conan入门(二十七):因profile [env]字段废弃导致的boost/1.81.0 在aarch64-linux-gnu下交叉编译失败

今天在尝试用conan 1.60.0使用aarch64-linux-gnu编译器交叉编译boost/1.81.0时报错了：

conan install boost/1.81.0@ -pr:h aarch64-linux-gnu.jinja -pr:b default --build boost
1

输出如下：

从后面这段可以看出是编译器在编译arm64汇编代码时出错了

如果编译器设置正确应该不会出现这个错误，于是从输出日志再往上找我又找到了这段

果然是使用本机编译器g++而不是交叉编译器 aarch64-linux-gnu-g++

boost是由b2执行编译的，使用哪个编译器由环境变量CC来决定，CC定义在profile,所以问题应该出在profile.

如下是执行aarch64-linux-gnu交叉编译使用的profile,
aarch64-linux-gnu.jinja

include(default)
target_host=aarch64-linux-gnu
[settings]
arch=armv8
build_type=Release
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=5.4
os=Linux
[options]
[env]
CHOST=$target_host
CC=$target_host-gcc
CXX=$target_host-g++
AR=$target_host-ar
AS=$target_host-as
RANLIB=$target_host-ranlib
LD=$target_host-ld
STRIP=$target_host-strip
#########################################################################################
# 指定./conan/cmake/aarch64-linux-gnu.toolchain.cmake 为cmake 工具链文件             #
#########################################################################################
{% set toolchain = os.path.join(profile_dir, "..","cmake","aarch64-linux-gnu.toolchain.cmake") %}
CONAN_CMAKE_TOOLCHAIN_FILE={{ toolchain }}
CONAN_CMAKE_GENERATOR="Unix Makefiles"

这个profile是我一年前写的，当时可以正确执行交叉编译，当然了，那个时候使用的conan 版本是1.45.0,一年多过去了，conan的版本迭代很快，目前我使用的是conan 1.x的接近最新版本1.60.0(1.x下当前最新版本是1.60.2),
会不会是因为版本更新来带的兼容性问题呢？
打开conan官方文档profile相关的页面 https://docs.conan.io/1/reference/profiles.html
第一眼就看到了这个

原来profile中的[env]字段名被废弃了，改为了[buildenv],
再看[buildenv]的说明：从1.35.0开始新增加了这个字段，用于替换[env]

立即把上面aarch64-linux-gnu.jinja profile中的[env]改为[buildenv]再如下执行boost交叉编译通过

conan install boost/1.81.0@ -pr:h aarch64-linux-gnu.jinja -pr:b default --build boost
