crosstool-ng构建sysroot

构建sysroot

推荐使用 Crosstool-ng 来构建 sysroot. 这里是一些配置的例子：

• x86_64-gcc-8.5.0-glibc-2.28
• aarch64-gcc-8.5.0-glibc-2.28
• armhf-gcc-8.5.0-glibc-2.28

准备构建工具

apt-get install -y gcc g++ gperf bison flex texinfo help2man make libncurses5-dev \
python3-dev autoconf automake libtool libtool-bin gawk wget bzip2 xz-utils unzip \
patch rsync meson ninja-build# Compile latest crosstool-ng
git clone https://github.com/crosstool-ng/crosstool-ng.git
cd crosstool-ng
./bootstrap
./configure --prefix=/crosstool-ng/out && make && make install
export PATH=$PATH:/crosstool-ng/out/bin

构建sysroot

mkdir toolchain-dir
cd toolchain-dir
cp <path-to-config-file> .config
ct-ng menuconfig # 刷新保存适合版本配置
ct-ng build
