关于介子，交叉文件和STM32

问题描述

我对与介子交叉编译STM32有一些问题。我是介子的新手，请尝试使用它来编译STM32代码。我找到了这个存储库https://github.com/hwengineer/STM32F3Discovery-meson-example 并尝试更改它，我需要它。

我的交叉文件就像

[binaries]
c       = 'arm-none-eabi-gcc'
cpp     = 'arm-none-eabi-g++'
ld      = 'arm-none-eabi-ld'
ar      = 'arm-none-eabi-ar'
as      = 'arm-none-eabi-as'
size    = 'arm-none-eabi-size'
objdump = 'arm-none-eabi-objdump'
objcopy = 'arm-none-eabi-objcopy'
strip   = 'arm-none-eabi-strip'
gdb     = 'arm-none-eabi-gdb'
terminal= 'x-terminal-emulator'
openocd = '/usr/local/bin/openocd'

exe_wrapper = 'meson_exe_wrapper.sh'

[properties]
c_args      = [
               '-mthumb',# define language
               #------------------------------------
               '-fshort-enums',# otherwise errors at linking...
               '-fmessage-length=0',# all error warnings in a single line (default 72)
               '-fsigned-char',# char is per default unsigned
               '-ffunction-sections',# each function to a seperate section ==> Code-optimization / deletion
               '-fdata-sections',# each variable to a seperate section ==> Code-optimization / deletion

              '-Wall','-ffreestanding',#------------------------------------
               # '-flto',]

c_link_args = [
                '-nostdlib',# do not import the standard library's
               # '-flto',]

[host_machine]
system     = 'none'
cpu_family = 'arm'
cpu        = 'cortex-m3'
endian     = 'little'

但是当我尝试编译介子时，会给出

Build type: native build
Project name: thermometer_with_meson
Project version: undefined
C compiler for the host machine: cc (gcc 10.2.0 "cc (GCC) 10.2.0")
C linker for the host machine: cc ld.bfd 2.35
Host machine cpu family: x86_64
Host machine cpu: x86_64

主机应为arm cortex-m3，但似乎有误。

为什么介子会忽略交叉文件？为什么要使用主机x86-64？

顺便说一句，它给出了错误，例如x86_64应该是x86-64。

解决方法

据我所见，输出日志中有

Build type: native build

但是，您应该：

Build type: cross build

因此，检查构建的配置方式，应将交叉文件设置为安装构建目录，然后将其用于构建：

$ meson build/ --cross-file cross_file.build
$ ninja -C build/
