From ccc9e05990a44d8db5825c07ed61d405ebb40caa Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Mon, 25 Feb 2019 22:11:46 +0100 Subject: [PATCH] package/meson: install cross-compilation.conf during toolchain install package/meson installs a cross-compilation.conf file in $(HOST_DIR)/etc/meson, via TARGET_FINALIZE_HOOKS. package/pkg-cmake.mk installs a toolchainfile.cmake in $(HOST_DIR)/share/buildroot, via TOOLCHAIN_POST_INSTALL_STAGING_HOOKS. Both files have a similar concept, they describe some flags/paths needed for compilation using respective build systems. One difference is that the meson file is added for external compilation, from the SDK, while the cmake file is used internally in Buildroot. The 'problem' of using TARGET_FINALIZE_HOOKS for the meson file, is that it installs a 'host' file from target-finalize, which is conceptually incorrect since not just TARGET_DIR but also HOST_DIR is "regenerated" on a subsequent 'make' when everything was already built (i.e. only target-finalize is run). This can easily be fixed, by using the same hook as cmake uses, i.e. TOOLCHAIN_POST_INSTALL_STAGING_HOOKS. Note that actually even for cmake, TOOLCHAIN_POST_INSTALL_STAGING_HOOKS is not the best hook to install a host file. A better hook would have been TOOLCHAIN_POST_INSTALL_HOOKS, but this triggers only for 'host' packages, and 'toolchain' is treated as a 'target' package. Also, the hook (and therefore also the definition of PKG_MESON_INSTALL_CROSS_CONF) is moved to pkg-meson.mk, again to make it more similar to how it's done for cmake. Otherwise check-package complains that the meson package is setting variables that don't start with MESON_.
