Re: [edk2-buildtools] x86_64 GccShellPkg

Rajitha,

Hi.  Can you explain what you'd like to do?

If you'd like to run a EFI simulation under Linux, then you would need to
build UnixPkg, but you should know that it does not support x86-64 (X64).
UnixPkg can only be built with the ELFGCC toolchain.  The ELFGCC toolchain
only supports IA32, and it only supports building the UnixPkg.  It may be
possible to build UnixPkg as a 32-bit application under Linux x86-64, but I
don't know if this has been done previously.

If you'd like to run an EFI environment under Linux, you might take a look
at the OVMF project:
http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=OVMF
This project runs under the QEMU virtual machine.

Perhaps you'd like to build the GccShellPkg?  This is a port of the ShellPkg
(EFI shell + apps) to make it build with GCC.  If this is what you'd like to
do, then you should try to use either the UNIXGCC of GCC44 toolchains.
