And I made the test on ubuntu 16.04 this time. All I had to install was:
sudo apt-get install gcc-multilib g++-multilib
sudo apt-get install lib32z1-dev

I confirm that this works even on lubuntu 17.10 for CONSOLE appliccation.

However for GUI program it is not enough. Other libraries in :i386 version need to be installed.
At moment I was not able to install everything. The Xft lib in 32 bit mode cannot stay with the one in 64 bit (apt-get want to remove one to accomodate the other). So I preferred to not spoil the 64 bit system. Maybe exist some way to install what is necessery.

edit: today I have installed libxft-dev:i386 . The installation removed the libxft-dev at 64 bit. However I was able to compile a 32 bit application.
Then I tried to compile the 64 bit application. Obviously the compiler complained the missing libxft-dev. I tried to install it but it removed the 32 bit version! A nightmare.
It seems libxft-dev cannot coexist in the same machine in 32 and 64 bit mode. This prevent to compile easily a program in 32 and 64 bit... at least on lubuntu
