Bug 550646 – ppc Handbook suggests invalid values for CFLAGS (-march)

• Status: RESOLVED FIXED
• Product: [OLD] Docs on www.gentoo.org

[Description Nuno Silva 2015-05-28 14:09:57 UTC]

The wiki version of the Gentoo PPC Installation Handbook suggests the GCC option -march for CFLAGS, and even has an example where -march=native is used. 

But -march is not a valid option for gcc on PowerPC. Using it results in a GCC error.

The old handbook used -mcpu and -mtune in the CFLAGS example instead, see http://web.archive.org/web/20120313110559/http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml?full=1


Reproducible: Always

GCC output when invoked with -march=native on PowerPC:

$ gcc -march=native tentti.c 
gcc: error: unrecognized command line option ‘-march=native’

That's currently part of a shared section in the handbook. I'm looking into getting it fixed, thanks for the report!

Any progress on this?

Hello! I have gone back through to old handbooks have upgraded the CFLAGS values for all the Handbooks hosted on the wiki. :)
