I'm using 2.  On gcc version 4.1.2 20080704 (Red Hat 4.1.2-44) it fails.  With 
gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) it seems OK.

What C++ compiler are you using?

Hi everyone,

I'm building openimageio on linux.  In src/include/export.h, OIIO_API gets set 
to to __attribute__ ((visibility ("default"))).

It seems to work fine for functions and classes, but I get warnings and errors 
when this is used with enums.  For example:

imagebufalgo.h:94: warning: type attributes are honored only at type definition
imagebufalgo.h:94: error: use of enum ‘AlignedTransform’ without previous 
declaration
imagebufalgo.h:95: error: expected unqualified-id before ‘{’ token

code looks like:
enum OIIO_API AlignedTransform
{
    TRANSFORM_NONE = 0,
    TRANSFORM_FLIP,        // Upside-down
    TRANSFORM_FLOP,        // Left/Right Mirrored
    TRANSFORM_FLIPFLOP,    // Upside-down + Mirrored (Same as 180 degree 
rotation)
//  TRANSFORM_ROT90,       // Rotate 90 degrees clockwise. Image remains in 
positive quadrant.
//  TRANSFORM_ROT180,      // Rotate 180 degrees clockwise. Image remains in 
positive quadrant. (Same as FlipFlop)
//  TRANSFORM_ROT270,      // Rotate 270 degrees clockwise. Image remains in 
positive quadrant.
};

Is the syntax for ___attribute___ different for enums?  Thanks.

Sheila
