Thanks for answering, but this code compiles fine with
this command below, thus I do not understand your
point on the include path? (there is no private
includes in this code)<br>

The verbose option on the command that is ok.<br>

CFE list<br>
<br>
Sorry to post again this post, but I am
really stacked on this problem.<br>
<br>
I have an issue compiling a small c++
program with clang++-3.8 on Ubuntu trusty<br>
<br>
Using the joined c++ program bug.cpp, <br>
<ul>
<li>clang++-3.8 -std=c++11 bug.cpp
compiles fine while</li>
<li>clang++-3.8 -std=c++11
-stdlib=libc++ bug.cpp produces
invalid compile errors.</li>
</ul>
<br>
What could be the problem and how can it
be solved?<br>
<br>
TIA<br>
