公司同事弄了个华为云的ARM64服务器，让我帮忙部署我们的服务，所以先试用了一下。
总体感觉还行，使用的CentOS系统，yum也能用，epel源也可以用。但是SCL软件集用不了。
uname -a
Linux unispace-arm 4.14.0-115.8.1.el7a.aarch64 #1 SMP Wed Jun 5 15:01:21 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux服务器配置还行，内存又13G多，4核心的CPU，但是这里看不到CPU的频率。
因为总体性能还行，也能够安装clang，所以编译代码可以直接在上面进行，不需要在本地交叉编译了。
安装了一下clang，然后编译了一下gdal-2.4.1.tar.gz 试了一下。
全部命令记录如下：
# 安装编译环境
sudo yum install clang libcxx-devel
sudo update-alternatives --install /usr/bin/cc cc /usr/bin/clang 100
sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/clang++ 100
# 安装依赖项
sudo yum install --downloaddir=./centos.arm64/gdal --downloadonly gdal-devel
cd centos.arm64/gdal
rm gdal-devel-1.11.4-3.el7.aarch64.rpm gdal-libs-1.11.4-3.el7.aarch64.rpm
sudo rpm -ivhU * --nodeps --force
# 下载源码包
wget http://download.osgeo.org/gdal/2.4.1/gdal-2.4.1.tar.gz
tar -xzf gdal-2.4.1.tar.gz
cd gdal-2.4.1
# 生成Makefile
./configure
# 顺利生产GDALmake.opt后，修改它，把gcc替换为clang，g++替换为clang++，并在CXXFLAGS中添加 -I/usr/include/c++/v1
# 编译(4核心，应该用四个线程进行编译的)
make速度很慢，所以我直接把它丢后台去跑了。晚上11点多开始跑的，到早上九点半还没跑完。
