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
Later versions of libjpeg-turbo build with CMake; to build with
user-specified cflags, the user must supply these to CMake as
-DCMAKE_C_FLAGS (Spack's typical approach of injecting these flags
into the compiler wrapper invocation is insufficient in this case).
Currently libjpeg-turbo cannot be implemented as a CMakePackage
(and thereby take advantage of the flag_handler implementation it
provides) because not all versions of libjpeg-turbo use CMake, so
this adds a custom implementation of flag_handler and
flags_to_build_system_args to libjpeg-turbo.
- 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
* Use libs[0] and headers.directories[0] instead of hardcoded paths in opencv dependencies
* Fix library finding in libjpeg-turbo
* Use build_type=Debug instead of +debug to determine build_type
Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
