* replace filter_compilers after install with filter_compiler_wrappers
* update checksum for _current_ 7.5 version
* make +python conflict with ~shared
* prepend the architecture specific lib directory to the LD_LIBRARY_PATH
Signed-off-by: Ricardo Silva <ricardo.silva@epfl.ch>
* Adding NEURON package widely used in computational neuroscience community
* flake8 fixes
* Add rx3d variant
* Addressed review comments from Adam
* Addressed 2nd review comments
* Added check for +mpi on bg-q
* Filter spack compiler wrappers in NEURON scripts
Add gcc march=native flag to make front-end build robust
* Make develop as preferred version due to bug in long filename handlings in <= v7.4
* Avoid use of gcc in cross compiling environment
Use arch specific options on cray and bg-q arch
* Simplify cross compiling build:
- v7.5 added and no longer need develop as preferred version
- legacy cray related options removed
- cross compiling args reduced
- python arguments reduced as neuron finds proper libraries
* Simplify bg-q configurations
* Cleanup and unify arch options
* Make sure to add commonly available packages as dependency
* Arch path added to dependent_environment as nrniv needed at runtime
* Support for Power 8 architecture
* Fix python3 on OS X
* flake8 fix
* remove unnecessary conflcist directives
