Compiling custom stages in DataStage®

You can set up an environment to compile custom stages by using your dev cluster.

Procedure

Required: Use your dev cluster to set up an environment to compile custom stages.

pod=`oc get pods | grep -i ds-px-default | grep -i px-runtime|awk '{print $1}'`

oc rsh $pod

Copy the makefiles. In this example, the custom operator code is in /mnts/dev/projects/projectName/CustomStage. Replace it with the filepath of your code.
```
cp -rf /opt/ibm/samples/CustomStage /src/HelloWorld/* /mnts/dev/projects/projectName/CustomStage/
```
```
cd /mnts/dev/projects/projectName/CustomStage/
```
In this directory, edit the file FileName to point to the new custom stage source file. For example, if the source file is customstage.C, set OP_SRC_NAME = customstage.
Build the operator.
```
$ sh ./build.sh
```

See the following doit.sh script for an example of how to run these commands from outside the container:

   # cat doit.sh
   pod=`oc get pods | grep -i ds-px-default | grep -i px-runtime|awk '{print $1}'`
   echo $pod
   oc exec  $pod -- bash -c "cp -rf /opt/ibm/samples/CustomStage /tmp; cd
   /tmp/CustomStage/src/HelloWorld; sh ./build.sh"

   # ./doit.sh
