Problems in the very first Building phase : third_party/cares/cares/ares_init.c:301:17: error

[Marco Ippolito]

Hi,

I 'm my Ubuntu 18.04.1 LTS I'm just trying to install and build gRPC, but in the "make" step there, as you can see, there is an error:

third_party/cares/cares/ares_init.c: In function ‘ares_dup’:
third_party/cares/cares/ares_init.c:301:17: error: argument to ‘sizeof’ in ‘strncpy’ call is the same expression as the source; did you mean to use the size of the destination? [-Werror=sizeof-pointer-memaccess]
           sizeof(src->local_dev_name));

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

What do I have to do to solve the problem? Looking forward to your kind hints and help.

Not sure if it is the case here, but sometimes a previous version of gRPC installed in your system would cause build issue. That might apply to your situation...

[xya...@gmail.com]

Were you able to resole this issue?

[jreub...@gmail.com]

I've encountered the same problem

[2can]

I was able to build using stable debian:stretch. The problem still persists in debian:testing

The warning comes from c-ares where they are using src->local_dev_name , which is an array, with sizeof() and strncpy.
