Hi,

I was doing an update to the system and I encountered this error of ruby-2.6.6-r2


/var/tmp/portage/dev-lang/ruby-2.6.6-r2/temp/build.log

Where can I check ?

Code:
CFLAGS="-march=nehalem -O2 -pipe -w"

What is -w option? I can reprodice the error adding this option to my cflags.

I have the same and I do not know how -w is there

Code:
CFLAGS="-march=broadwell -O2 -pipe -w"

Looking at my notes, I see that -w is to inhibit all warnings messages.

Edit: https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

Works smoothly without the -w on the CFLAGS. A bug?

Thanks!

In my case I delete -w options and could merge fine.

Perhaps -w confuses some configure test into making the wrong decision about whether to enable/disable some bit of code. It's common for configure to try to build a test program that will succeed if a property is true and fail if the property is false. Some of these rely on warnings-as-errors to get the failure they need. If you suppress all warnings, and configure does not override that, it may not get a fatal warning when it needs one, and then decide to do the wrong thing later.

Hu thanks for the possible explanation, I didn't understand how the option could break something.
