Hello,<br>
<br>
I pushed some code yesterday and it's causing a couple problem. It seems simple enough. Whats the best way to express this?<br>
<br>
// MAGIC_NUMBER = 16777214 ( little endian )<br>
const char buffer[3] = { 0xFF, 0xFF, 0xFE};<br>
<br>
<br>
ERROR:<br>
/Users/builder/external/ITK/Modules/IO/Mesh/src/itkFreeSurferBinaryMeshIO.cxx:311:31: error: constant expression evaluates to 255 which cannot be narrowed to type 'char' [-Wc++11-narrowing]<br>
const char buffer[3] = { 0xFF, 0xFF, 0xFE};<br>

<br>
Thanks for your suggestion.<br>
