hi

Due to my poor compile skills on TC....I built grub2 on a debian system following the wiki here
http://wiki.tinycorelinux.com/Creating+Extensions

The trouble is....I can't see any mention of CXXFLAGS even though I set it before running the configure file.

I know its a long bow for someone to trouble shoot....but as I lack the skills maybe someone can spot where I went wrong?

If interested here are the 2 files that might be of interest?

http://stashbox.org/922963/g2-config.txt

and the Makefile missing flags

http://stashbox.org/931638/Makefile

Questions if I may?

1) do I need cxxflags set for the devs to accept a package build on a non-TC distro?

2) Do some distros not use CXXFLAGS?

3) or is there some other reason why I can't spot this flag?

thanks for reading

PS.....my tcz installs just fine.....I am just trying to get it ready for submission status

Bits taken from both files look reasonable to me....but I don't count heh heh

Code: [Select]

 $ ./configure --prefix=/usr/local


Configured with: ../src/configure -v --with-pkgversion='Debian 4.4.4-2' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs

why don't you build it in TC ? there is everything you need to build anything

for your main question does grub2 even have a c++ code ? if so there is no need to CXXFLAGS

I'm also surprised why one would bother with "foreign" compilation. Apart from the question whether an extension created that way is acceptable for the wider public I imagine all sorts of headaches with library version etc.

As I have done for some private tests my own build of GRUB2 I'm attaching the build script I've used for that purpose. Since I did not quite get around to make use of it until now I have to state that the result has only received some fairly light testing. Nevertheless it might be useful for what you are trying to do.

Because I lacked the skills.

Yes I agree there would be reservations about accepting a tcz based on a different distro.....thats why I posted.

It does not explain why I could not compile when maro can and did.

who cares now?

maro

Thankyou very much for your script.

Forgive any rudeness....not intended....but I have just run scipt and it creates 2 tcz files...grub2 and the locale.....the doc will be ignored as the wiki will suffice.

I will honour your intentions and keep them separate.
I also will add in my grub.cfg

and still stubbornly persist with a grub2 font file....but that was built on TC.

To anyone interested.

I have designed grub2 to use an absolute config file just like grub-legacy.

Smarter people like maro can probably tell my I am doing it all wrong......grins sheepishly.

but hey....I look like an idiot because I have drunk too much aussie beer.
Steinlager is also quaffable but I digress.

Until that brilliant script came along.....I was almost at testing my build instructions. Now I can slink away and start afresh

Thankyou all

unpublished wiki is here...
http://wiki.tinycorelinux.com/gfx


feel free to tell me more harsh truths....grins again

regards

gordy

oops I spoke too soon.

ok here was my "defining" test.....in VirtualBox......IMHO

1) boot live cd...mount partition and wipe contents of boot/grub which was setup with grub-legacy hard drive persistence is sda1

install with my debian tcz version of grub2.tcz....and use a really basic grub.cfg using vi

menuentry {
linux /boot/bzImage tce=sda1
initrd /boot/tinycore.gz
}

Before reboot....check contents of boot/grub looks good

it boots

2) while still in booted hard drive mode....wipe boot/grub contents

install "build" grub2.tcz and use same grub.cfg  above

Before reboot....check contents of boot/grub looks good.......it looks exactly the same....although I did not count each file at this stage.

it fails to boot....dropping me into grub rescue ....error disk not found
(not the normal.mod but the disk or drive)

3) Re-looking at INSTALL file at source for grub2 it states

"* GCC 4.1.3 or later
* GNU Make
* GNU Bison 2.3 or later
* GNU gettext 0.17 or later
* GNU binutils 2.9.1.0.23 or later
* Other standard GNU/Unix tools"

I am wondering if the error lies with not using gcc 4.4.0  or with binutils 2.19.1?

any feedback would be greatly appreciated.

PS I get no errors on using the same command for MBR install which was
grub-install --no-floppy --root-directory=/mnt/sda1 /dev/sda

4) If any kind soul has the time to suggest how to modify the build script ....if that is all it takes....please help

It's not certain, but if this was the issue, I would have thought you'd get an error at compile time.

HI

I have decided to build the lot using dpkg-deb as I kinda know what I am doing where as I have no idea how to check build scripts.

It also means that I can maintain my own package which is morally acceptable ....heh heh instead of relying on others.

Of course the devs can still refuse my packages as its a free world.
