Cmake exit

[SimonRastikian]

Hello,

After the last chat, I updated my OS to Ubuntu 20.04. Now :

• gcc version is 9.3.0
• cmake version 3.20.0
• docker version 19.03.8, build afacb8b7f0
• cargo version 1.51.0 (43b129a20 2021-03-16)
  Things should be up to date however there is still a build problem. This is what the terminal outputs :

Compiling ... (all packages) then there is
Compiling oqs-sys v0.1.0 (/home/simonpc/Documents/kemtls-experiment/oqs-rs/oqs-sys)
error: failed to run custom build command for oqs-sys v0.1.0 (/home/simonpc/Documents/kemtls-experiment/oqs-rs/oqs-sys)

error: build failed

I checked the CMakeOutput.log file and it is said
The system is: Linux - 5.8.0-48-generic - x86_64

Do you know what should I be doing to solve this?

• CMake is complaining about lack of make, so you probably want to run apt-get install build-essential.
• The remainder seem warnings that can safely be ignored.

Thank you a lot Thom! After I ran this I discovered I also had clang missing. As you said I did not pay attention to all the declared but unused functions warnings however some new warning of the type

is occurring,
however things seem to work and the target/debug/examples/tlsserver --help indeed outputs a help manual.

Thank you again!

Yeah, such things happen if you're using Rust — the repo should really be pinned to a particular version of the compiler. Good to hear that it's mostly fixed.
