Yep, sure did, and the header directory is there.
Note that the libraries are getting picked up (otherwise there'd be a LOT of errors)
The header you referenced is NOT in the directory referenced...
The definition IS, however, in libtomcrypt-1.06/src/headers/tomcrypt_math.h, which is included by libtomcrypt-1.06/src/headers/tomcrypt.h - but it won't be picked up as the predicate IFDEF is not set.
Is there a versioning problem here between the libraries I got and what I need?
