1################################################################################ 2# Meson package infrastructure 3# 4# This file implements an infrastructure that eases development of 5# package .mk files for Meson packages. It should be used for all 6# packages that use Meson as their build system. 7# 8# See the Buildroot documentation for details on the usage of this 9# infrastructure 10# 11# In terms of implementation, this Meson infrastructure requires 12# the .mk file to only specify metadata information about the 13# package: name, version, download URL, etc. 14# 15# We still allow the package .mk file to override what the different 16# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is 17# already defined, it is used as the list of commands to perform to 18# build the package, instead of the default Meson behaviour. The 19# package can also define some post operation hooks. 20# 21################################################################################ 22 23# 24# Pass PYTHONNOUSERSITE environment variable when invoking Meson or Ninja, so 25# $(HOST_DIR)/bin/python3 will not look for Meson modules in 26# $HOME/.local/lib/python3.x/site-packages 27# 28MESON = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/meson 29NINJA = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/ninja 30NINJA_OPTS = $(if $(VERBOSE),-v) 31 32# https://mesonbuild.com/Reference-tables.html#cpu-families 33ifeq ($(BR2_arcle)$(BR2_arceb),y) 34PKG_MESON_TARGET_CPU_FAMILY = arc 35else ifeq ($(BR2_arm)$(BR2_armeb),y) 36PKG_MESON_TARGET_CPU_FAMILY = arm 37else ifeq ($(BR2_aarch64)$(BR2_aarch64_be),y) 38PKG_MESON_TARGET_CPU_FAMILY = aarch64 39else ifeq ($(BR2_i386),y) 40PKG_MESON_TARGET_CPU_FAMILY = x86 41else ifeq ($(BR2_m68k),y) 42PKG_MESON_TARGET_CPU_FAMILY = m68k 43else ifeq ($(BR2_microblazeel)$(BR2_microblazebe),y) 44PKG_MESON_TARGET_CPU_FAMILY = microblaze 45else ifeq ($(BR2_mips)$(BR2_mipsel),y) 46PKG_MESON_TARGET_CPU_FAMILY = mips 47else ifeq ($(BR2_mips64)$(BR2_mips64el),y) 48PKG_MESON_TARGET_CPU_FAMILY = mips64 49else ifeq ($(BR2_powerpc),y) 50PKG_MESON_TARGET_CPU_FAMILY = ppc 51else ifeq ($(BR2_powerpc64)$(BR2_powerpc64le),y) 52PKG_MESON_TARGET_CPU_FAMILY = ppc64 53else ifeq ($(BR2_riscv)$(BR2_RISCV_32),yy) 54PKG_MESON_TARGET_CPU_FAMILY = riscv32 55else ifeq ($(BR2_riscv)$(BR2_RISCV_64),yy) 56PKG_MESON_TARGET_CPU_FAMILY = riscv64 57else ifeq ($(BR2_s390x),y) 58PKG_MESON_TARGET_CPU_FAMILY = s390x 59else ifeq ($(BR2_sh4)$(BR2_sh4eb)$(BR2_sh4a)$(BR2_sh4aeb),y) 60PKG_MESON_TARGET_CPU_FAMILY = sh4 61else ifeq ($(BR2_sparc),y) 62PKG_MESON_TARGET_CPU_FAMILY = sparc 63else ifeq ($(BR2_sparc64),y) 64PKG_MESON_TARGET_CPU_FAMILY = sparc64 65else ifeq ($(BR2_x86_64),y) 66PKG_MESON_TARGET_CPU_FAMILY = x86_64 67else 68PKG_MESON_TARGET_CPU_FAMILY = $(ARCH) 69endif 70 71# To avoid populating the