Re: [Openexr-devel] undefined symbol: _ZN9IlmThread5MutexD1Ev on exit

[Richard Addison-Wood]

Hi Paul,

For your plugin that provides EXR support, are you linking with dynamic 
versions (.so) or static versions (.a) of the libImf* libraries?

Which options are you using when linking the plugin?

What does this:

readelf -d /path/to/plugin

report?
