CentOS7下.Net 5.0 6.0服务调用System.Drawing.Graph生成验证码图片，异常报错处理

1.yum install libgdiplus --应该是先更新yum

2.如果报错安装
yum install epel-release

后再

yum install libgdiplus

3.libgdiplus的几个依赖

yum -y install autoconf automake libtool

yum -y install freetype-devel fontconfig libXft-devel

yum -y install libjpeg-turbo-devel libpng-devel giflib-devel libtiff-devel libexif-devel

yum -y install glib2-devel cairo-devel

yum -y install mlocate

 

ln -s /usr/lib64/libgdiplus.so /usr/lib64/gdiplus.dll

或者

cd /usr/lib && ln -s libgdiplus.so gdiplus.dll

 

4.如果还有错误

yum install libgdiplus-devel  

5.如果还有错误

vim dx.h5.api.runtimeconfig.json