cross-file with non existing compilers, 72# we tie them to /bin/false 73ifeq ($(BR2_INSTALL_LIBSTDCPP),y) 74PKG_MESON_TARGET_CXX = $(TARGET_CXX) 75else 76PKG_MESON_TARGET_CXX = /bin/false 77endif 78 79ifeq ($(BR2_TOOLCHAIN_HAS_FORTRAN),y) 80PKG_MESON_TARGET_FC = $(TARGET_FC) 81else 82PKG_MESON_TARGET_FC = /bin/false 83endif 84 85# Generates sed patterns for patching the cross-compilation.conf template, 86# since Flags might contain commas the arguments are passed indirectly by 87# variable name (stripped to deal with whitespaces). 88# Arguments are variable containing cflags, cxxflags, ldflags, fcflags 89define PKG_MESON_CROSSCONFIG_SED_COMMON 90 -e "s%@TARGET_FC@%$(PKG_MESON_TARGET_FC)%g" \ 91 -e "s%@TARGET_ARCH@%$(PKG_MESON_TARGET_CPU_FAMILY)%g" \ 92 -e "s%@TARGET_CPU@%$(GCC_TARGET_CPU)%g" \ 93 -e "s%@TARGET_ENDIAN@%$(call qstrip,$(call LOWERCASE,$(BR2_ENDIAN)))%g" \ 94 -e "s%@TARGET_FCFLAGS@%$(call make-sq-comma-list,$($(strip $(4))))%g" \ 95 -e "s%@TARGET_CFLAGS@%$(call make-sq-comma-list,$($(strip $(1))))%g" \ 96 -e "s%@TARGET_LDFLAGS@%$(call make-sq-comma-list,$($(strip $(3))))%g" \ 97 -e "s%@TARGET_CXXFLAGS@%$(call make-sq-comma-list,$($(strip $(2))))%g" \ 98 -e "s%@BR2_CMAKE@%$(BR2_CMAKE)%g" \ 99 -e "s%@PKGCONF_HOST_BINARY@%$(HOST_DIR)/bin/pkgconf%g" \ 100 -e "s%@HOST_DIR@%$(HOST_DIR)%g" \ 101 -e "s%@STAGING_DIR@%$(STAGING_DIR)%g" \ 102 -e "s%@STATIC@%$(if $(BR2_STATIC_LIBS),true,false)%g" \ 103 $(TOPDIR)/support/misc/cross-compilation.conf.in 104endef 105 106define PKG_MESON_CROSSCONFIG_SED 107 -e "s%@TARGET_CC@%$(TARGET_CC)%g" \ 108 -e "s%@TARGET_CXX@%$(PKG_MESON_TARGET_CXX)%g" \ 109 -e "s%@TARGET_AR@%$(TARGET_AR)%g" \ 110 -e "s%@TARGET_STRIP@%$(TARGET_STRIP)%g" \ 111 $(call PKG_MESON_CROSSCONFIG_SED_COMMON,$(1),$(2),$(3),$(4)) 112endef 113 114define PKG_MESON_CROSSCONFIG_SED_CUSTOM 115 -e "s%@TARGET_CC@%$($(1))%g" \ 116 -e "s%@TARGET_CXX@%$($(2))%g" \ 117 -e "s%@TARGET_AR@%$($(3))%g" \ 118 -e "s%@TARGET_STRIP@%$($(4))%g" \ 119 $(call PKG_MESON_CROSSCONFIG_SED_COMMON,$(5),$(6),$(7),$(8)) 120endef 121 122################################################################################ 123# inner-meson-package -- defines how the configuration, compilation and 124# installation of a Meson package should be done, implements a few hooks to 125# tune the build process and calls the generic package infrastructure to 126# generate the necessary make targets 127# 128# argument 1 is the lowercase package name 129# argument 2 is the uppercase package name, including a HOST_ prefix 130# for host packages 131# argument 3 is the uppercase package name, without the HOST_ prefix 132# for host packages 133# argument 4 is the type (target or host) 134################################################################################ 135 136define inner-meson-package 137 138# 139# Configure step.
