that log is most likely not going to help :(

I'm having a similar problem installing node-fann. Here's my log:

Doesn't work for me either. I've tried Node 7 and Node 8 with multiple versions of node-gyp from the latest (3.6.2) down to 2.0.2. This is on Debian Jessie. I've tried the Debian fann libs and also compiling and installing from source. I suspect that v8 has changed the way they do things and that node-fann needs to be updated to conform.
