I try to install Walkaround , a project based on Google Wave. I followed the official wiki for installation.
But during the last step (./runant run), I've 100 errors:
Proto.java:7: package com.google.protobuf does not exist
com.google.protobuf.ExtensionRegistry registry) {
^
Proto.java:12450: package com.google.protobuf.Descriptors does not exist
private static com.google.protobuf.Descriptors.Descriptor
^
Proto.java:12453: package com.google.protobuf.GeneratedMessage does not exist
com.google.protobuf.GeneratedMessage.FieldAccessorTable

100 errors
Similar topic: Problems using protobufs with java and scala . So I try this solution after searching a proto.jar and the Proto.java:
javac -cp
~/walkaround/third_party_src/wave/trunk/dist/proto.jar
~/walkaround/proto_src/com/google/walkaround/proto/Proto.java
But I get the same 100 errors.
Someone can help me? I have no knowledge about Ubuntu Linux and Java environment.
I had the same problem. The reason on my Project was that ./get-third-party-deps failed. That was fixed by installing build-essential on my ubuntu machine
sudo apt-get install build-essential
./get-third-party-deps
You may jar xf proto.jar to see if those classes are in the jar.
If there is anything wrong, you may get it from http://code.google.com/p/protobuf/source/checkout
It contains c and java source code, you need java parts.
