Can't compile on ubuntu 18.04

[naren-nallapareddy]

I tried make in ubuntu 18.04, I get error

include/util_time.h:6:19: error: field ‘tic’ has incomplete type
struct timespec tic;
^~~
include/util_time.h:7:19: error: field ‘toc’ has incomplete type
struct timespec toc;

It seems I am not able to use struct timespec, I converted it into timeval and it works. Is there a reason timespec doesn't work in ubuntu?

Also I get 3 errors when I run 'make run-test'

(Test SuperSCS (0,0,1) with FPR) -- y should be nan

(Test SuperSCS (0,0,1) with R-Broyden) -- y should be nan

(Test residuals) -- rel gap [0] not NAN

I got the same error when using Ubuntu 18.04. Any suggestions? Many thanks!

Hi naren3491, did you figure out how to solve these errors?

Hi @naren3491 and @kunyuan827. Sorry for the late reply, I was out of office for a few days. This issue must be related to issue #29. You can certainly ignore the failing tests - the issue is related with the tests themselves rather that the code of SuperSCS.

I had started the branch fix/xenial, but I then had to shift my priorities, but I'll try to fix this soon.

Hi @alphaville , Thanks for your reply.

"You can certainly ignore the failing tests - the issue is related with the tests themselves rather that the code of SuperSCS." Thanks for clarifying! That helps.

Hi @alphaville , thanks for your reply. You're right. I ignored the test errors and the code works well until now.

I had the same problem with Debian 10. I could compile it with simply removing -std=c99 in scs.mk at line 53.

Can you share a working script that shows how to convert timespec into timeval? I am not very familiar with C++.
