Building/Installing Bitcoin on OpenBSD

Install Bitcoin on OpenBSD 6.0

0. Make sure some dependencies are installed!
  automake (1.15), autoconf (2.69), git, libtool, berkleydb (installed from source 4.8), boost, protobuf, python > 3.5, gmake, leveldb
  5.9 guide: https://github.com/bitcoin/bitcoin/blob/master/doc/build-openbsd.md
1. Clone the repo
  git clone https://github.com/bitcoin/bitcoin.git
2. Checkout newest stable branch (0.13.0 currently)
  git checkout v0.13.0
3. run autogen script
  ./autogen.sh
    Error: Provide an AUTOCONF_VERSION environment variable, please.
3.1 export AUTOCONF_VERSION 2.69
  .autogen.sh
   Error: Provide an AUTOMAKE_VERSION environment variable, please.
3.2 export AUTOMAKE_VERSION 1.15
  .autogen.sh
4. configure
  ./configure
4.1 set CC & CXX vars
  CC=egcc CXX=eg++ ./configure
4.2 Errors, missing random parts
  db4 from source, protobuf, qt, 
5. make it
  make
5.1 make throws as issue with PYTHONPATH
  use gmake as per OpenBSD 5.9 method
5.2 gmake

6. gmake check
  error: "virtual memory exhausted..."
6.1 /etc/login.conf - add memory
  for staff user set datasize=infinity (commented out other datasize lines, > 2GB should work)
6.2 gmake check (again) 
  New Error
  installed leveldb
  

Issue at step 6.2

Message from OpenBSD 5.9 guide writer:

Hello,

I am working on building Bitcoin on OpenBSD 6.0 and noticed you had written
the doc for 5.9. I am stuck with the error below when running gmake check.
I also had to bump the datasize to > 2GB in /etc/login.conf to get gmake to
run without running out of memory.

What branch / tag are you trying to build?

CXX leveldb/db/leveldb_libleveldb_a-builder.o
:0:12: warning: ISO C99 requires whitespace after the macro name
In file included from ./leveldb/port/port.h:14:0,

#define PLATFORM_IS_LITTLE_ENDIAN (__BYTE_ORDER == __LITTLE_ENDIAN)

Seems LevelDB platform is confused.
This may be a problem solved with commit 883175f in master (pull #8604)
If you're on 0.13 you couuld try to cherry-pick that one.

Built with no wallet and no gui following 5.9 steps

Will build with wallet and GUI on a fresh (and larger) vm to sync up the full blockchain tomorrow.
