Thanks, this helped.

I got around the liblzo2.a issue by just building from the sources:

mkdir lzo2_temp
cd lzo2_temp/
yumdownloader --source lzo-devel
pm2cpio lzo-2.08-8.fc24.src.rpm | cpio -idv
tar xf lzo-2.08.tar.gz
cd lzo-2.08/
run ./configure if need-be
make liblzo2.a

Looks like all I need is liblzo2.a.  Seems like a simple thing for the
.rpm package to include since it's already been designed into the
Makefile in the src.rpm.

Anyways, I think I may have it working now, despite the same compiler
warnings I mentioned at the beginning??:

[~]$ ./crash src/linux/vmlinux crash.dump
