Hello, are anyone using CxxWrap.jl library? I am trying to figure out a way to pass array to the function. So far I have came up to to this nonworking (makes julia to crash) code #include <string> #include <cxx_wrap.hpp>
std::string greet(float * mem) { return "hello, world"; } JULIA_CPP_MODULE_BEGIN(registry) cxx_wrap::Module& hello = registry.create_module("Hello"); hello.method("greet", &greet); JULIA_CPP_MODULE_END which is compiled with makefile all: code JULIA_DIR = $(shell which julia) IJULIA = $(shell dirname $(shell dirname $(JULIA_DIR)))/include/julia ICxxWrap = $(shell julia -e 'print(Pkg.dir("CxxWrap","deps","usr","include"))') LDIR=$(shell julia -e 'print(Pkg.dir("CxxWrap","deps","usr","lib"))') LIBS = -lcxx_wrap -ljulia CFLAGS=-I$(IJULIA) -I$(ICxxWrap) -L$(LDIR) code: code.cpp g++ code.cpp -fPIC -std=c++11 -lcxx_wrap -shared -o libhello.so $(CFLAGS) and eventually interfaced with using CxxWrap wrap_modules(joinpath(".","libhello")) @show Hello.greet() My small project needs to interface one function which takes a structures. These stores pointers to arrays and other parameters which I would like to set up in julia. So I also need to understand understand how to set and get values from interfaced structs for example DoubleData from https://github.com/barche/CxxWrap.jl/blob/master/deps/src/examples/types.cpp.
