Since gtkmm@3 at least requires it, to workaround a possible new bug in Meson.
Keep Meson at 0.60, because it also introduces useful features, such as
validating that the build options used exist.
* gnu/packages/build-tools.scm (meson-0.59): New variable.
Meson goes to lengths at preventing installation to directories outside of the
main installation prefix. This isn't convenient or desirable in Guix; patch
it out using a patch maintained by Nix.
* gnu/packages/patches/meson-allow-dirs-outside-of-prefix.patch: Add patch.
* gnu/local.mk (dist_patch_DATA): Register it.
* gnu/packages/build-tools.scm (meson): Use it.
Fixes <https://issues.guix.gnu.org/48552>.
* gnu/packages/build-tools.scm (meson): Update to 0.59.0, which includes a
reproduceability fix for builds that link against multiple LLVM libraries.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* gnu/packages/build-tools.scm (gn)[native-inputs]: Change from PYTHON-2 to
PYTHON-WRAPPER.
[arguments]: Remove trailing #t's and make some cosmetic changes.
The meson-for-build package doesn't carry any special patch anymore; it
appears to be obsolete.
* gnu/packages/build-tools.scm (meson-for-build): Remove variable.
* guix/build-system/meson.scm (default-meson): Use meson.
* doc/guix.texi (Build Systems): Update doc.
* gnu/packages/build-tools.scm (tup): New variable.
* gnu/packages/patches/tup-unbundle-dependencies.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register new file.
