This commit provides three minor improvements:
1. Fix missing proj support. Fixes#91889.
2. Fix missing libxml2 support.
3. Improve build time with parallel build.
Fix missing proj support:
-------------------------
The 2019-07-09 update to proj version 6.1.1 in nixpkgs
commit d55cba68ff caused two problems for mapnik:
1. The separation of the dev output was not reflected in the mapnik
expression. Since proj support is optional in the mapnik build,
the build succeeded but no longer included proj support.
See build log for: https://hydra.nixos.org/build/96274475.
2. Even if the mapnik expression was updated to use the separate
dev output, it would still have dropped proj support because mapnik
has not been updated for the proj 6 API.
This commit fixes the PROJ_INCLUDES to use the correct dev output and
also makes the PROJ_LIBS output explicit. In addition, it defines
ACCEPT_USE_OF_DEPRECATED_PROJ_API_H=1 since mapnik still does not have
a tagged release that supports the proj 6 api.
Looking to the future, it appears that the mapnik master branch includes
proj 6 support, so some checks were included to help insure that this
workaround gets removed once it is no longer required.
Fix missing libxml2 support:
----------------------------
Configure with "XMLPARSER=libxml2" to get libxml2 support. This has been
needed since mapnik 3.0.2. Remove XML2_INCLUDES and XML2_LIBS which
trigger a bug in the supplied SConstruct script (when used with
"XMLPARSER=libxml2.
In addition, libxml2 needs to be a propagatedBuildInput to avoid
errors building apacheHttpdPackages.mod_tile, python-mapnik, and
possibly other packages.
Enable parallel build:
----------------------
Setting enableParallelBuild does not result in a parallel build
with mapnik. However, setting JOBS=$(NIX_BUILD_CORES) in buildFlags
works and significantly reduces the build time.
The default config.in template contains
"include @sysconfdir@/sway/config.d/*" but we've dropped it to better
support non-NixOS (which seems like a mistake in retrospect).
This restores that behaviour and extends the default configuration via
nixos.conf to fix#119445.
Note: The security configurations (security.d) where dropped entirely
(but maybe they'll return).
- Drop compiler and stdver arguments – if someone needs to provide them, they can just use overrideAttrs
- Update repo source
- Narrow scope of `with lib` declaration
- Change optional → optionals
- Use one input per line
- Build on all unix platforms
- Re-order attributes
Due to improper sandboxing, I didn't notice the failed tests while
upgrading jupytext in #121648. The errors come from jupyter_core so
the same fix is used here as there: set $HOME to a writable directory.
This PR adds a new aarch64 android toolchain, which leverages the
existing crossSystem infrastructure and LLVM builders to generate a
working toolchain with minimal prebuilt components.
The only thing that is prebuilt is the bionic libc. This is because it
is practically impossible to compile bionic outside of an AOSP tree. I
tried and failed, braver souls may prevail. For now I just grab the
relevant binaries from https://android.googlesource.com/.
I also grab the msm kernel sources from there to generate headers. I've
included a minor patch to the existing kernel-headers derivation in
order to expose an internal function.
Everything else, from binutils up, is using stock code. Many thanks to
@Ericson2314 for his help on this, and for building such a powerful
system in the first place!
One motivation for this is to be able to build a toolchain which will
work on an aarch64 linux machine. To my knowledge, there is no existing
toolchain for an aarch64-linux builder and an aarch64-android target.
