### OpenSSL
OpenBSD uses a replacement of OpenSSL: LibreSSL. This can cause compatibility issues, hence `./configure` will bark if you try to compile with this library:
Detected LibreSSL: This is NOT supported, and may break consensus compatibility!
To install a 'real' OpenSSL use:
pkg_add openssl
Any program linked against this library can only be used after setting the dynamic library path:
export LD_LIBRARY_PATH="/usr/local/lib/eopenssl"
(otherwise there will be an error about not being able to find `libcrypto.so.1.0`)
Alternatively, pass `--with-libressl` to `./configure`, however as the warning says, this is NOT supported, and may cause problems syncing the chain, or the node to fork off the network in unexpected circumstances.
### Building BerkeleyDB
BerkeleyDB is only necessary for the wallet functionality. To skip this, pass `--disable-wallet` to `./configure`.

Make sure `BDB_PREFIX` and `BOOST_PREFIX` are set to the appropriate paths from the above steps.
To configure with wallet:
```bash
./configure --with-gui=no --with-boost=$BOOST_PREFIX \
CC=egcc CXX=eg++ CPP=ecpp \
SSL_CFLAGS="-I/usr/local/include/eopenssl" SSL_LIBS="-L/usr/local/lib/eopenssl -lssl" \

LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/"
```
To configure without wallet:
```bash
./configure --disable-wallet --with-gui=no --with-boost=$BOOST_PREFIX \
CC=egcc CXX=eg++ CPP=ecpp \
SSL_CFLAGS="-I/usr/local/include/eopenssl" SSL_LIBS="-L/usr/local/lib/eopenssl -lssl" \
CRYPTO_CFLAGS="-I/usr/local/include/eopenssl" CRYPTO_LIBS="-L/usr/local/lib/eopenssl -lcrypto"
CC=egcc CXX=eg++ CPP=ecpp
```
Build and run the tests:
```bash
gmake
export LD_LIBRARY_PATH="/usr/local/lib/eopenssl"
gmake check
```
