            Bug ID: 28545
           Summary: cross compile incorrectly using host libraries in
                    install relink
           Product: binutils
           Version: 2.37
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libctf
          Assignee: unassigned at sourceware dot org
          Reporter: bugs.sourceware at johnthomson dot fastmail.com.au
  Target Milestone: ---

I am trying to cross compile an arm OpenWrt target on an x86_64 Arch Linux host
(host Arch Linux binutils package 2.36.1-3).
This worked without issue before OpenWrt switched to binutils 2.37

The issue is seen in install, relink, (cross) compiling openwrt's
package/devel/binutils:
/usr/lib/libiberty.a: error adding symbols: file format not recognized

The issue I am seeing looked very similar to
https://sourceware.org/bugzilla/show_bug.cgi?id=27360
With that fix applied to both the OpenWrt toolchain, and package binutils, 2.37
moves past the above error, and gives this one:

/usr/lib/libz.so: file not recognized: file format not recognized

Is it possible that zlib needs the same kind of fix?

OpenWrt does make some slight patches to binutils:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=toolchain/binutils/patches/2.37;h=0b79f8ca1a95eb53cf16d70e4229c90639cb2448;hb=HEAD

Cheers
