Install component's IDL
| Note |
|---|
| In case you haven't done this step already, you must Build and install IDL first. |
Create component
| Code Block |
|---|
|
cd ~/workspace
getTemplateForDirectory MODROOT_WS cppHelloComp
cd cppHelloComp/src
touch HelloComponentImpl.cpp
touch ../include/HelloComponentImpl.h
vim Makefile |
...
| Code Block |
|---|
|
vim ../include/HelloComponentImpl.h |
| Code Block |
|---|
| language | pycpp |

#ifndef _HELLO_COMPONENT_IMPL_H
#define _HELLO_COMPONENT_IMPL_H
#ifndef __cplusplus
#error This is a C++ include file and cannot be used from plain C

class HelloComponentImpl : public virtual acscomponent::ACSComponentImpl, public virtual POA_workshop::HelloComponent {
public:

}

Compile component
| Code Block |
|---|
|
make all install |
Add component to CDB
| Code Block |
|---|
|
vim $ACS_CDB/CDB/MACI/Components/Components.xml |
Add the following item:
| Code Block |
|---|
| language | bash |
|---|
| title | Components.xml |
|---|
|
<e Name="HelloWorldCPP"
Code="HelloComponentImpl"
Type="IDL:acsws/workshop/HelloComponent:1.0"
Container="bilboContainer" ImplLang="cpp" /> |
Testing
Create client python file:
| Code Block |
|---|
|
cd ~/workspace
touch client.py
vim client.py |
We fill it as follow:
| Code Block |
|---|
| language | py |
|---|
| title | ~/workspace/client.py |
|---|
|
from Acspy.Clients.SimpleClient import PySimpleClient
client = PySimpleClient()
component = client.getComponent("HelloWorldCPP")
print(component.printHello()) |
Run component:
| Code Block |
|---|
|
# in one terminal
acsStop
acsStart
# in a different terminal
acsStartContainer -cpp bilboContainer
# in a different terminal
python client.py |
Example output:
| Code Block |
|---|
...
Hello World!
...export INTROOT=~/workspace/introot
export LD_LIBRARY_PATH=$INTROOT/lib:$LD_LIBRARY_PATH
make all install |
