[MITgcm-support] Reading errors

[Martin Losch]

Hi Estanis,

this looks like a convoluted problem. We would need more information about the problem:
what is the platform, the compiler?
details of the configuration (content of code-directory and namelist files)
are you using latest code (some of the flags in the build-option look very outdated …)?

Your error message (attempt to access non-existent record) usually means that you are reading beyond the end of the file (i.e. not enough data in the file)

Not finding an input file usually does not have anything to do with the compiler setting, especially not the WORDLENGTH.

It turns out that the model cannot find the bin file. After doing some research in the mailbox of mitgcm. I found out that is due to the compiler settings. As it was advice, I set -DWORDLENGTH=1. Now, I am having a different error (error 2).
