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:

llvm[2]: Compiling Printer.cpp for Debug build (PIC)

Any idea what might have gone wrong?

My best guess is that you're compiling with a version of GCC or Clang that is more stringent about warnings and errors than what we use.

I recommend removing -Werror and -Wall from Makefile.common.in and reconfiguring poolalloc.  That should fix the compile.

Also, I realize that I haven't updated the web site documents yet, but you can use the release_32 branch of LLVM, poolalloc, and SAFECode now.  The release_30 branch is frozen.
