Code exits with 'rapidxml::parse_error'

[vyaas]

Hi,
I was able to get the code to compile successfully with the minimalist settings.
I'm trying to get the packaged tutorial case "MethaneCoflowFlame" to work for a CH4 global mechanism. At the first time step, the code exits with the following error:

Any idea about what this is due to? I am using the latest version of rapidxml and gcc on OpenFOAM-6.

Thanks!

Hi vyaas,

I have exactly same problem. Solvers successfully compiled but having this 'rapidxml::parse_error' during running the tutorials. I was wondering if this error has been solved yet. Thanks a lot!

I am using rapidxml-1.13 and OpenFOAM-6.

Best,
Bin

By default, on debian 11.6 (gcc-10.2.1, openmpi-4.1.0) I had the same issue.
I had to install a new toolchain (gcc-4.9.2+openmpi-3.1.6+libeigen-3.3.7+libboost-1.69+rapidxml-1.13) to make it work without runtime errors.
