error: use of undeclared identifier 'mean'

[ankane]

Specifications

• OS: Mac 12.1
• SCS Version: 3.1.0
• Compiler: Apple clang version 13.0.0 (clang-1300.0.29.30)

Description

Compilation fails with SCS 3.1.0 and USE_LAPACK=0 with error: use of undeclared identifier 'mean'. Changing line 88 to scs_float mean = 0.0; fixes it.

How to reproduce

make USE_LAPACK=0
