Re: Can't get lmdb to build on FreeBSD 12

Russell Haley wrote:

Hi,

Sorry for the silly question, but I've stumped myself and my C is
weak. Normally lmdb builds fine without issue on most of the platforms
I try (Debian Jessie, FreeBSD 10.3 & 12), but it's stopped compiling
on my TrueOS box, which is FreeBSD 12. I've tried gcc and clang 4.0
and 3.9.
Try using GNU make. It looks like whatever make you're using doesn't have the proper default build rules.

Any help would be grand.
