Can I build EOSIO with less than 7GB of RAM? | Answer: Yes

Question

System Requirements (all platforms)

7GB RAM free required
20GB Disk free required

I was going to ask this question because I didn't see it on here, but I actually wound up figuring it out myself, so I thought I would share. You can actually edit any of the build shell scripts to a lower RAM limit. I'm using an old Mac with 4GB of RAM.

Answer 1

Minimum requirements:

4GB RAM 
2 cores

The auto build script (./eosio_build.sh) capures your OS and selects the build script in ~/eos/scripts/ for your OS. You can nano your OS's build shell and perform the change in the photos below.

cd ~/eos/scripts    
sudo nano eosio_build_ubuntu.sh

Mac:

Fedora

Amazon

Centos

I got the photos from this Github issue

If you get the error "Mac OS 10.13.3 build error "path mongo-cxx-driver already exists" do:

sudo rm -rf /tmp/mongo*
cd /path/to/eos
rm -rf build/
git pull
git submodule update --init --recursive
./eosio_build.sh
