We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
* esmf: add patch when building with intel for 7.0.x
* esmf: set Makefile variables required to propagate CXX/F90 flags
* ncl: add ymake patch for @6.4.0:
* ncl: add pixman, bzip2, freetype dependencies
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 the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
Replace use of `shutil.copytree` with `copy_tree` and `install_tree` functions in `llnl.util.filesystem`.
- `copy_tree` copies without setting permissions. It should be used to copy files around in the build directory.
- `install_tree` copies files and sets permissions. It should be used to copy files into the installation directory.
- `install` and `copy` are analogous single-file functions.
- add more extensive tests for these functions
- update packages to use these functions.
* ncl: Fix temp directory
Currently, ncl is configured using a transient temp directory. This
leads to warnings such as this when executing ncl later on:
warning:"/tmp/ncl_ncar_xxxxxx" tmp dir does not exist or is not writable:
NCL functionality may be limited -- check TMPDIR environment variable
As this also breaks some functionality, use the system temp directory
instead (typically /tmp).
* ncl: Depend on esmf
esmf is required for some ncl scripts (such as ESMF_regridding.ncl).
Fixes a problem in ymake-filter: The line buffer is currently hardcoded to be
2048 bytes large but some Makefiles contain lines longer than that. This
caused the Makefiles to sometimes not be generated, consequently failing parts
of the build.
* ncl: add depends_on statements for bison, flex and libiconv
* ncl: depends on flex for building and linking
* ncl: links with -ll, so requires flex with variant '+lex'
* ncl: depends on szip; external hdf5 may not provide it
