<br>
I have attached the version generated by ccmake for this file:<br>
<br>
Modules/ThirdParty/KWSys/src/KWSys/CMakeFiles/itksys.dir/flags.make<br>
<br>
Note it has a -std=c++11 in the C flags. Any thoughts on why it's there<br>
and how to remove it?<br>
<br>
I don't have C_FLAGS set anywhere, and it doesn't appear in the ccmake<br>
screen (although neither does my CXX_FLAGS and it shows up, so who knows).<br>
<br>
Thanks again,<br>
