Can't Build Msieve on fedora

Gokuruto · 2018-05-20, 22:10

Hi,
I have a problem with building Msieve on fedora.
I have downloaded sources and then tried to build then with "make all"
but i get this piece of warning and it doesn't build.

demo.c: In function ‘main’:
demo.c:448:13: warning: this statement may fall through [-Wimplicit-fallthrough=]
flags |= MSIEVE_FLAG_NFS_LA_RESTART;
~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
demo.c:449:6: note: here
case '2': /* fall through */
^~~~
demo.c:545:5: warning: ‘strncpy’ specified bound 500 equals destination size [-Wstringop-truncation]
strncpy(buf, argv[i], sizeof(buf));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Does latter-day gcc treat warnings as errors? There would have to be something else going on, as these would not be fatal under ordinary circumstances.

Maybe somewhere -Werror is passed? Did you try it with -Wno-error to get past the warnings?
