Running `spack module refresh -m lmod --delete-tree -y` throws the
following warning:
```console
==> Warning: Could not write module file [/Users/oxberry1/spack/share/spack/lmod/darwin-sierra-x86_64/openblas/0.2.20-ibhtl5q/clang/5.0.1/ipopt/3.12.9.lua]
==> Warning: --> global name 'prefix' is not defined <--
```
This warning arises because the variable expansions in
`spack.modules.BaseFileWriter` occur at module/package scope. Even
though `prefix` is an argument to `install` methods in e.g.,
`MakefilePackage`, so using this argument within package methods is
legal, doing so defeats the introspection logic in
`spack.modules.BaseFileWriter`. Replacing `prefix` with `self.prefix`
resolves the problem, because the introspection logic in
`spack.modules.BaseFileWriter` can use introspection to query IPOPT's
prefix.
This makes use of the new flag_handler logic from 28d8784a to set
compiler flags for ipopt by passing them as arguments to the build
system rather than injecting them into the compiler wrappers. This
avoids conflicts between flags that are chosen by the build system
and flags that are set by the user.
Added line in package.py to patch using ipopt_ppc_build.patch. The patch simply adds support in config.guess and Ipopt/config.guess to build ipopt on ppc64le.
- Added a new interface for Specs to pass build information
- Calls forwarded from Spec to Package are now explicit
- Added descriptor within Spec to manage forwarding
- Added state in Spec to maintain query information
- Modified a few packages (the one involved in spack install pexsi) to showcase changes
- This uses an object wrapper to `spec` to implement the `libs` sub-calls.
- wrapper is returned from `__getitem__` only if spec is concrete
- allows packagers to access build information easily
Add package for the nonlinear programming solver IPOPT. This
commit depends on the changes made in GitHub PR #711, since IPOPT
requires the headers that correspond to the fake MPI implementation
in sequential MUMPS.
