Error compiling WRF (GNU)

[siddhantsrivastava]

Hello,

I carefully followed this guide on installing the latest version of WRF and WPS on GNU architecture and I am getting an error when trying to compile. I am attaching my log.compile and configure.wrf files. I have already used the ./clean -a command and retried compiling but to no success. Any guidance will be appreciated.

Thanks!

Can you try compiling again (after clean and configure), but this time request only a single processor to compile:

./compile em_real -j 1 >& log.compile

and assuming it will still fail, then share the log.compile and the new configure.wrf file. Thanks!

Hello,

Thank you so much for looking into this. It did fail again with one processor. Attached is the new log.compile and configure.wrf files. For more context, I am trying to install this on a server running ubuntu.

Thanks!

This looks a lot like the issue found here:

Problem compiling WRF on Ubuntu, this: (AR="INTERNAL_BUILD_ERROR_SHOULD_NOT_NEED_AR") error presented.

Hello I am configuring and compiling WRF V4.4 for the first time, I am currently on Ubuntu 22.04.5, when I try to compile it, it does nothing and then it just mark error creating the executables. I've had previous errors with the netcdf path, I am guessing it has something to do with it. If...

which can be further confirmed by the output of mpif90 -show containing "lto" flags (e.g. -flto=auto)

It is worth noting, however that if it is the above case the reason for this happening is the MPI used in the configuration is using /usr/bin/mpif90 and not the mpif90 created from the setup instructions. This means it is using the default installed mpif90 of Ubuntu which is including flags which we do not support. A better solution when you've built using the guide instructions is to ensure you have the built binaries in your PATH.

The following excerpt from the linked guide (just after all the build+install instructions) is what adds the proper mpif90 that was user-built to the PATH:

export PATH=$NETCDF/bin:$DIR/mpich/bin:${PATH}

NETCDF and DIR must be set according to the previously noted instructions from the guide.

Thank you so much islas! The issue was related to the mpif90 issue and it was resolved using your answer from the linked post.
