Hello,
maybe it's the weather, maybe it's a side effect, but what happens here:
julia> Duktape._jl_duktape
"/home/lobi/juliarepo/duktape-0.11.0/src/duktape.so"
julia>
ccall((:duk_create_heap,"/home/lobi/juliarepo/duktape-0.11.0/src/duktape.so"),Ptr{Void},())
Ptr{Void} @0x0cfd5ee0
julia> ccall((:duk_create_heap,Duktape._jl_duktape),Ptr{Void},())
ERROR: type: anonymous: in ccall: first argument not a pointer or valid
constant expression, expected DataType, got Type{(Any...,)}
in anonymous at no file
i remember something about that the library needs to be found somehow, but
that would not explain the sucessful first call ... for me the difference
is just the string as literal or as variable.
