Red Hat Bugzilla – Bug 230964
FreeBSD elf is no longer recognized, cannot compile MadWifi
Last modified: 2007-11-30 17:11:58 EST
Description of problem:
Compiling MadWifi (Linux driver for Atheros chipset) involves linking against a
closed source binary called HAL (hardware absraction layer). The binaries are
compiled for FreeBSD by a FreeBSD developer who has access to Atheros
documentation and source code. Stating a few days ago, the build is failing
because ld doesn't understand the binary:
LD [M] /home/proski/src/madwifi/ath_hal/ath_hal.o
/home/proski/src/madwifi/ath_hal/i386-elf.hal.o: file not recognized: File
format not recognized
It's not just ld. Other tools fail to understand the binary:
$ nm i386-elf.hal.o
nm: i386-elf.hal.o: File format not recognized
Exactly the same binary is recognized on Fedora Core 6:
$ nm i386-elf.hal.o |wc -l
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Download MadWifi sources:
svn co http://svn.madwifi.org/trunk madwifi
2. Try to compile it:
Build fails with the message "File format not recognized"
The kernels distributed with Fedora may have other issues, so please use "make
-k" or run make in the ath_hal directory to avoid irrelevant problems.

The problematic file, compressed with bzip2
The problem can be reproduced with binutils-220.127.116.11.12 from the binutils SRPM
without Fedora patches. However, the problem cannot be reproduced with today's
CVS version of binutils. I think binutils needs to be updated to the CVS
version. It's not like we are distributing official releases anyway.

Fixed in binutils-18.104.22.168.12-3 in rawhide.
