<div>Yes, it looks like you're missing system headers for 32-bit builds.</div><div>Is there any way/package you can use to get them? (probably there should be folder /usr/include/i386-linux-gnu/</div><div>as well as /usr/include/x86_64-linux-gnu).</div>
<div>In the meantime, we should think on how to test presence of necessary headers while configuring the build...</div><div><br></div><div>On Fri, Oct 5, 2012 at 12:11 AM, kapamaroo <span dir="ltr"><<a href="mailto:kapamaroo@gmail.com" target="_blank">kapamaroo@gmail.com</a>></span> wrote:</div>

I get this error in debian unstable (arch amd64).<br>
<br>
COMPILE: clang_linux/asan-i386/i386: /opt/llvm/projects/compiler-rt/lib/asan/asan_linux.cc<br>

libc6-dev<br>
libc6-dev-i386<br>
<br>
Build fails after the following changes<br>
<br>
r165096 "Build ASan runtime on Linux for both x86_64 and i386, same as we do with full compiler_rt and<br>
libprofile"<br>
r165097 "Make sure 32-bit ASan runtime is available on 64-bit Linux platforms"<br>
<br>
I cannot test it with another linux distribution, so maybe it is debian related or just me.<br>
Maybe I need to enable multiarch support for i386. Anyone with the same problem?<br>
<br>
Thanks,<br>
