[lldb-dev] Linux Build Errors w/ LLDB

I'm using Clang 3.3, but this looks like it might be a bug with libstdc++ 4.6 (see bottom entry on this page):

http://stackoverflow.com/questions/15747223/why-does-this-basic-thread-program-fail-with-clang-but-pass-in-g

Drat. If this is the case, it's going to cause a lot of people on Ubuntu 12.04 some pain.

In any case, I've reverted back to r192702 for now and am working from there - so I'm not blocked at the moment. Not able to sync really either though. :)

I'm also behind a firewall here at Valve so I can't check to see what the Linux buildbot is doing - I'm guessing it's broken as well?

Thanks Enrico.

Michael,
that is correct

I did make the changes to Init/Terminate because somehow the OSX build was confused as to the absence of a definition at link-time. I sent an email to the list asking if anyone had a proper fix for the issue, however to no avail yet
I am planning to see what is wrong there ASAP today, but if this is blocking you more critically, feel free to revert while I take a closer look

With that said, I am not sure what the other problem is, a GCC bug maybe?

I'm running into these errors while building Linux LLDB with clang 3.3 right now and r192738 for llvm, clang, and lldb:

/home/mikesart/data/src/llvm.svn/llvm/tools/lldb/source/Plugins/Platform/Windows/PlatformWindows.cpp:114:18: error: redefinition of 'Initialize'
/home/mikesart/data/src/llvm.svn/llvm/tools/lldb/source/Plugins/Platform/Windows/PlatformWindows.cpp:133:18: error: redefinition of 'Terminate'

To fix these, I had to undo the change in r192724 (see down below).

I'm also now hitting this error when linking after I fixed the above two though:

/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../include/c++/4.6/chrono:535:6: error: no matching constructor for initialization of 'duration' (aka 'std::chrono::duration<long, std::ratio<1, 1000000> >')
          : __d(__t.time_since_epoch())
            ^   ~~~~~~~~~~~~~~~~~~~~~~

Anyone else seeing this?
Thanks.
