Can you give your versioninfo()? And are you by any chance on 32bit?

Ubuntu 14.04 is quite old, not sure it provides libCLFFT at all. Can you run the following from the command line?

sudo apt-get install libclfft-dev

[AStupidBear]

@dfdx

E: Unable to locate package libclfft-dev

[AStupidBear]

Maybe I have to manually download the binary. It'll be better if this can be handled in the build process of this package.

[dfdx]

Can you please modify this block from deps/build.jl:

if is_linux()
    provides(AptGet, "libclfft-dev", libCLFFT)
    if Sys.ARCH == :x86_64
        uri = URI(baseurl * "Linux-x64.tar.gz")
        basedir = joinpath(@__DIR__, "clFFT-$(version)-Linux-x64")
        provides(
            Binaries, uri,
            libCLFFT, unpacked_dir = basedir,
            installed_libpath = joinpath(basedir, "bin"), os = :Linux
        )
    end
end

to looks like this:

if is_linux()
    # provides(AptGet, "libclfft-dev", libCLFFT)   -- commented out
    if Sys.ARCH == :x86_64
        uri = URI(baseurl * "Linux-x64.tar.gz")
        basedir = joinpath(@__DIR__, "clFFT-$(version)-Linux-x64")
        provides(
            Binaries, uri,
            libCLFFT, unpacked_dir = basedir,
            installed_libpath = joinpath(basedir, "bin"), os = :Linux
        )
    else
       error("Architecture $(Sys.ARCH) is not supported")
    end
end

and post the output?

[AStupidBear]

Is @__DIR__ a julia 0.5 macro?

[dfdx]

It's in Compat, so it should work fine on Julia 0.5. Please checkout master branch before testing or modifying anything.
