GRUB2 build errors running slackware64-current (slackware 14)


Trying to build GRUB2 on slackware-current. I had this machine running on a basic slackware64 13.37 install and I liked booting with GRUB. Dumped everything and loaded up -current. Everything seems to work except when trying to build the GRUB2 package it errors out with the following:

1.99 doesn't build on -current, try building 2.00: these are the modifications I have made here to the slackbuilds.org script

Thanks for this - I now have grub2 installed.

Just a quick question - I made a patch file. Will it have been processed automatically during the build process or do I need to run it separately?

Thanks in advance

as you can see in the modifications I have made in the link above to the slackbuilds.org's script for building grub2, usually patches apply before the package compiling process, just after the source tarball extraction, so that the building phase runs on the patched sources.

great, thanks. I'll reverse the installation of grub2. I've not used a patch file before.

This is a really dumb question now I've done it wrong - do I patch the grub-2.00.tar.xz?

Thanks

sorry, but I can't understand what you want to do.
can you describe what you patched and for doing what?

In the link above you provide some amendments to the grub2.SlackBuild and other files.

To cut a long story short, I don't know what to do with this bit of code. I was thinking that I make a .patch file that I then need to apply to a file. Sorry if I seem obtuse, I've just not encountered this before.

Code:
diff --git a/system/grub2/initrd_naming.patch b/system/grub2/initrd_naming.patch
new file mode 100644

no prob

that is a git commit in my repository, in which I'm modifying some files of the grub2 build script hosted on slackbuilds.org.
you can download the tarball from slackbuilds.org, extract it, enter the grub2 folder and then apply the patch of the whole commit (the link "patch" on the "commit" line)
Code:
patch -p1 < ../7eef5365a40c3c8bc39c092947baae6b432cbfad.patch
you can alternatively navigate in the tree (the link "tree" in the upper part of the page) and download the single already modified files (the link "plain" on the same line of the files).

then you can launch the slackbuild to build grub2 (assumed you have installed before all the dependencies listed in its README and downloaded the sources of grub2 in the same folder), the additional initrd_naming.patch file (that you can see in its patch form above: that is a patch that create itself another patch, the file initrd_naming.patch) is applied automatically during the build by the patched grub2.Slackbuild, that has these lines added inside
Code:
# We use initrd.gz here, so look for it too
patch -p1 < $CWD/initrd_naming.patch
for general usage of the slackbuild.org's scripts, have a look at the howto.

Thanks! I'd got that all messed up!

Appreciate the clarification, all done.

Thanks again!

slackbuild for kernel 2.3.4 with xen options

Hi all,

I need the package of kernel with below options:

"Processor type and features" -> "High Memory Support" -> Make sure it is set to 64GB
"Processor type and features" -> "PAE (Physical Address Extension) Support" -> enable
"Processor type and features" -> "Paravirtualized guest support" -> enable
"Processor type and features" -> "Paravirtualized guest support" -> "Xen guest support" -> enable
"Device Drivers" -> "Block devices" -> "Xen virtual block device support" -> enable either as a module or built in
"Device Drivers" -> "Network device support" -> "Xen network device frontend driver" -> enable either as a module or built in


The below package is not boot on Xen I mean Amazon aws...
