version of protobuf is too old

[pavelvat]

protobuf.mk currently have version 2.5.0 this leads to incompatibility when build of Clementine: http://pastebin.com/Zr17VsL9
I tried to upgrade protobuf.mk to version 2.6.1 and encountered with a very strange problem http://pastebin.com/cb19jtvt
./autogen.sh trying to download http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2 and fail. gtest-1.5.0.tar.bz2 is successfully downloaded through internet browser or command line (curl, wget), but it fail when downloading inside MXE.

Workaround for this problem:

wget http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2
tar fjx gtest-1.5.0.tar.bz2
wget https://github.com/google/protobuf/archive/2.6.1.tar.gz
tar fzx 2.6.1.tar.gz
cp -r protobuf-2.6.1/ protobuf-2.6.1.orig
cp -r gtest-1.5.0 protobuf-2.6.1/
diff -Naur protobuf-2.6.1.orig/ protobuf-2.6.1 > protobuf-1-fixes.patch
cp protobuf-1-fixes.patch /path/to/mxe/src/

clementine.exe was built and launched successfully.

The same problem with protobuf.mk version 3.0.0-beta-2, but with another link https://googlemock.googlecode.com/files/gmock-1.7.0.zip.

MXE has a protection against (potentially unverified) downloads during building.

You should create package gtest and unpack its source while building protobuf. It can be done with macro PREPARE_PKG_SOURCE. For example, package upx unpacks source of package uxl. Add gtest to dependencies of protobuf.
