Subject: gcc: 0041-handle-target-sysroot-multilib.patch maybe doesn't work for n32?
Date: Tue, 13 Oct 2015 14:00:16 -0500 [thread overview]
Message-ID: <20151013140016.32f79928@seebs-worktop> (raw)
So, we have this shiny new patch which appears to correct paths for MIPS, but
when I try it with an n32 multilib, I get Very Strange failures.
The actual failing line, from gcc -v:
/msp-lpggp22/seebs/oemips/sysroots/x86_64-oesdk-linux/usr/libexec/mips64-oe-linux/gcc/mips64-oe-linux/5.2.0/collect2

[... and many more errors related to this
So, looking around, I see three crtbegin.o in the sysroot:
/usr/lib/mips-oe-linux/5.2.0/crtbegin.o
/usr/lib64/mips64-oemllib64-linux/5.2.0/crtbegin.o
/usr/lib32/mips64-oemllibn32-linux-gnun32/5.2.0/crtbegin.o
And presumably, I want the gnun32 library. But what it actually picked was:
/usr/lib64/../lib32/mips64-oe-linux/5.2.0/32/crtbegin.o
And that's the 32-bit (base library) crtbegin.o.
I am pretty sure that the gcc patch 0041 affects this but I honestly don't
entirely understand it.

Listen, get this. Nobody with a good compiler needs to be justified.
