make: *** [build/util.o] Error 1

When I try to make the code with make MARCHFLAGS=-march=native -f makefile I got the following error:

...

No answer?

did you solve?

@Alavi1412 these errors might be related to the version of OpenSSL you are compiling against. If i remember correctly distros such as ubuntu now have two packages for OpenSSL as there were items that were deprecated.

On Ubuntu I believe the package is openssl1.0 and openssl1.0-dev. It will likely solve your compilation issue.

I have a docker variant of this using alpine linux, might be helpful for reference or to use (I do not actively update it)

I confirm installing openssl1.0-dev and libssl1.0-dev allows to compile in Ubuntu 18.04.3 LTS
