折腾了几天，并且在永良和大神Mark Rivers的帮助下，终于编译成功了，下面总结下流程：

准备：openEuler20.03-SP2-LTS的mininstall（可以用中文选项）

root权限下：

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -ivh --nodeps epel-release-latest-7.noarch.rpm

yum install -y git wget gcc gcc-c++ autoconf libtool libX11-devel  libXext-devel libnet-devel libpcap-devel libusbx-devel libusb-devel  intltool  glibmm24-devel procServ re2c readline-devel perl-ExtUtils-Install make

yum install -y ninja-build meson glib2-devel libxml2-devel gtk3-devel gstreamer1 gstreamer1-devel gstreamer1-plugins-base-devel libnotify-devel gtk-doc gobject-introspection-devel zlib-devel

#上面几条命令注意提示，是否安装齐全，可能按提示要加--nobest选项

##需要的包参考： Packages required for EPICS on Centos 8 — EPICS How-Tos documentation

adduser ioc

mkdir /half          #以合肥先进光源为例

chown -R ioc:ioc /half

cd /half

su ioc

mkdir epics

cd epics

########下载和编译epics base7########

##git抓包不顺的话需要翻墙VPN

git clone --recursive -b 7.0 https://git.launchpad.net/epics-base base

cd base

make

来自 <EPICS 7 - EPICS Controls/>

######下载和修改synApps的脚本(当前最新版是6.2 --2021.12.20)#####

# 1. download the installer script
wget https://raw.githubusercontent.com/EPICS-synApps/support/master/assemble_synApps.sh

# 2. edit assemble_synApps.sh for your version of EPICS base and local directory paths

# 3. (optional) Specify the (new) directory name where synApps will be installed.
#    This is the default:
#    export SYNAPPS_DIR=synApps
#    This directory will be created when assemble_synApps.sh is run.

# 4. download & install the synApps source files:

# 来自：GitHub - EPICS-synApps/support: APS BCDA synApps module: support

修改这个文件，我是按下面截图注释掉不需要的模块，可以注释掉更多就能少下载些：

bash ./assemble_synApps.sh           #一次可能不能把所有的包抓下来，多运行几次

之后进入support目录：

make release

vi areaDetector-R3-11/configure/CONFIG_SITE.local

和以前的流程相比多了这部分，上面的截图是Mark帮助修改的选项，下面是永良踩坑帮总结的几条命令： 

sudo yum install -y rpcgen libtirpc libtirpc-devel

sudo In-s /usr/include/tirpc/netconfig.h /usr/include/

sudo cp /usr/include/tirpc/rpc/* /usr/include/rpc/

make LDFLAGS=-ltirpc

之后安装aravis驱动，root权限下：

取ADGenICam — areaDetector 3-11-2-gf866e7e documentation 里的这部分即可：

cd /usr/local

git clone https://github.com/AravisProject/aravis

cd aravis/

meson build

cd build

ninja-build

ninja-build install

编译ADGenICam和ADAravis，普通用户权限运行：

cd /half/epics/synApps/support/areaDetector-R3-11/
git clone https://github.com/areaDetector/ADGenICam.git
cd ADGenICam/

make

cd ..

git clone https://github.com/areaDetector/ADAravis.git
cd ADAravis/
make

至此编译环节就都结束了，后面参照：海康摄像头 EPICS的ADAravis的IOC搭建 搭建IOC即可。

GraphicsMagick不知道有什么用，永良带着这个模块编译通过了，我编译synApps过程中怎么也搞不过去，就用了NO，还是喜欢base配合synApps编译的流程，省得单独每个模块下载，还要改很多的配置文件，这个流程里现在只需要改两个文件即可，欢迎路过的愿意用openEuler的按流程跑一遍，有问题随时呼我或永良。
