Note: For the in-person event, a Fortran compiler supporting the entire Fortran 2008 standard is required; compilers with partial support are not supported. Therefore, it is not allowed to apply any patches located in patches/ nor modify src/common/signal.f90.
Sample build script:
Build json-fortran:
| Code Block |
|---|
git clone --depth=1 https://github.com/jacobwilliams/json-fortran.git
cd json-fortran && mkdir b && cd b
cmake -DCMAKE_INSTALL_PREFIX=/path/to/installation -DUSE_GNU_INSTALL_CONVENTION=ON ..
make install |
Build Neko:
| Code Block |
|---|
#!/bin/bash # Load Intel Compilers and MPI libraries. export MPIFC=mpif90mpiifort export CC=mpiccmpiicc export FC=$MPIFC export PKG_CONFIG_PATH=/path/to/jsonfortran/liblib64/pkgconfig:${PKG_CONFIG_PATH} ./regen.sh ./configure --prefix=<path> make make install |
Sample Sample run script:
| Code Block |

# Untar tgv.zip
cd tgv
# Load Intel Compilers and MPI libraries.
