I'm trying to create a solver in /OpenFOAM/applications/solvers/electromagnetics using

foamNewSource App newSolver

But, I keep getting the following error:

wmakeFilesAndOptions error: environment variable $WM_OPTIONS not set

I'm running EndeavourOS Linux x86_64 with kernel 5.15.6-arch2-1 and shell bash 5.1.12. In order to set up OpenFOAM (v9), I have the following in my .bashrc config file:

source /opt/OpenFOAM/OpenFOAM-9/etc/bashrc
PATH=$PATH:/opt/OpenFOAM

Now, when looking at the environment variables, I couldn't see WM_OPTIONS in my system. So, after googling a little bit, I added this to my .bashrc file:

source /opt/OpenFOAM/OpenFOAM-9/etc/bashrc
PATH=$PATH:/opt/OpenFOAM
export WM_OPTIONS=linux64GccDPOpt

And now, doing env | grep WM:

WM_COMPILER=Gcc
WM_PRECISION_OPTION=DP
WM_PROJECT_USER_DIR=/home/ariedinger/OpenFOAM/ariedinger-9
WM_MPLIB=SYSTEMOPENMPI
WM_OPTIONS=linux64GccDPOpt
WM_ARCH=linux64
WM_LABEL_SIZE=32
WM_PROJECT=OpenFOAM
WM_THIRD_PARTY_DIR=/opt/OpenFOAM/ThirdParty-9
WM_CC=gcc
WM_LABEL_OPTION=Int32
WM_CFLAGS=-m64 -fPIC
WM_LINK_LANGUAGE=c++
WM_OSTYPE=POSIX
WM_PROJECT_VERSION=9
WM_DIR=/opt/OpenFOAM/OpenFOAM-9/wmake
WM_ARCH_OPTION=64
WM_CXXFLAGS=-m64 -fPIC -std=c++0x
WM_PROJECT_INST_DIR=/opt/OpenFOAM
WM_LDFLAGS=-m64
WM_CXX=g++
WM_COMPILE_OPTION=Opt
WM_PROJECT_DIR=/opt/OpenFOAM/OpenFOAM-9
WM_COMPILER_TYPE=system
WM_COMPILER_LIB_ARCH=64

I can see the WM_OPTIONS environment variable set, but nonetheless I keep getting the same wmakeFilesAndOptions error.

I don't know what configuration I'm messing up, so I'd appreciate some help!

Thanks!
