Make inline Functions static #28

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Rename Murmurhash3.cpp to Murmurhash3.c
2. Import Murmurhash3.h and Murmurhash3.c into Xcode
3. Attempt to compile it into a project.

What is the expected output? What do you see instead?

Should work, but to errors:

Undefined symbols for architecture i386:
  "_rotl32", referenced from:
      _MurmurHash3_x86_32 in MurmurHash3.o
      _MurmurHash3_x86_128 in MurmurHash3.o
  "_rotl64", referenced from:
      _MurmurHash3_x64_128 in MurmurHash3.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

What version of the product are you using? On what operating system?

Copied from Subversion today (2014-05-05). Xcode 5.1.1.

Please provide any additional information below.

Was able to get it to work by making those functions static:
