Hello @joel , @gedare 

I followed the RTEMS Quick Start guide and built RTEMS 7 from source on my Linux system.

I successfully built the **sparc/erc32 BSP** and the sample applications.

I modified the hello world example located at:

testsuites/samples/hello/init.c

to print a different message.

After rebuilding RTEMS, the samples were generated successfully, including:

build/sparc/erc32/testsuites/samples/hello.exe

I have attached:

* The patch file generated with `git format-patch`
* A screenshot showing the successful build output.

Best regards,\
