New issue 365 by [email protected]: Unused parameters in repeated_field.h
cause build errors when using clang if -Werror -Wall is enabled
http://code.google.com/p/protobuf/issues/detail?id=365
What steps will reproduce the problem?
1. Create any program which includes google/protobuf/repeated_field.h
2. Attempt to compile said program with Apple clang version 3.0
(tags/Apple/clang-211.12) (based on LLVM 3.0svn)
What is the expected output? What do you see instead?
The program to compile, provided the sources are correct. Instead I get:
/opt/local/include/google/protobuf/repeated_field.h:1197:54: error: unused
parameter 'ignores_parameter' [-Werror,-Wunused-parameter]
RepeatedFieldBackInsertIterator<T>& operator++(int ignores_parameter) {
^
/opt/local/include/google/protobuf/repeated_field.h:1228:57: error: unused
parameter 'ignores_parameter' [-Werror,-Wunused-parameter]
RepeatedPtrFieldBackInsertIterator<T>& operator++(int ignores_parameter) {
^
/opt/local/include/google/protobuf/repeated_field.h:1257:11: error: unused
parameter 'ignores_parameter' [-Werror,-Wunused-parameter]
int ignores_parameter) {
What version of the product are you using? On what operating system?
protobuf 2.4.1
OS X 10.7.2
Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn)
(from XCode 4.2.1)
Please provide any additional information below.
https://groups.google.com/forum/#!topic/open-lighting/39Mj0KXlCIk was how I
became aware of the issue.
To work around it I've changed my autoconf macro to s/-I/-isystem / as
suggested in Issue 172.
