Customer was validating that RCPL 11 config/build still produces the same output as it did prior to upgrading to RCPL13. Found that it does not.


Reinstalling RCPL 11

Steps to Reproduce

I have two separate projects, but they share a common 
/opt/WindRiver7 directory that includes the installation of RCPL11 and 

Here is how to reproduce the problem: 
1. Start with a /opt/WindRiver7 with only RCPL11 installed 
2. Create a project with the vanilla script attached. It requires none of 
our layers and uses only the most basic options (NOTE the command- 
line option of the workspace number): 
mkdir -p /opt/workspace1/project
cd /opt/workspace1/project
~/ 1 
3. Build the kernel source code up to the kernel metadata task. This 
avoids any patching whatsoever: 
cd /opt/workspace1/project
make linux-windriver kernel_metadata 
4. Update/upgrade /opt/WindRiver7 to RCPL13. 
5. Create a new project with the vanilla script attached and build the 
same recipe. Keeping in mind that it still says 'with-rcpl-version-0011". 
mkdir -p /opt/workspace2/project 
cd /opt/workspace2/project 
~/ 2 
make linux-windriver kernel_metadata 

Now, compare the kernel source code at
You will note that roughly 100 source files differ between the two. 

To maintain building old release sanity, these two should not differ in 
any way.
