How to compile Denarius on Ubuntu 18.04/BigNum Error/OpenSSL Version Swap

[Ghost]

Run the following commands to compile Denarius properly without errors on Ubuntu 18.04+ (Ubuntu changed their sources list for the dep "libssl-dev", you will need to install an older version of OpenSSL to be able to compile Denarius)
 

Make sure to remove the current libssl-dev:

sudo apt-get remove libssl-dev 

Install an older version of OpenSSL, for this we use 1.0.1j

wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz 

tar xvfz openssl-1.0.1j.tar.gz cd openssl-1.0.1j

cd openssl-1.0.1j

./config 

make -j(number of cores) 

That should get the older version installed.

Also you may want to symlink openssl still:

sudo mv /usr/bin/openssl /root/ sudo ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl 

openssl version

(To check the openssl version installed)

Also you will want to run these when you run qmake again

qmake "USE_UPNP=1" "USE_QRCODE=1" OPENSSL_INCLUDE_PATH=/usr/local/ssl/include OPENSSL_LIB_PATH=/usr/local/ssl/lib denarius-qt.pro 

Then you should be good for Ubuntu 18.04 Denarius compiling and it should compile with no errors , otherwise all other older Ubuntu versions you can just do the usual sudo apt-get install libssl-dev

Steps I used to get this working.

sudo apt-get install make
wget https://www.openssl.org/source/openssl-1.0.1j.tar.gz
tar -xzvf openssl-1.0.1j.tar.gz
cd openssl-1.0.1j
sudo ./config
sudo make install
sudo ln -sf /usr/local/ssl/bin/openssl `which openssl`
cd ~
openssl version -v

qmake "USE_UPNP=1" "USE_QRCODE=1" OPENSSL_INCLUDE_PATH=/usr/local/ssl/include OPENSSL_LIB_PATH=/usr/local/ssl/lib denarius-qt.pro
make

Ok i succeded at compiling the qt wallet but i cant compile the daemon it throws this:

Try this

OPENSSL_INCLUDE_PATH=/usr/local/ssl/include OPENSSL_LIB_PATH=/usr/local/ssl/lib make -f makefile.unix

this is the 2 lines I used to compile QT on Ubuntu 18.10

qmake "USE_UPNP=1" "USE_QRCODE=1" LIBS=-lboost_chrono OPENSSL_INCLUDE_PATH=/usr/local/ssl/include OPENSSL_LIB_PATH=/usr/local/ssl/lib denarius-qt.pro
