[ipxe-devel] compilation fails on openbsd

[Jiri B]

Hi,

I reported on irc but no big success.

I tried to build ipxe on OpenBSD 5.7 amd64 (recent -current snapshot)
and I used following git commit:

# since https://git.ipxe.org/ipxe.git/commit/86ae6e6c1836e43993a14db278398fc54e5419bd
# newer binutils are needed otherwise compilation fails
GH_COMMIT =     04c1ea81709b3de2658331761eb94843110c165f

So I can't use newer than 86ae6e6c1836e43993a14db278398fc54e5419bd but the
previous one fails as well :(

Help would be appreciated as I'd like to use ipxe to install securely
on an OpenStack env where I cannot trust their tftp etc...

Stuff used:
OpenBSD 5.7-current (GENERIC.MP) #903: Thu Apr  2 13:47:34 MDT 2015
ipxe 04c1ea81709b3de2658331761eb94843110c165f
binutils version 2.23.52.0.1-30.el7_1.1 20130226 (not possible to use higher version)
gcc-4.8.4p2
