#Goal for this example:
|
|
# 1. Build two static libraries that defines multiple methods and kernels
|
|
# 2. Resolve the device symbols into the second static library, therefore
|
|
# confirming that the first static library is on the device link line
|
|
# 3. Verify that we can't use those device symbols from anything that links
|
|
# to the static library
