# Run this script to regenerate descriptor.pb.{h,cc} after the protocol
|
|
# compiler changes. Since these files are compiled into the protocol compiler
|
|
# itself, they cannot be generated automatically by a make rule. "make check"
|
|
# will fail if these files do not match what the protocol compiler would
|
|
# generate.
|
|
|
|
# Note that this will always need to be run once after running
|
|
# extract_from_google3.sh. That script initially copies descriptor.pb.{h,cc}
|
|
# over from the google3 code and fixes it up to compile outside of google3, but
|
|
# it cannot fix the encoded descriptor embedded in descriptor.pb.cc. So, once
|
|
# the protocol compiler has been built with the slightly-broken
|
|
# descriptor.pb.cc, the files must be regenerated and the compiler must be
|
|
# built again.
