Errors building Protobuf 3.5.1 with Visual Studio 2005

[Eric Pederson]

Hi all:

I am trying to build Protobuf (3.5.1) using Visual Studio 2005 (I know, it's ancient, but we are stuck with it for now).  I am getting these errors:

Compiling... main.cc src\google/protobuf/stubs/hash.h(309) : error C2977: 'stdext::hash_map' : too many template arguments C:\Program Files (x86)\Microsoft Visual Studio 8\VC\include\hash_map(89) : see declaration of 'stdext::hash_map' src\google/protobuf/stubs/hash.h(319) : see reference to class template instantiation 'google::protobuf::hash_map' being compiled src\google/protobuf/stubs/hash.h(309) : error C2955: 'stdext::hash_map' : use of class template requires template argument list C:\Program Files (x86)\Microsoft Visual Studio 8\VC\include\hash_map(89) : see declaration of 'stdext::hash_map' src\google/protobuf/stubs/hash.h(311) : error C2977: 'stdext::hash_map' : too many template arguments C:\Program Files (x86)\Microsoft Visual Studio 8\VC\include\hash_map(89) : see declaration of 'stdext::hash_map'

Is there a workaround for this?   Or is Protobuf 3 not compatible with VS 2005?   I am able to build Protobuf 2.6.1 with VS 2005.

If you have to use vs2005, protobuf 2.6.1 might be the latest version you can use. From protobuf 3.0.0, we require at least vs 2008 to build.

From the error messages, it appears that the problem may be due to hitting some internal compiler limits.  Just a wild thought, but you might try compiling just the protobuf code itself with vs 2008 or mingw gcc to create binary object files or perhaps a dll, and see if the result will link with the rest of your project, compiled with vs 2005.
