 +=== Download the components === 
 + 
 +Typically there are a minimum of three assets to download: 
 + 
 +  - The SlackBuilds.org build recipe archive. 
 +  - The build recipe archive's GPG signature 
 +  - The source archive of the software application 
 + 
 +== Download the SlackBuilds.org recipe archive == 
 + 
 +Right click on the URLs for the SlackBuilds.org recipe archive: 
 + 
 + 
 +{{:slackwarearm:arm-sbo-rightclick-recipe-url.png?400|}} 
 + 
 +Use ''wget'' to download the assets.  
 + 
 +Type ''wget'' and paste the URL into the shell/terminal window 
 + 
 +<code> 
 +wget https://slackbuilds.org/slackbuilds/15.0/system/p7zip.tar.gz 
 +</code> 
 + 
 +== Download the SlackBuilds.org recipe archive digital signature == 
 + 
 +Right click on the URL for the SlackBuilds.org recipe archive digital signature. 
 +Type ''wget'' and paste the URL into the shell/terminal window: 
 + 
 +{{:slackwarearm:arm-sbo-recipe-gpgsig.png?400|}} 
 + 
 +<code> 
 +wget https://slackbuilds.org/slackbuilds/15.0/system/p7zip.tar.gz.asc</code> 
 + 
 +=== Verify the SlackBuilds.org recipe archive === 
 + 
 +<code> 
 +gpg --verify p7zip.tar.gz.asc 
 +gpg: assuming signed data in `p7zip.tar.gz' 
 +gpg: Signature made Sat 28 Jan 2023 01:30:52 AM GMT using DSA key ID 9C7BA3B6 
 +gpg: Good signature from "SlackBuilds.org Development Team <slackbuilds-devel@slackbuilds.org>" 
 +gpg: WARNING: This key is not certified with a trusted signature! 
 +gpg:          There is no indication that the signature belongs to the owner. 
 +Primary key fingerprint: D307 6BC3 E783 EE74 7F09  B8B7 0368 EF57 9C7B A3B6 
 +</code> 
 + 
 +You should see ''Good signature from "SlackBuilds.org'' 
 + 
 + 
 +=== Unpack the SlackBuilds recipe archive === 
 + 
 +<code> 
 +tar xf p7zip.tar.gz 
 +cd p7zip 
 +</code> 
 + 
 +=== Download the software's source archive === 
 + 
 +Right-click the URL of the software's source archive: 
 + 
 +{{:slackwarearm:arm-sbo-src-url.png?400|}} 
 + 
 +Use ''wget'' again to download it: 
 + 
 +<code> 
 +wget https://github.com/p7zip-project/p7zip/archive/v17.04/p7zip-17.04.tar.gz 
 +</code> 
 + 
 + 
 +=== Verify the integrity of the source archive === 
 + 
 +MD5 sums are displayed on the SlackBuilds page for the software archives: 
 + 
 +{{:slackwarearm:arm-sbo-src-md5sum.png?400|}} 
 + 
 +You need to compare this to the version you have downloaded and ensure they match. 
 + 
 +<code> 
 +openssl md5 p7zip-17.04.tar.gz 
 +MD5(p7zip-17.04.tar.gz)= 00acfd6be87848231722d2d53f89e4a5 
 +</code> 
 + 
 +You can either compare this visually or use a command to do it. 
 +You can copy and paste the md5sum from the web page into the shell: 
 + 
 +<code> 
 +[ "$( openssl md5 p7zip-17.04.tar.gz | awk '{print $2}' )" = "00acfd6be87848231722d2d53f89e4a5" ] && echo good 
 +good 
 +</code> 
 + 
 +=== Adjust the SlackBuild build recipe for AArch64 === 
 + 
 +An [[https://git.slackbuilds.org/templates/commit/?id=20ac57b04874a38a4a1b4aa8d0fa4ec95a5605a4|update to the SlackBuilds templates]] was made for new additions to 
 +the SlackBuilds.org repository, but at present (April 2023) most/all packages will require minor changes to handle Slackware AArch64. 
 + 
 +Fortunately in 99% of the cases we can use a single command to fix them up.  Paste in the following command: 
 + 
 +<code> 
 +sed -i '/^elif \[ "\$ARCH" = "x86_64" \]; then$/ s/x86_64/aarch64/' p7zip.SlackBuild 
 +</code> 
 + 
 +=== Build the package === 
 + 
 +<code> 
 +./p7zip.SlackBuild 
 +</code> 
 + 
 +If the package builds successfully it will be stored in ''/tmp'': 
 + 
 +{{:slackwarearm:arm-sbo-pkgbuilt.png?400|}} 
 + 
 +== Build failures due to compiler flags == 
 + 
 +In some cases the use of the ''-fPIC'' compiler flag may cause a build to fail.  In such cases the compiler will inform you of this directly, and you must remove it.   
 + 
 +Open the ''p7zip.SlackBuild'' in your favourite text editor. 
 + 
 +Locate the following section: 
 + 
 +{{:slackwarearm:arm-sbo-standardflags.png?400|}} 
 + 
 + 
 +Remove ''-fPIC'' from the ''SLKCFLAGS'' variable so that it looks like this: 
 + 
 +{{:slackwarearm:arm-sbo-removedfpic.png?400|}} 
 + 
 +Save the edited build script and re-build. 
 + 
 +== Build failures due to other reasons == 
 + 
 +The vast majority of the SlackBuilds.org package maintainers do not test their packages on ARM, and so some packages may fail to build. 
 +In such cases if you're able to fix it yourself, you should do so and submit the fix to the maintainer. 
 + 
 +If you are unable to resolve it, you can post to the [[https://www.linuxquestions.org/questions/slackware-arm-108/|Slackware ARM forum on LinuxQuestions]] for help. 
 + 
 + 
 +=== Install the package === 
 + 
 +<code>installpkg /tmp/p7zip-17.04-aarch64-1_SBo.tgz</code> 
 + 
 + 
 + 
 + 
 +
