Hi, @StefanJum, I added a README.md file and forced push. I don't know about the patches/ directory. I will let @Ioana-Stancioiu answer that.

Hi, @StefanJum and @razvand, I originally compiled and tested the code on an older version of Unikraft, the one present on the run-app-elfloader master branch. The lookup.patch file solves a problem that I experienced while running ispell on this version. The number of bytes read on line 7 did not match the specified number. I discovered that reading the hashstring in a while solved the error. The ispellh.patch and term.patch files solve a symbol has multiple definitions linking error, BC variable is defined in the termcap library as well, from what I remember. Without these patches I was unable to compile the binary locally, on Ubuntu 20.04. As @StefanJum suggested I tried testing the binary with the Lyon Hackathon setup with no success. I would be grateful if you could try testing this as well, the patches might prove to be unnecessary.

Got it @Ioana-Stancioiu. I tested it using run-elfloader and it works fine, great work.

@Ioana-Stancioiu, @StefanJum, I confirm. It also works on my end: running on top of Unikraft in binary compatibility mode.
