Installing problem #258

Closed BojackFishman closed 1 month ago

BojackFishman commented 7 months ago

When I try to type "make" in the bash to compile the package, I always get some errors like:

cc: error: unrecognized command line option ‘-fcf-protection=full’; did you mean ‘-fstack-protector-all’?

I have confirmed that my gcc version is 7.5.0 , and make version is 4.3. what's the problem?

Hi Bojack,

The issue is that gcc 7.5.0 doesn't support '-fcf-protection' option: https://gcc.gnu.org/onlinedocs/gcc-7.5.0/gcc/Option-Summary.html#Option-Summary

Actually gcc 9.x supports it: https://gcc.gnu.org/onlinedocs/gcc-9.5.0/gcc/Option-Summary.html#Option-Summary

If you look at the GCC release dates you will see that in 2019 at least 2 gcc 9.x versions were released along with 7.5: https://gcc.gnu.org/develop.html#timeline:~:text=GCC%207.5%20release%20(2019%2D11%2D14)

So, the compiler version looks really outdated. I am wondering what OS do you use and if this compiler default to this OS? Is there any chance to upgrade your compiler version to a newer one?

Thanks for your reply ! Actually my OS version is Ubuntun 18.04 LTS, and yes gcc 7.5 default to it. I was misled by some inaccurate information and didn't check it carefully that I think gcc 7.5 support that option, so I was quite confused. I shall verify the information catiously in the future. Thanks again for your patient reply.

And by the way , in fact from gcc 8.4 the option '-fcf-protection' has been supported and I just have a try.
