Dear Insight Developers<br>
<br>
I have compiled v4.8.2 on Ubuntu 14.04 successfully (g++ 4.8),
however, I get compiler errors when building my own ITK applications
with the following cmake flag<br>
<br>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11"<br>
<br>
I can compile ITK applications when not using this flag. <br>
<br>
I have tried using -fpermissive when building my application. I have
also tried compiling ITK using -std=c++11 -fpermissive, individually
and in combination. I always get the same errors.<br>
<br>
Any suggestions would be welcome. Thanks<br>
<br>
David<br>
