[Openexr-devel] Small fix for OpenEXR compile error

[Ejner Fergo]

Hola,

I just tried to compile OpenEXR from
https://github.com/openexr/openexr on Fedora 17 64bit but got an
error:


/bin/sh ../libtool --tag=CXX   --mode=compile g++ -DHAVE_CONFIG_H -I.
-I../config -pthread -I/usr/local/include/OpenEXR -I.. -I../config
-pipe -g -O2 -MT ImfHuf.lo -MD -MP -MF .deps/ImfHuf.Tpo -c -o
ImfHuf.lo ImfHuf.cpp
libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../config -pthread

.libs/ImfHuf.o

./ImfAutoArray.h: In instantiation of 'Imf::AutoArray<T,
size>::AutoArray() [with T = int; int size = 65537]':

./ImfAutoArray.h:60:40: error: 'memset' was not declared in this
scope, and no declarations were found by argument-dependent lookup at
the point of instantiation [-fpermissive]


I could fix it by including string.h in ImfAutoArray.h so very easy (I
wouldn't call myself a developer!). Here's the diff:

Hope this is useful to you.
