Hey John,

Good news! Removing -Werror and -Wall worked.

But I tried reproducing the error by following the steps again and I wasn't able to.

It looks like release_32 works fine.

I've written up the bug report, but I'm not submitting it as a bug for release_30 because you said that development was frozen. Do you want me to submit it anyway, or is it not required?

Regards,

Vishruth

Sure thing.

I re-configured poolalloc after disabling the -Werror and -Wall.

I'll retry compiling it and then file a report.

Hello,

While following the steps from here to compile poolalloc, I get an error.
I'm not exactly sure what could have gone wrong and I've tried redoing the
steps a few times, without success.

I also get an error while trying to compile safecode.
It seems related an error in Printer.cpp.

My error trace looks like this:

John, Isn't this already fixed?
In http://llvm.org/docs/doxygen/html/GraphWriter_8h_source.html , the
cast is to <const void*>, which should silence the warning.

It might be (provided that this version of GraphWriter is in the release_32 branch of LLVM).  I didn't investigate the details closely.

Vishruth, if you see the error in the release_32 branch on your system, can you file a bug report for it?  Fixing a warning like this is low priority as it is easy to work around, but we should have a bug report to track it.
