* Disable parallel builds
The install step creates a bunch of links to the vim binary, e.g.
`view`. When run with -j greater than 1 there are silent failures.
Running w/out parallelism seems to fix it.
* Only constrain the install phase to be -j 1
Thanks @adamjstewart!
* add various variants to vim
* default to --enable-fail-if-missing
* vim package: -{python,ruby,lua,perl} sets build option to `no`
* vim's interpreter build options are `--enable-XXXXinterp={yes,no,dynamic}`
* dynamic seems to work only on windows builds
* `=no` is the default => use it in spack if the variant is disabled
* Update digest for vim@8.0 tarball.
The digest appears to have changed.
The new digest value matches the value in their
[MD5SUMS](ftp://ftp.vim.org/pub/vim/unix/MD5SUMS)
file.
* Change ftp.vim.org -> github.com/vim/vim/archive
Vim seems to do weekly releases, but the name of the tarball on
ftp.vim.org doesn't change so we have to regularly play 'update the
digest' (aka Internet whack-a-mole).
This commit changes the url so that we are now downloading particular
versions from the Vim project's github archive.
I didn't walk back through of time to get all of the versions that
used to be explicit. I grabbed the final `7.4` and the current `8.0`
releases. If people need more we can add them.
Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
