The next3 utils: <br> ~$ git clone git://</font><a href="http://github.com/amir73il/next3-utils.git" target="_blank"><font color="blue" size="3"><u>github.com/amir73il/next3-utils.git</u></font></a><font size="3"> -b next3-stable <br> <br> 2. Linux tree with next3 sources. <br> The next3-stable branch is based off stable kernel 2.6.35.9, so check it out like this: <br> ~$ git clone git://</font><a href="http://github.com/amir73il/ext4-snapshots.git" target="_blank"><font color="blue" size="3"><u>github.com/amir73il/ext4-snapshots.git</u></font></a><font size="3"> -b next3-stable ~/next3-utils/linux-2.6.35.9 <br> <br> 3. a tar ball of linux-2.6.35.9 and place it at: <br> ~/kernel/2.6.35/</font><a href="http://linux-2.6.35.9.tar.bz/" target="_blank"><font color="blue" size="3"><u>linux-2.6.35.9.tar.bz</u></font></a><font size="3"> <br> <br> Then run: <br> ~$ cd ~/next3-utils/patch <br> ~/next3-utils/patch$ make next3_snapshot <br> <br> This may take some time to unpack files from kernel tar ball and should eventually create the patch file next3_snapshot.module.patch <br> and copy it to the ~/kernel/2.6.35/ dir. <br> <br> This is the same patch that is being downloaded from the web site for all supported kernels (2.6.31-35). <br> If you copy it to ~/next3-util and run 'make module' in that directory, it should build the latest next3 version <br> for your kernel (2.6.32), which you can test by running 'sudo make test'. <br> <br> I am pretty sure I missed something in the instructions, so please let me know how far you got <br> and we'll take it from there. <br> <br> Thanks, <br> Amir. <br> <br> <br> On Fri, Apr 27, 2012 at 3:07 PM, Kim Hagen <</font><a href="mailto:kh...@mu..." target="_blank"><font color="blue" size="3"><u>kh...@mu...</u></font></a><font size="3">> wrote: </font><font face="sans-serif" size="3"><br> Hi Amir,</font><font size="3"> </font><font face="sans-serif" size="3"><br> <br> I would like a walktrough please :), and what would you advice.... use next3 or next3_ext4 (and if next3_ext4 how must i make my file-systen?)</font><font size="3"> </font><font face="sans-serif" size="3"><br> <br> Kind regards,</font><font size="3"> </font><font face="sans-serif" size="3"><br> <br> Kim</font><font size="3"> <br> <br> <br> <br> <br> </font><font face="sans-serif" size="3"><br><br></font></div></div></blockquote></div></div></div></div></div></div></div></font></blockquote></div></div></div> </div></div></font><br> <br> <br> <span style="font-family:sans-serif,helvetica; font-size:10pt; color:#000000"><br> <br> This message contains information that may be priviliged or confidential and is intended only for use by the addressee(s).<br> You are not authorized to use or distribute this message or any part of it in any form, unless you are the intended recipient.<br> If you receive this communication unintentionally or in error, please inform the sender immediately by return e-mail and delete all copies of this message.<br> <br> If you do not want to receive any e-mail from Multi Corporation and/or its affiliates in the future, please send an e-mail to: no...@mu...<br> Multi Corporation B.V., Gouda, is registered with the trade register in the Netherlands under no. 34237857.<br> <br> -------------------------------------------------------------------------------------------------------------------------------<br> <br> Dit bericht bevat informatie die vertrouwelijk kan zijn en is uitsluitend bestemd voor de geadresseerde(n).<br> Het is u niet toegestaan dit bericht of delen ervan te gebruiken of te verspreiden in welke vorm dan ook, tenzij u de beoogde ontvanger bent.<br> Indien u dit bericht abusievelijk of onterecht ontvangt, wordt u verzocht de afzender direkt te informeren door het bericht te retourneren en alle kopieen van dit bericht direkt te verwijderen. <br> <br> Indien u geen email meer wilt ontvangen van Multi Corporation of haar groepsvennootschappen kunt u dit kenbaar maken door een email te sturen naar : no...@mu...<br> Multi Corporation B.V., Gouda, staat ingeschreven in de Kamer van Koophandel onder nr. 34237857.</span> |
