Variable unitialized warnings during compilation of Rosetta 3.5

[Anonymous]

I am getting a lot of “unitialized” warnings during compilation of rosetta 3.5. See examples below (there is a lot more). I am using Ubuntu 14.04 amd64. I have gcc 4.8 and 4.7 installed. I am compiling with ./scons.py -j1 mode=release cxx_ver=4.7 bin.

Those shouldn’t be a problem, so long as they’re just warnings. A good way to check is to re-run the (identical) scons command again after it completes. If you continue to get errors, then there’s a problem. If things compiled, you’ll get a few brief messages from the scons system, but no compiler commands printed, and no messages about warnings or errors.
