Build error on OS X about nemo.jl HOT 7 CLOSED

Did you (try to) install it using Pkg.add or Pkg.clone("...Nemocas/Nemo.jl")?

from nemo.jl.

It looks like tar failed to open the pari archive.

Could you confirm that your machine is able to open the following archive
using tar:

http://pari.math.u-bordeaux.fr/pub/pari/unix/pari-2.7.4.tar.gz

@thofma I used Pkg.add("Hecke"). This pulled in Nemo as dependency.

@wbhart Yes, this works:

This won't work. To install Hecke you cannot use Pkg.add("Hecke"), but you have to do the following (see https://github.com/thofma/Hecke.jl):

julia> Pkg.clone("https://github.com/nemocas/Nemo.jl")
julia> Pkg.clone("https://github.com/thofma/Hecke.jl")
julia> Pkg.build("Hecke")

The problem is simple: Since we did not manage to update the official Nemo package, it still points to the old repository at https://github.com/wbhart/Nemo.jl/, which does not work anymore.

We'll be switching the repositories and issuing a new release within a week
or two at most.

Bill.

I think I found the problem.

• first, the code in deps/build.jl checks whether the directory pari-2.7.4 exists
• if not, the tarball is downloaded
• next, the tarball is untarred
• then the tarball is deleted

It is easy to come up with a scenario where the directory pari-2.7.4 exists, but the tarball does not exist. In this case, the tarball will not be downloaded, and will then be expanded by tar. That, of course, fails.

from nemo.jl.

I think the problem is that the pari homepage is occasionally down.
