* Update flex package url's and versions
The old sourceforge page for flex is now defunct. While version 2.6.0
still downloads fine, later versions are no longer hosted there.
Development continues on github. I've adjusted urls to point to this
new location.
In addition, from 2.6.0 onwards, a new naming scheme for releases seems
to have been adopted. I've created a url_for_version function to sort
this out.
* Change flex to an AutotoolsPackage
Also move the url_for_version function to the end of the package
definition.
* Implement the autoreconf function for flex
Adds the IceT compositing library from Sandia/Kitware.
Most default functionality needed for image compositing is
added, OpenGL acceleration for very large displays is disabled.
Downstream usage:
most VTK based software which supports parallel image compositing,
such as VisIt, Paraview and in our use-case
[ISAAC](https://github.com/ComputationalRadiationPhysics/isaac).
* Force the recipe for Lua to use the spack compiler.
I'm not sure how the old recipe worked for anyone. The Lua Makefiles set
`CC=gcc` and for my spack environment the first `gcc` found in my `PATH` is
`$SPACK_ROOT/lib/spack/env/gcc`, which is a directory. This caused the build
to fail. My change drops the `-std=gnu99`, but this option doesn't appear
to be required for a sucessful build.
* Preserve the '-std=gnu99' compile option.
* fix tau installation issue : setup_environment() is
called before install phase when 'Makefile.*' doesn't
exist (causing list index out of range error).
* Added detailed comment suggested by @alalazo
* November 1 seems to have brought a new texlive release, updating the
digest to match.
Also switching the url from their automagic mirror to an explicit
site to avoid inconsistencies during their updates.
It seems like only yesterday (#2073) that I updated this....
* Add comment to url warning about mirror updates
Add a comment to the download info warning to use a
specific site rather than the mirror, to avoid wobbles
during their asynchronous updates.
* Fix typo ('to no' -> 'do not')
On MacOS, brew installs /usr/local/bin/python but the Python prefix is not /usr/local/bin
Use the python command sys.exec to get the correct directory, instead of the ad hoc self.prefix
previously used
This was a bear to debug; been driving me nuts since I started using spack.
Since spack passes PYTHONHOME down to package builds in the environment
it was passing PYTHONHOME of /usr/local/bin to the PETSc build that uses Python so
the PETSc Python ./configure errored immediately with
ImportError: No module named site
since python could find no python modules. Todd Gamblin pointed out that my first try to fix
this was wrong since it assumed the spack python was the same python used to run spack. Elizabeth Fischer
suggested how to get it to work also with python3
