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
This updates the Spack QT package to enable building qt version 4 on
MacOS.
This includes the following changes to the qt package:
* add version 4.8.7
* add option to build with or without shared libs
* add options to disable tools, ssl, sql, and freetype support
* add qt4-tools patch when building qt@4+tools
* add option to build as a framework (only available on MacOS)
* replace qt4-el-capitan patch with qt4-mac patch (which includes the
edits from qt4-el-capitan)
* apply qt4-pcre-include-conflict.patch only for version 4.8.6
(rather than all 4.x versions)
* apply qt4-gcc-and-webkit.patch for 4.x versions before 4.8.7 and
create a separate qt4-gcc-and-webkit-487.patch for version 4.8.7
* update patch function for qt@4 on MacOS to update configure
variables relevant to Spack (e.g. PREFIX)
* add option to build freetype with Spack, as a vendored dependency
of QT, or not at all (default is to build with Spack)
This includes the following edits outside of the qt package:
* Update MacOS version utility function to return all parts of the
Mac version (rather than just the first two)
* gettext package: implement "libs"
* python package: add gettext as a dependency
- 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
- It's not really a circular dependency -- git is a run dependency of gettext
- We can revert this change when Spack is smart enough to make git a run
dependency and build it.
