<div dir="ltr"><div><div>I would start by looking at exactly what the `triple` is for your target. It is plausible that the precise name&number of your system isn't supported - I know nothing of Sparc support, just that (sometimes) you only need a minor letter/digit away from the supported platform(s) to get this sort of problem. Building Clang + LLVM with debug symbols and going back up the call-stack to see exactly where it fell over would help - sometimes there's even comments to help out there... :)<br><br></div>It's quite plausible, if you know enough about the processor architectures, that you can pick a "nearby relative" and specify "-target=ABC" to work around the problem. But without knowing WHAT you are running on, I doubt anyone can give precise help. <br><br>--<br></div>Mats<br></div><div class="gmail_extra"><br><div class="gmail_quote">On 1 February 2016 at 02:56, Dave Ryan via llvm-dev <span dir="ltr"><<a href="mailto:llvm-dev@lists.llvm.org" target="_blank">llvm-dev@lists.llvm.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div link="#0563C1" vlink="#954F72" lang="EN-US"><div><p class="MsoNormal">All,<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I successfully compiled all of llvm, clang etc for Solaris SPARC however when I try and compile with clang I get ‘Unsupported architecture’.
