+ I am unable to build suite-sparse@5.2.0 with clang@6.0.0. The build fails
with the error:
```
2397 [ 99%] Linking C executable wildtype_demo
2398 make[4]: Leaving directory
`/tmp/kellyt/spack-stage/spack-stage-w0XYhK/SuiteSparse/GraphBLAS/build'
>> 2399 libgraphblas.so.2.0.1: undefined reference to `__fpclassify'
>> 2400 clang-6.0: error: linker command failed with exit code 1 (use -v to
see invocation)
>> 2401 make[4]: *** [wildtype_demo] Error 1
```
+ This error appears because libgraphblas.so requires `-lm`, but that link
dependency is not explicitly listed in GraphBLAS\CMakeLists.txt.
+ A patch file is provided to add this dependency. The patch is only applied
when the compiler is `%clang`.
* ADIOS 1.13.1
ADIOS 1.13.1 fixes several issues with zero-sized block
reading and writing when compression transports are used.
* SZ 1.4.12.3
Add the lastest SZ release used in ADIOS1.
* geopm: Added initial files for package geopm
and py-natsort dependency
* geopm: Updated variants for hwloc and mpi defaults
* geopm: Cleaned up unwanted hyphenation in description.
* geopm: updates according to change request.
* geopm: Updated minor change requests.
Clarification for ruby-ronn dependency included as a TODO.
This requires changes in the current configure and build process
which will be changed in a future version.
* geopm: changed to AutotoolsPackage and fixed hwloc
The changes for hwloc required to add a specific version bc of a
conflicting version of openmpi's hwloc dependency being below
1.99. This works but updates to this package should check if this
restriction is still required. (Thus TODO added)
* geopm: Added link dependencies (thanks for pointing this out).
Also removed empty line below class definition.
* geopm: Fixed depends_on according to package guide.
Removed wrong type 'run' and removed types for numactl, mpi and hwloc
to use default build & link type.
* geopm: Fixed and updated +doc dependencies
new pacakge ruby-ronn (package specified as in ruby-narray package)
Updated second +doc dependency doxygen.
* geopm: Changed args for Autotools specific feature.
Added enable_or_disable and with_or_without instead of if cascade.
Added overhead variant.
Also added missing dependency (default: build&link) for json-c).
* glvis@3.3: new package
* mesa-glu: now provides 'glu' (GL Utility library)
* openglu: add package, provides glu
* [GLVis] Use MakefilePackage as base. Add 'develop' version.
Small tweaks in the makefile arguments.
* [GLVis] Locate the X11, GL and GLU libraries within their respective
prefixes. Set the C compiler in the makefile arguments.
* [GLVis] Fix a bug: the same variable was used for two different things.
* [libx11] Add the libs property
* [OpenGL] Add the libs property
* [OpenGLU] Add the libs property
* [GLVis] Use the libs properties of libx11, opengl, and openglu
Activating a package that is already activated now sends a `tty.msg`
and returns.
```
-bash-4.2$ ~/spack/bin/spack activate aspell6-en
==> Package aspell6-en/lc4v24f is already activated.
```
* Better error message for spack providers
fixes#1355
`spack providers` now outputs a sensible error message if non-virtual
specs are provided as arguments:
```
$ spack providers mpi zlib petsc
==> Error: non-virtual specs cannot be part of the query [zlib, petsc]
```
Formatting of the output changed slightly.
* Calling 'spack providers' without arguments print the virtual pkg list
Also, the error message in case of a wrong parameter has been improved
to show the list of valid packages.
* Avoid printing headers if stdout is not a tty
* The provider list is formatted with colify if not in a tty
* Added a test to check the list of providers returned from the command
