Travis testing for Julia's C API

[Jake Bolewski]

I'm trying to set up an example Travis environment for testing python -> julia bindings.  When julia installs it seems like the built libjulia is not symlinked to /usr/lib/julia/ (but this could be an Arch / Ubuntu policy distinction).  Specifying the correct path allows ctypes to find the library but now it complains that it cannot find the system image file sys.jl.  I could play around with this some more but I'm hoping that someone can provide some clues about how to set this up correctly.

Best,

Jake

Hi Jake!

There are 2 problemas: jl_init() appends "../lib/julia" to the path parameter if you specify it, and for some reason, ubuntu installs julia under /usr/lib/x86_64-linux-gnu. The solution I found on my ubuntu was to use "/usr/bin" as path parameter to jl_init() and create a symbolic link from /usr/lib/julia to /usr/lib/x86_64-linux-gnu/julia.

I think the jl_init() should be fixed because it's just weird to append "../lib/julia" to the path.

That reason is multiarch. https://wiki.debian.org/Multiarch

Hi Patrick!

I didn't knew that. For that reason, we need get rid of this extra path append (../lib/julia), on jl_init(), because on ubuntu we'll have the binary and the .so in paths with different prefix.
