New issue 276 by pvegd...@gmail.com: Windows paths should not be case
sensitive for protoc command line.
What steps will reproduce the problem?
1. Write a proto file.
2. Call protoc using a case sensitivity difference for the --proto_path and
the input file. For example:
protoc.exe --proto_path=c:\ExampleSln\src\ --cpp_out=c:\ExampleSln\src\
(Note the use of both "c:" and "C:")
What is the expected output? What do you see instead?
I expect the creation of Dummy.pb.cc and Dummy.pb.h. Instead, I get the
following error message:
C:\ExampleSln\src\Proto\Dummy.proto: File does not reside within any path
specified using --proto_path (or -I). You must specify a --proto_path
which encompasses this file. Note that the proto_path must be an exact
prefix of the .proto file names -- protoc is too dumb to figure out when
two paths (e.g. absolute and relative) are equivalent (it's harder than you
What version of the product are you using? On what operating system?
This was tested on version 2.4 of protoc on Windows XP.
Please provide any additional information below.
This is a particular problem because of .rules files in Visual Studio
2008. Attempting to generate files relative to a directory other than the
directory containing the .proto files leads to a case mismatch because
$(ProjectDir) and $(SolutionDir) use different cases for drive letters.
