Re: [Openexr-devel] Iex linking errors on OSX

[Piotr Stanczyk]

Hi Richard,

I try to filter out the bigger changes in the Changelogs, but having said that I don't always get a chance to keep those up to date.
The biggest changes are to the SIMD reworking and Cmake paths. There have also been a few additions to the PyIlmBase files that include some threaded implementations of various data types.

Hi Piotr,

Where is the best place to see a summary of the changes for 2.1.0?

All good?

We're looking at releasing 2.1.0 in a matter of weeks so if there are issues please holler

(I am looking at the Alembic mailing list also in regards to the namespace symbol problems people have had and have a fix for the explicit use of Imath:: in one of the PyIlmBase files coming shortly... )

The problem was that I didn't update my build system to include the new IexMath library.  Sorry for the noise!

I wonder if your clang++ build would want:

IEXMATH_EXPORT
int getMathExcOn();

in IexMathFloatExc.h to have IEXMATH_EXPORT be #defined as extern instead of an empty string so that it treats getMathExcOn() as global?

Hey Folks,

I get the following errors when trying to link PyAlembic on top of Iex using ilmbase 2.0.1, when building on OSX Mavericks with clang++ and -std=c++11:

Undefined symbols for architecture x86_64:
"Iex_2_0::getMathExcOn()"

I checked the link order, and the library is included in the right place. I checked the symbols in libIex.a, and they are plenty of Iex_2_0:: symbols, just not this one.

What might this be?
