[fpagliughi]

Any updates on this?

It appears that the Paho C library is not being linked in along with the std C library, maybe. Any Windows users have any ideas about this?

[mercatorgeo]

Are there any updates / workarounds for this? I'm using Paho cpp and c along with Openssl for my project (all statically linked with /MT) and am getting the exact same error and can't see how to solve it.
