REPAST HPC WSL Installation leads to boost no being found

Question

When trying to run Repast HPC executables I get the following error:

./main.exe: error while loading shared libraries: libboost_mpi-mt.so.1.61.0: cannot open shared object file: No such file or directory ./main.exe: error while loading shared libraries: libboost_mpi-mt.so.1.61.0: cannot open shared object

In the make file I define the link to boost in an env file with the below:

BOOST_INCLUDE= -I$(HOME)/sfw/Boost/Boost_1.61/include/
BOOST_LIB_DIR= -L$(HOME)/sfw/Boost/Boost_1.61/lib/

This is linked to a make file with the following make file

include ./env

.PHONY: clean
clean:
    rm -f *.o
    rm -f *.exe

.PHONY: compile
compile:
    $(MPICXX) $(BOOST_INCLUDE) -c Main.cpp -o Main.o
    $(MPICXX) $(BOOST_LIB_DIR) -o main.exe Main.o $(BOOST_LIBS)

.PHONY: all
all: clean compile

Boost in tsnow@DESKTOP-IF7CEHL:~/sfw/Boost/Boost_1.61/lib$ so it should link well across.

Any help appreciated, just trying to get a tutorial running.

We typically don't link repast to boost, but rather use rpath to let the model executable know where the boost and repast libraries are. For example in your Makefile:

REPAST_LIB_DIR = $(REPAST_HOME)/lib
BOOST_LIB_DIR = $(HOME)/theta/sfw/boost-1.66.0/lib
RPATHS += -Wl,-rpath -Wl,$(REPAST_LIB_DIR) -Wl,-rpath -Wl,$(BOOST_LIB_DIR)

and then add $(RPATHS) after the list of libraries during linking.

model : $(EXEC_OBJECTS)
    $(CXXLD) -fopenmp -dynamic $^ $(LIBS) $(RPATHS) -o $(NAME)

Some of those args might not be appropriate for WSL, but hopefully the RPATHS part makes sense.

So, if after your include directive, you add

RPATHS=-Wl,-rpath -Wl,$(BOOST_LIB_DIR)

and update the second line of your compile target with

$(MPICXX) $(BOOST_LIB_DIR) -o main.exe Main.o $(BOOST_LIBS) $(RPATHS)

The location of your boost libs is compiled into main.exe, and it should find it.
