GROMACS version: 2024.1 GROMACS modification: Yes/No Hello, I am attempting to install gromacs 2024.1 patched with plumed 2.9 and apple silicon GPU support. It gets very close to finishing, but crashed out 90% into the gromacs make. It crashes out with the following error (amongst others): /downloads/gromacs-2024.1/src/gromacs/mdrun/md.cpp:308:118: error: use of undeclared identifier ‘ms’ 308 | simulationsShareState = useReplicaExchange || usingEnsembleRestraints || awhUsesMultiSim || (plumedswitch && ms); // PLUMED hack, if we have multiple sim and plumed we usually want them to be in sync Some details of the installation: - clang and clang++ are used to compile both plumed and gromacs (installed via home-brew) plumed is configured using ./configure --prefix=$MAIN\_INSTALL\_DIR --enable-modules=opes+crystallization+manyrestraints+pytorch gromacs is configured using cmake …/ -DCMAKE\_INSTALL\_PREFIX=$MAIN\_INSTALL\_DIR -DGMX\_GPU=OpenCL Any ideas would be really welcome. I have the same/similar issues when using gromacs 2023.2 as well as with the dev plumed 2.10 version. Thanks in advance! ---

Does GROMACS compile correctly without patching it with plumed? If so, it is a plumed related problem and you may have more luck and help in the plumed forum! ---

Hi obZehn, Yes it does so probably you are right! Thanks a lot :)
