I am compiling Julia program as dll and trying to call from another program.
The Julia program is as follows (I am planning to use commented out pkg):
module pjname
# using Statistics
# using CSV
# using DataFrames
# using DSP
# # using Plots
# using Dates
# using FindPeaks1D
Base.@ccallable function function_name(slen::Cint)::Cint
println(1)
return 0
end
end # module
The program I am using to compile the code is:
using PackageCompiler
PackageCompiler.create_sysimage(; sysimage_path="./src/prog_dl.dll", script="./src/prog.jl")
and the program I call the dll is as follows:
using Libdl
libmg = dlopen("H:/julia/pjname3/src/prog_dl.dll")
function_name = dlsym(libmg, :func_name)
ccall(function_name, Cint, (Cint,), Int32(1))
I get the following error. Could someone help me to figure out this issue? I tried Julia version 1.6.5 and 1.7.0 but both of them didn't work. I am using windows and VS Code as IDE.
Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.
