准备：

Centos7ministall的系统：

root权限下：

yum install -y epel-release

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

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

##需要的包参考： https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/linux-packages.html

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 base#################################

git clone -b 3.15 https://git.launchpad.net/epics-base

cd epics-base

make

来自 <https://epics-controls.org/resources-and-support/base/series-3-15/>

或者：

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

make

来自 <https://epics-controls.org/resources-and-support/base/epics-7/>

选择3.15或7编译，或者分别编译，再把某一个ln -s 到base

After compiling you should put the path into $HOME/.profile or into $HOME/.bashrc by adding the following to either one of those files:

export EPICS_BASE=${HOME}/EPICS/epics-base
export EPICS_HOST_ARCH=$(${EPICS_BASE}/startup/EpicsHostArch)
export PATH=${EPICS_BASE}/bin/${EPICS_HOST_ARCH}:${PATH}

EpicsHostArch is a program provided by EPICS that returns the architecture of your system. Thus the code above should be fine for every architecture.

之后按上面配好环境变量

############上面是下载和编译base##########################

没有意外的话，上面应该把base编译通过了。

############下载和编译synApps(当前最新版是6.1 --2020.7.15)#############

# 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:
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

make

来自 <https://github.com/EPICS-synApps/support>

之后下载aravisGigE:

wget https://github.com/areaDetector/aravisGigE/archive/R3-0.tar.gz

解压到areadetector 目录下

之后进入aravisGigE：

./install.sh

make

至此aravisGigE应该编译通过了，下面就可以添加摄像头了：

Adding a new camera

• Run bin/linux-x86/arv-tool-0.2 -n "" genicam > ".xml" to download the genicam xml data from the selected device cameras

  • E.g. bin/linux-x86/arv-tool-0.2 -n "Allied Vision Technologies-50-0503318719" genicam > AVT_Manta_G125B.xml

• Make sure the generated file doesn't have a space at the start of it

• Run aravisGigEApp/src/makeDbAndEdl.py

  • E.g. aravisGigEApp/src/makeDbAndEdl.py AVT_Manta_G125B.xml AVT_Manta

• This should then create:

  • aravisGigEApp/Db/.template
  • aravisGigEApp/opi/edl/.edl
  • aravisGigEApp/opi/edl/-features.edl

• Once you have decided on the most useful features, copy them from -features.edl and paste them into .edl in order to create a useful summary screen

• If you are using medm, or want to generate CSS-Boy or caQtDM screens from medm screens then run aravisGigEApp/src/makeAdl.py . This will generate -features_1.adl through -features_N.adl, where N depends on the number of features and the maximum screen width and height set in makeAdl.py.

• Once you have decided on the most useful features, copy them from -features_*.adl into a new file called -features.adl in order to create a useful summary screen.

cd /half/epics/synApps/support/areaDetector-master/aravisGigE/bin/linux-x86_64

没发现设备，需要关闭防火墙：

systemctl disable firewalld

systemctl stop firewalld 之后：

之后：

会在/half/epics/synApps/support/areaDetector-master/aravisGigE/aravisGigEApp/Db生成template文件，copy至/half/epics/synApps/support/areaDetector-master/aravisGigE/db

之后修改：/half/epics/synApps/support/areaDetector-master/aravisGigE/iocs/aravisGigEIOC/iocBoot/iocAravisGigE/st.cmd：

aravisCameraConfig("$(PORT)", "Hikvision-00D22036189")

dbLoadRecords("$(ARAVISGIGE)/db/HIK720.template","P=$(PREFIX),R=cam1:,PORT=$(PORT),ADDR=0,TIMEOUT=1")

load相应摄像头的template和摄像头代号，之后./start_epics就可以运行起IOC了。

以上过程在Centos7下都通过了。尝试过在centos8下做，但是在tirpc那卡住了，有空的可以在8上试试。
