Error in building OCSSW binaries; SeaDAS 8.2.0 Build from Source Code

[reema_mathew]

I'm trying to build SeaDAS 8.2.0 from source code. All third party libraries are built successfully.

'build' directory is successfully created and command 'cmake ..' is also successfully executed.

While trying to build OCSSW binaries using the command 'make -j 20', I get the following output:

What might possibly be going wrong here? Is there any workaround?

(OS: Ubuntu 22.04
gcc/g++/gfortran: 11.3.0
cmake: 3.22.1)

Sorry for the delayed response. Do you still have the same problem?

[reema_mathew]

Yes. I still face the same issue.

[OB SeaDAS - dshea]

with gcc11 you need some newer updates to the code. I have built opt/src and ocssw_src on ubuntu22.04 by installing tag T2023.5

install_ocssw -t T2023.5 --src
cd $OCSSWROOT
rm -rf build
mkdir build
cd build
cmake ..
make -j 20 install

Your other option would be to install gcc-9, g++-9 and gfortran-9. If you change the compiler then you will need to rebuild opr/src and ocssw_src
