It seems that this is actually a glibc problem and while 2.6.4 builds
without the patch on newer versions of gcc (@8:), it still sometimes
segfaults (as observed during the doxygen build).
Remove 2.6.3 as preferred version (but keep it available for
building). The latest version (currently 2.6.4) is now preferred
(according to Spack's defaults).
- 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
Fixes#8152
Flex 2.6.4 doesn't build with gcc@7:. This sets Flex 2.6.3 as the
preferred version. The flex package had a conflict directive for
this but originally the recorded conflict was specific to ubuntu;
this appears to be an issue on multiple operating systems so this
also updates the conflict to be more general and adds a comment
which links to the relevant issues.
- The buggy flex-2.6.2 was blacklisted in the corresponding flex
package, but now also removed the md5sum to avoid suggesting that
this version should be revived.
The 2.6.3 has similar problems (at least for scotch), but 2.6.4
seems to work.
- Rejig flex restriction for scotch to exclude 2.6.2-2.6.3 only. Since
flex-2.6.4 appears to be okay again, we can remove the flex version
restriction that trickled through into the openfoam packages as a
consequent of an spack spec bug.
- Make flex a build dependency for the openfoam packages
(seems to have been an earlier oversight).
* flex: create variant +lex that creates symlinks for lex and libl.{a,so}
* flex: enable variant +lex by default
* flex: use dso_suffix for portability; replace repetitive code with a loop
* AutotoolsPackage: added configure_directory to permit build out of source. The configure script executable is now invoked with an absolute path. Modified a few packages accordingly.
* build_systems: functions returning directories are now properties
* build_systems: fixed issues with tcl and tk
* AutotoolsPackage: reworked recipe for autoreconf
* Update flex package url's and versions
The old sourceforge page for flex is now defunct. While version 2.6.0
still downloads fine, later versions are no longer hosted there.
Development continues on github. I've adjusted urls to point to this
new location.
In addition, from 2.6.0 onwards, a new naming scheme for releases seems
to have been adopted. I've created a url_for_version function to sort
this out.
* Change flex to an AutotoolsPackage
Also move the url_for_version function to the end of the package
definition.
* Implement the autoreconf function for flex
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).
