OOB during package build

[iagobaapellaniz]

Building CUDArt fails. After solving the rest of problems I encountered in the way, I get this error now, which I cannot solve

LoadError: BoundsError: attempt to access 0-element Array{String,1} at index [1]
...

I'm not an expert on this, so I can give more details if you want, but I preferred to keep the thread as simple as possible.

Can you post the full backtrace?

The version info shows this

Julia Version 0.5.2

Platform Info:
  OS: Linux (x86_64-redhat-linux)

If I try to build CUDArt I obtain this.

julia> Pkg.build("CUDArt")
INFO: Building CUDAdrv

===============================[ ERROR: CUDArt ]================================

LoadError: BoundsError: attempt to access 0-element Array{String,1} at index [1]

================================[ BUILD ERRORS ]================================

WARNING: CUDArt had build errors.

 - packages with build errors remain installed in /home/iapellaniz/.julia/v0.5
 - build the package(s) and all dependencies with `Pkg.build("CUDArt")`
 - build a single package by running its `deps/build.jl` script

==============================================================================

Is this what you mean by full backtrace?

[maleadt]

The catch ex ... rethrow(ex) seems to ruin the backtrace -- anybody knows how come?

Anyway, try removing that and re-run build. That is, change CUDArt/deps/build.jl from:

try
    main()
catch ex
    # if anything goes wrong, wipe the existing ext.jl to prevent the package from loading
    rm(ext; force=true)
    rethrow(ex)
end

into

main()

and re-run Pkg.build. Now post the full back-trace.

Backtraces are much better on 0.6 so it would be worth checking there.

Going to close this for lack of information. Please run deps/build.jl manually, ie. julia CUDArt/deps/build.jl instead of Pkg.build("CUDArt") as Pkg truncates the stacktrace.

Also, the build system has changed a bit, so this just might be fixed already.

I wasn't able to perform a build to obtain the related info since I installed everything from scratch. I still have some problem but not related to this issue anymore. Thanks anyway.

I still have some problem but not related to this issue anymore.

If you do, just open another issue, or open a thread on Discourse. But please try and include a full backtrace + version/commit info, otherwise this kind of issue is really hard to debug.
