```
git clone --recurse-submodules https://github.com/GermanAizek/mongodb-without-avx.git
cd mongo
patch -p1 SConstruct < ../no_avx_patch.diff
```
Now you need to choose a patch for your requirements.
- o2_patch.diff - default optimization
- o3_patch.diff - maximum optimization (big binary file)
- os_patch.diff - size binary optimization
Example:
```
patch -p1 SConstruct < ../o3_patch.diff
```
Done! Now we perform default building that you need.

***Note***: On memory-constrained systems, you may run into an error such as `g++: fatal error: Killed signal terminated program cc1plus`. To use less memory during building, pass the parameter `-j1` to scons. This can be incremented to `-j2`, `-j3`, and higher as appropriate to find the fastest working option on your system.
