Re: linux and mklinuximage take 2
I have installed binutils-2.11, but the '-oformat binary' has changed to
'--oformat binary'. I editted the configure script appropriately so that the
-oformat binary test worked correctly.
However, after doing more reading on the web, I found that I may have been
better off with binutils-2.9.1. So after intalling it, and running the old
configure script, I got the following output, which is also the same output I
received with the edited configure script for binutils-2.11.
NB: config.cache deleted each time before running ./configure
..
checking assembler prefix for 32-bit addresses in .code16 mode... addr32;
checking .code16 generates native 16 bit code... yes
checking for .code16gcc assembler directive... no
configure: warning: must have .code16gcc if .code16 generates 16 bit
code--punting .code16
..
checking if ld supports -format binary... yes
checking if ld supports -oformat binary... yes
configure: warning: Cannot build Linux boot adaptor (boot/linux).
..
So it appears the problem is with .code16gcc.
Once again, any help appreciated.
cheers,
