[ipxe-devel] [gPXE] gPXE help

[Jonathan Smith]

Hi,

I am upgrading to iPXE with a view to using scripting.

I have downloaded iPXE and am trying to build it by using 'cd ipxe/src' and 'make', as per the instructions on the website.
However, when I do this I get the following errors (I have only included the first few lines):

[DEPS] arch/i386/prefix/unnrv2b16.S
[DEPS] arch/i386/prefix/unnrv2b16.S
[BUILD] bin/unnrv2b16.o
arch/i386/prefix/unnrv2b16.S:9:21: error: unnrv2b.S: No such file or directory

bin/blib.a(libprefix.o): In function `prot_call_vector':(.data16+0x4): undefined reference to `prot_call'

I have checked and the arch/i386/prefix/unnrv2b16.S file exists. I have also checked that gcc, binutils, make and perl are installed. I am using Gentoo linux.

Any help you can give would be much appreciated.

Jonathan

Upgrade to iPXE (http://ipxe.org) and use the "reboot" command in an embedded 
script:

  http://ipxe.org/cmd/reboot
