What do you mean by "doesn't find those libraries" ? Note that you can't directly use ccall to call into C++ libraries unless they have an `extern "C"` interface. You could try using Cxx.jl if there's not easy way to create `extern "C"` entry points, but it's easier to start with plain C at

Yeah, you need to restart Julia to recompile. If you're in Juno, just co Ctrl+j then Ctrl+k, and then run your script (you can also use Ctrl+j then Ctrl+c to clear the console). I find this easier than restarting the REPL. On Friday, July 8, 2016 at 4:23:44 PM UTC-7, Yichao Yu wrote: > > On

Is there a recommended way to getting around that? The example above had a union of only two types, but in the actual code I'm working on there are a couple more. Would I have to copying the code over and over with just small changes to the type signature? I guess you could use a macro to

The string unification is already in julia-0.5. There are functions called String(), Int(), and Float64(). In some cases there are lowercase variants, and these often "do more" (e.g., `float` will parse a string and return an AbstractFloat). The uppercase versions are the minimalist

You should really double (if not triple) the time when estimating. This is a rule of thumb. The technologies keep moving, and it is hard to tell whether Julia1.0 milestone will include new features. Even when Julia1.0 comes out, there are still issues on ecosystem and the documentation.

It used to be that [[1,2],[3,4]] would try to concatenate the two vectors into [1,2,3,4], which was inconsistent with Vector{Int}[[1,2],[3,4]] (which returns a vector of vectors). That syntax was deprecated in v0.4.x, and in v0.5 now means the same thing (and the same as in any other language
