Description Alex 2018-09-09 16:17:01 UTC
Description of problem: Julia is missing a dependency to preform fft's. 


Version-Release number of selected component (if applicable): 0.6.3


How reproducible: Easily


Steps to Reproduce:
1. Run julia from shell
2. In julia's REPL run fft(rand(10))

Actual results:
 julia> fft(rand(10)) ERROR: error compiling Type: error compiling _init_: could not load library "libfftw3f_threads" libfftw3f_threads.so: cannot open shared object file: No such file or directory Stacktrace: [1] #plan_fft#5(::UInt32, ::Float64, ::Function, ::Array{Complex{Float64},1}, ::UnitRange{Int64}) at ./fft/FFTW.jl:596 [2] fft(::Array{Complex{Float64},1}, ::UnitRange{Int64}) at ./dft.jl:57 [3] fft(::Array{Float64,1}) at ./dft.jl:204 [4] macro expansion at ./REPL.jl:97 [inlined] [5] (::Base.REPL.##1#2{Base.REPL.REPLBackend})() at ./event.jl:73

Expected results:
julia> fft(rand(10))
10-element Array{Complex{Float64},1}:

Additional info:

The solution was to install fftw from @System repo in Fedora 28. So fftw needs to be a dependency of julia for fft to work.

Comment 3 Milan Bouchet-Valat 2018-09-09 17:57:24 UTC
Good catch. There are two versions of FFTW, and fftwf was missing from the dependencies. I've pushed a new version which should fix this.
