Ok awesome, thanks. I'll try it out right away.

Regarding the version number, when I was fiddling around trying different strategies to get it to compile, I used release_32 as well. If I remember correctly, that also gave me similar issues, so I abandoned that line of thought.

I'm not surprised.  DSA was written before LLVM became really pedantic on warnings and errors, and this particular issue is a real pain to fix, IIRC.

Let me know if removing those flags fixes the problem (it should, but I'd like verification).  If it does, I'll change the Makefiles to omit them.

Thanks again!

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.
