The version of LLVM used by flang is new enough that CppBackend doesn't exist. Unfortunately, `flang-xxxxxxxx` is seen as < `3.9.0` by the version check.
* add a special case for `flang` versions.
- We've seen this a few times now where users have set up `cd` to echo
the new directory, and it screws up `setup-env.sh`
- In the past we've said this is user error.
- Here, we just fix it by sending `cd` output to /dev/null where needed.
- this works in bash, zsh, and dash
Add an example of a 'modules:' entry for an external package in
packages.yaml. The 'External Packages' section of 'Build
Customization' mentions 'paths:' and 'modules:' and gives an
example of paths, but not modules.
* OpenFOAM: rationalize architecture options
- older versions of OpenFOAM had WM_ARCH_OPTION to choose a 32-bit
build on 64-bit architectures. This is not exactly relevant anymore
and has now been largely removed from OpenFOAM.
- simultaneously the newest version of OpenFOAM has rationalized the
handling of special settings for KNL by rolling these into the
compiler options. We now do the same thing here in spack.
1. Reuse the internal variable arch_option to convey processor-specific
optimizations and add these into the C++OPT=... statement.
2. Drop spack support for configuring a 32-bit build on 64-bit
hardware.
These changes can also be applied to older OpenFOAM versions, and to
various OpenFOAM forks without issue.
* update openfoam versions. New release 1906, patched 1812 version.
ncl does not build with newer versions of gdal (or rather proj). This
also needs a small change to gdal, otherwise we end up with both proj@5
and proj@6 in the spec.
* Remove individual font-* packages and add them as resources of the
font-util package
* Update font-util package to Autotools-based package, and call
autoreconf to regenerate the old configure script
* Add font-adobe-utopia-type1
* fmt: Add cxxstd variant, plus cmake/c++ patches
Spack supported versions of fmt default to C++11 for versions
less than 5, C++14 greater than 5, with fmt implementing
fallbacks to whatever compiler supports.
To give better ABI compatibility and use of newer standards, provide
a `cxxstd` variant defaulting to 11 with 98-17 options. Use cmake_args
to set CMAKE_CXX_STANDARD as appropriate, plus use of `FMT_USE_CPP11`
option for C++98 builds. Use `conflicts` to disable use of certain
standards in versions that don't support, or fail the build, with
those standards.
Add patches to unify use of `CMAKE_CXX_STANDARD` in 3.0 versions,
remove hard-coding of compiler flags in `fmt-config.cmake`, and
prevent use of C++11 features in 4.1.0 when in supported C++98
mode.
Default to not building documents as no dependency on Doxygen is
yet present, and they are not part of the "all" build.
* Use CMake to enforce C++ standard support
Fail configure step if fmt tries to build with a cxxstd variant
not supported by the compiler (or known to CMake).
* fmt: New version 5.3.0
