The .gz suffix refers to compressed with gzip. Just appending the suffix does not compress the tar archive. Even if the suffix is .tar.gz, it is still an uncompressed tar archive. To make Safari leave the downloaded file without uncompressing, uncheck open safe files after downloading in Safari's preferences.
