Hi Renato,
<div class=""><br class="">
</div>
<div class="">I'm assuming this got triggered by <a href="http://llvm.org/viewvc/llvm-project?view=revision&revision=300680" class="">http://llvm.org/viewvc/llvm-project?view=revision&revision=300680</a>, which makes a change to cPerf.cpp in LNT?</div>
<div class=""><br class="">
</div>
<div class="">
<div class="">Strange indeed that this was working before and is now broken.</div>
<div class="">This cPerf.cpp is one of the LNT python submodules, implemented in c++. Therefore, it needs a c/c++ compiler to build the file.</div>
</div>
<div class="">This is all done through Python's built-in mechanisms to do so. I'm assuming that Python will look for the default c/c++ compiler on the platform, which on linux distributions is probably gcc/g++.</div>
<div class="">At <a href="http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/1095/steps/setup lit/logs/stdio" class="">http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/1095/steps/setup%20lit/logs/stdio</a>, I see the error message
is:</div>
<div class="">
<pre style="font-family: 'Courier New', courier, monotype, monospace; font-size: medium; orphans: 2; widows: 2;" class=""><span class="stderr" style="color: red;">aarch64-linux-gnu-gcc: error trying to exec 'cc1plus': execvp: No such file or directory</span></pre>
<div class="">Is it possible you installed gcc, but not g++?</div>
</div>
<div class=""><br class="">
</div>
<div class="">I see the other bots with "lnt" in the name at <a href="http://lab.llvm.org:8011/builders" class="">http://lab.llvm.org:8011/builders</a> don't have this problem, so I'm assuming getting g++ installed on the bot will solve this issue.</div>
<div class=""><br class="">
</div>
<div class="">Thanks,</div>
<div class=""><br class="">
</div>
<div class="">Kristof.</div>

<div class="">PS. I'm still puzzled that this didn't fail the bot the first time cPerf.cpp was introduced, about a year ago.</div>

<div class="">Hi Kristof,<br class="">

I think this one is yours. :)<br class="">

First, we got errors that GCC is not installed (we use Clang), now it<br class="">
has some cc1 errors. I wonder why this is now a requirement and why it<br class="">
started failing after your patch, since you haven't added anything<br class="">
new...<br class="">
