公司同事弄了個華爲雲的ARM64服務器，讓我幫忙部署咱們的服務，因此先試用了一下。
整體感受還行，使用的CentOS系統，yum也能用，epel源也能夠用。可是SCL軟件集用不了。node

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

服務器配置還行，內存又13G多，4核心的CPU，可是這裏看不到CPU的頻率。
由於整體性能還行，也可以安裝clang，因此編譯代碼能夠直接在上面進行，不須要在本地交叉編譯了。
安裝了一下clang，而後編譯了一下gdal-2.4.1.tar.gz 試了一下。
所有命令記錄以下：ios

# 安裝編譯環境
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

# 安裝依賴項
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

# 下載源碼包
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
# 順利生產GDALmake.opt後，修改它，把gcc替換爲clang，g++替換爲clang++，並在CXXFLAGS中添加 -I/usr/include/c++/v1

# 編譯(4核心，應該用四個線程進行編譯的)
make

速度很慢，因此我直接把它丟後臺去跑了。晚上11點多開始跑的，到早上九點半還沒跑完。
編譯期間CPU任務狀態c++
