 Hi Pavel,

there is no need for hard-float support on the target machine. The
libgcc provides all the software-emulation routines. Given that GRUB is
linked against it. Which is likely as it is a necessity when compiling
with gcc. Maybe your compilation is simply broken because of that one
missing. Could you please post the error message?

Re: Failed to configure/make under Cygwin

I've tried compiling GRUB 1.94 in Cygwin under Windows 2000, but 
"configure" fails with the following messages:


 checking whether objcopy works for absolute addresses... no
configure: error: GRUB requires a working absolute objcopy; upgrade 
your binutils


My Cygwin is up-to-date as of today, thus the 'binutils'
package has no later version available. This is the version
information I get by using the commands "ld -v" and "objcopy -V":

 GNU version 2.17.50 20060709

I also downloaded, recompiled and installed the latest version of 
'binutils', but the result did not change.
Notice that the same error is obtained while trying to "configure" the 
old, legacy GRUB version 0.97 .


Any ideas ?

Hi,

You will need a toolchain that supports i386/ELF. The Cygwin tools are
very limited and produce PE objects. Also, the binutils are either
'empty' or also tweaked for PE. There is no official toolchain for
Cygwin. In short: This won't work.
