libprotobuf.lib, 29mb?

[Alex Black]

I'm on windows, using Visual Studio 2008 SP1, compiling a Release x64
build of libprotobuf. The lib file is 29,570KB big, is that
expected?

I'm using the provided visual studio projects, but I added the x64
configuration to them, perhaps I have some options set incorrectly or
something.

(The debug lib is 33,575KB)

thanks!

I was going to say "no way", but sure enough, the 32-bit release build is 18,154k, so 64-bit could easily be double that.  However, when you actually link a binary with the library, the size is much smaller.  protoc.exe, for example, is 1MB, and it includes both libprotobuf.lib and libprotoc.lib, the latter of which is 10MB.

I don't know much about MSVC, but perhaps it is including some sort of debug info in this library?  Cygwin produces a 14MB libprotobuf.a, but after stripping it is down to 968k.

Note that I consider 1MB to be too big for many users, which is why the next version will have a "lite" mode that sheds all the descriptors and reflection features and should be very small.

Thanks Kenton, thats reassuring.
