@aligungr

my environment: ubuntu 16.04

after I successfully installed all the

sudo apt update sudo apt upgrade

sudo apt install make sudo apt install g++ sudo apt install libsctp-dev lksctp-tools sudo apt install iproute2 sudo snap install cmake --classic

when I run 'make', got a lot of errors:

@chliny2016 gcc 9.0.0 or later is required to build UERANSIM. Maybe your gcc version < 9.

[chliny2016]

@aligungr , thanks a lot! yes, mine is gcc (Ubuntu 5.4.0-6ubuntu1~16.04.12) 5.4.0 20160609, let me upgrade it.

[ghost]

@aligungr, FYI, I have no problem building UERANSIM with gcc 7.5.0 (I use Ubuntu 18.04 and its default gcc verson is 7.5.0)

[dcrowley-Onis]

And your cmake is >3.16 ?

[dcrowley-Onis]

I've modified to use both 7.c gcc and 10.c gcc - I see the same error as the new issue I have opened. Might yet be an environment issue. Will further check
