关于 .NET Core SDK 3.1在鲲鹏上的安装部署

.NET Core SDK为.NET Core提供最基础的开发支持。

1.替换/usr/lib64目录下的libstdc++.so.6，默认的libstdc++.so.6包含的GLIBC版本无法满足.NET Core SDK 3.1的运行:

strings /usr/lib64/libstdc++.so.6 | grep GLIBC #通过命令验证GLIBC的版本

cd /usr/lib64

cp libstdc++.so.6 libstdc++.so.6.old

rm -f libstdc++.so.6

wget https://obs-mirror-ftp4.obs.cn-north-4.myhuaweicloud.com/libstdc%2B%2B.so.6

2.下载.NET Core SDK 3.1包并解压

wget https://dotnet.microsoft.com/download/dotnet-core/thank-you/sdk-3.1.201-linux-arm64-binaries

mkdir -p /opt/dotnet

tar -zxvf dotnet-sdk-3.1.201-linux-arm64.tar.gz -C /opt/dotnet

#配置环境变量

vim /etc/profile

#在文件的最后加上如下内容

export DOTNET_ROOT=/opt/dotnet

export PATH=$PATH:/opt/dotnet

#wq退出保存

source /etc/profile

#运行dotnet --info命令会报错，提示缺少ICU

dotnet --info

Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

3.安装配置ICU

wget https://github.com/unicode-org/icu/releases/download/release-59-2/icu4c-59_2-src.tgz

tar -xzvf icu4c-59_2-src.tgz

cd icu/source

./configure --prefix=/usr/local/icu

make -j4

make install

#配置环境变量

vim /etc/profile

#在文件的最后加上如下内容

export PATH=$PATH:/usr/local/icu/bin

#创建软链接

ln -s /usr/local/icu/lib/libicutu.so.59 /lib64/

ln -s /usr/local/icu/lib/libicui18n.so.59 /lib64/

ln -s /usr/local/icu/lib/libicuuc.so.59 /lib64/

ln -s /usr/local/icu/lib/libicudata.so.59 /lib64/

icu-config --version #查看ICU版本

icuinfo #验证是否安装成功

dotnet --info #显示如下信息代表安装成功
