I'm in the process of wrapping part of an important tool for Radio
Astronomers: CasaCore (relevant branch:
https://github.com/mweastwood/CasaCore.jl/tree/maketraviswork).
Unfortunately CasaCore is a C++ library, so I have first written a C
interface that needs to be compiled.
I am using BinDeps to download and compile CasaCore (if it is not already
present on the system), and then build the C wrapper. On my own machine,
this works perfectly (although I am cheating somewhat because CasaCore is
already built on my machine):

However, on Travis, I'm at my wits end trying to figure out why this
doesn't work. See the build log here (note, scroll right to the bottom,
CasaCore is a huge dependency that takes a while to compile):
https://travis-ci.org/mweastwood/CasaCore.jl/builds/43496822
Confusingly, both CasaCore and my C wrapper seem to build successfully.
Indeed, checking the deps/usr/lib directory on Travis indicates that all
the appropriate shared libraries exist, but BinDeps fails with
Provider BinDeps.BuildProcess failed to satisfy dependency
libcasacorewrapper
while loading /home/travis/.julia/v0.4/CasaCore/deps/build.jl, in
expression starting on line 61
I would really appreciate any guidance on how to solve this problem.
