Fwd: Linking error in FLINT when building Sage 7.4 on Ubuntu 16.10

[Dima Pasechnik]

this is IMHO ubuntu 16.10-specific (see a link further down the thread)

I'm trying to build Sage 7.4 on my laptop, now running Ubuntu 16.10. The build broke down in FLINT with what I find a rather strange linking error:

[flint-2.5.2.p0] /usr/bin/ld: -r and -pie may not be used together

The offending command is the command:

Has anyone else run into anything similar?

Yeah that is utterly bizarre. And I agree. It has to be Ubuntu 16.10 specific, assuming the configure parameters didn't contain anything odd.

Ok, so apparently gcc now uses the option -pie by default. There is a -fno-pie option you can use to turn it off, but it doesn't work. I'd send the compiler back to the manufacturer as defective.

[Bill Hart]

You can patch the gcc binary manually to fix it, apparently.
