GLIBC version issues

[pfrater]

I just git cloned and compiled the most recent version of GADGET. It works great for the example here: ftp://ftp.hafro.is/pub/reiknid/dst2/gadget/haddock2.1.05.tar.gz

but when I call gadget on my older models I get the following errors.

gadget: /lib64/libm.so.6: version `GLIBC_2.23' not found (required by gadget)
gadget: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by gadget)
gadget: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by gadget)

Any idea what the issue is?

Thanks, Paul

My guess there is a mix up with different binaries of gadget, try doing which gadget in the different model directories and see if these yield different results

I don't think so. It happens even when I compile gadget in the directory (and don't add it to my path) then call model files using ./gadget -s. This is on a shared cluster (IHPC Garpur) running CentOS, so I'm not sure if there is a problem with the versions on the system there or not.

My guess is on the setup of the cluster, you may want to contact the administrator. Just to double check does the same issue occur on the mfdb machine?

That's the weird thing. I contacted the administrator initially before posting here. He replied saying that he could get a model to run with the following code:

module purge
module load gcc/6.1.0
git clone https://github.com/Hafro/gadget.git
cd gadget/
make
curl -O ftp://ftp.hafro.is/pub/reiknid/dst2/gadget/haddock2.1.05.tar.gz
tar -xvf haddock2.1.05.tar.gz
cd haddock
../gadget -s -i refinputfile 

I was able to replicate this on the garpur cluster and it worked fine, so not sure what the issue is. But when I try it with an older model that I set up (gulllax) I get the errors initially alluded to. I do not have this problem on mfdb server...everything runs fine there.

I'm guessing the issue is related to the module which is (or is not) loaded on the Garpur cluster, see http://www.hpc.cam.ac.uk/using-clusters/user-environment-and-modules . Looking at this one would assume that you need to make sure that the gcc module is available when running gadget.
