Compilation error with gdxrrw package on Linux

[lolow]

An error occurs during the compilation of the gdxrrw package on Linux. This issue may be due to stricter rules enforced by the compiler.

rgdx.c: In function ‘checkRgdxList’:
rgdx.c:174:13: error: format not a string literal and no format arguments [-Werror=format-security]
  174 |       error(fieldErrorMsg);

cc1: some warnings being treated as errors

To resolve this, a few modifications can be made to the package. Please refer to the changes in the rgdx.c file at GAMS-dev/gdxrrw@master...lolow:gdxrrw:master

thanks for the hint!

Note that gdxrrw is not supported anymore by GAMS. They recommend to move to GAMS TRANSFERT, using the new package: https://github.com/GAMS-dev/transfer-r
I haven't tested it yet and I am not sure if it possible to do a smooth transition in our packages.

We are currently in the process of replacing gdxrrw with gamstransfer, but it is unfortunately not that easy as the output formats of both packages are quite different.
