################################################################################ # Meson package infrastructure # # This file implements an infrastructure that eases development of # package .mk files for Meson packages. It should be used for all # packages that use Meson as their build system. # # See the Buildroot documentation for details on the usage of this # infrastructure # # In terms of implementation, this Meson infrastructure requires # the .mk file to only specify metadata information about the # package: name, version, download URL, etc. # # We still allow the package .mk file to override what the different # steps are doing, if needed. For example, if _BUILD_CMDS is # already defined, it is used as the list of commands to perform to # build the package, instead of the default Meson behaviour. The # package can also define some post operation hooks. # ################################################################################ # # Pass PYTHONNOUSERSITE environment variable when invoking Meson or Ninja, so # $(HOST_DIR)/bin/python3 will not look for Meson modules in # $HOME/.local/lib/python3.x/site-packages # MESON = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/meson NINJA = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/ninja NINJA_OPTS = $(if $(VERBOSE),-v) # https://mesonbuild.com/Reference-tables.html#cpu-families ifeq ($(BR2_arcle)$(BR2_arceb),y) PKG_MESON_TARGET_CPU_FAMILY = arc else ifeq ($(BR2_arm)$(BR2_armeb),y) PKG_MESON_TARGET_CPU_FAMILY = arm else ifeq ($(BR2_aarch64)$(BR2_aarch64_be),y) PKG_MESON_TARGET_CPU_FAMILY = aarch64 else ifeq ($(BR2_i386),y) PKG_MESON_TARGET_CPU_FAMILY = x86 else ifeq ($(BR2_m68k),y) PKG_MESON_TARGET_CPU_FAMILY = m68k else ifeq ($(BR2_microblazeel)$(BR2_microblazebe),y) PKG_MESON_TARGET_CPU_FAMILY = microblaze else ifeq ($(BR2_mips)$(BR2_mipsel),y) PKG_MESON_TARGET_CPU_FAMILY = mips else ifeq ($(BR2_mips64)$(BR2_mips64el),y) PKG_MESON_TARGET_CPU_FAMILY = mips64 else ifeq ($(BR2_powerpc),y) PKG_MESON_TARGET_CPU_FAMILY = ppc else ifeq ($(BR2_powerpc64)$(BR2_powerpc64le),y) PKG_MESON_TARGET_CPU_FAMILY = ppc64 else ifeq ($(BR2_riscv)$(BR2_RISCV_32),yy) PKG_MESON_TARGET_CPU_FAMILY = riscv32 else ifeq ($(BR2_riscv)$(BR2_RISCV_64),yy) PKG_MESON_TARGET_CPU_FAMILY = riscv64 else ifeq ($(BR2_s390x),y) PKG_MESON_TARGET_CPU_FAMILY = s390x else ifeq ($(BR2_sh4)$(BR2_sh4eb)$(BR2_sh4a)$(BR2_sh4aeb),y) PKG_MESON_TARGET_CPU_FAMILY = sh4 else ifeq ($(BR2_sparc),y) PKG_MESON_TARGET_CPU_FAMILY = sparc else ifeq ($(BR2_sparc64),y) PKG_MESON_TARGET_CPU_FAMILY = sparc64 else ifeq ($(BR2_x86_64),y) PKG_MESON_TARGET_CPU_FAMILY = x86_64 else PKG_MESON_TARGET_CPU_FAMILY = $(ARCH) endif # To avoid populating the cross-file with non existing compilers, # we tie them to /bin/false ifeq ($(BR2_INSTALL_LIBSTDCPP),y) PKG_MESON_TARGET_CXX = $(TARGET_CXX) else PKG_MESON_TARGET_CXX = /bin/false endif ifeq ($(BR2_TOOLCHAIN_HAS_FORTRAN),y) PKG_MESON_TARGET_FC = $(TARGET_FC) else PKG_MESON_TARGET_FC = /bin/false endif # Generates sed patterns for patching the cross-compilation.conf template, # since Flags might contain commas the arguments are passed indirectly by # variable name (stripped to deal with whitespaces). # Arguments are variable containing cflags, cxxflags, ldflags, fcflags define PKG_MESON_CROSSCONFIG_SED -e "s%@TARGET_CC@%$(TARGET_CC)%g" \ -e "s%@TARGET_CXX@%$(PKG_MESON_TARGET_CXX)%g" \ -e "s%@TARGET_AR@%$(TARGET_AR)%g" \ -e "s%@TARGET_FC@%$(PKG_MESON_TARGET_FC)%g" \ -e "s%@TARGET_STRIP@%$(TARGET_STRIP)%g" \ -e "s%@TARGET_ARCH@%$(PKG_MESON_TARGET_CPU_FAMILY)%g" \ -e "s%@TARGET_CPU@%$(GCC_TARGET_CPU)%g" \ -e "s%@TARGET_ENDIAN@%$(call qstrip,$(call LOWERCASE,$(BR2_ENDIAN)))%g" \ -e "s%@TARGET_FCFLAGS@%$(call make-sq-comma-list,$($(strip $(4))))%g" \ -e "s%@TARGET_CFLAGS@%$(call make-sq-comma-list,$($(strip $(1))))%g" \ -e "s%@TARGET_LDFLAGS@%$(call make-sq-comma-list,$($(strip $(3))))%g" \ -e "s%@TARGET_CXXFLAGS@%$(call make-sq-comma-list,$($(strip $(2))))%g" \ -e "s%@BR2_CMAKE@%$(BR2_CMAKE)%g" \ -e "s%@PKGCONF_HOST_BINARY@%$(HOST_DIR)/bin/pkgconf%g" \ -e "s%@HOST_DIR@%$(HOST_DIR)%g" \ -e "s%@STAGING_DIR@%$(STAGING_DIR)%g" \ -e "s%@STATIC@%$(if $(BR2_STATIC_LIBS),true,false)%g" \ $(TOPDIR)/support/misc/cross-compilation.conf.in endef ################################################################################ # inner-meson-package -- defines how the configuration, compilation and # installation of a Meson package should be done, implements a few hooks to # tune the build process and calls the generic package infrastructure to # generate the necessary make targets # # argument 1 is the lowercase package name # argument 2 is the uppercase package name, including a HOST_ prefix # for host packages # argument 3 is the uppercase package name, without the HOST_ prefix # for host packages # argument 4 is the type (target or host) ################################################################################ define inner-meson-package # # Configure step.
