With 4.8.2 - I built ITK with C++11 (this required -fpermissive to
complete)<br>
Despite doing that, I was still unable to built ITK applications
with C++11 (even when also using -fpermissive). <br>
<br>
Let me know if you've had different results. I was hoping this would
be resolved with 4.9. <br>

Hello,

Hans, based on the release schedule it looks like that
will be out pretty soon. <br class="">
<br class="">
That's a big improvement to ITK to add c++11 support in
my opinion. Thanks. <br class="">

Linux c++11 build issue v4.8.2<br class="">
</div>

<div bgcolor="#FFFFFF" text="#000000" class="">Dear
Insight Developers<br class="">
<br class="">
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 class="">
<br class="">
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}
-std=c++11"<br class="">
<br class="">
I can compile ITK applications when not using
this flag. <br class="">
<br class="">
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
class="">
<br class="">
Any suggestions would be welcome. Thanks<br
class="">
<br class="">
