This tutorial is about how to patch the executable with <code>patchelf</code> which is sufficient for most cases. If no source is available for a program patchelf is the preferred way in nixpkgs to add support for the package. | This tutorial is about how to patch the executable with <code>patchelf</code> which is sufficient for most cases.

However sometimes this is not enough, more hardcoded paths may be scattered all over the place. For this you may need to set up an FHSUserEnv, a Linux Standard Base style directory structure with a final <code>chroot</code> call to fixate all paths. For a tutorial on how to use this technique, check out [https://reflexivereflection.com/posts/2015-02-28-deb-installation-nixos.html Anders Papittos blog post on installing debian packages in nixos]. | However sometimes this is not enough, more hardcoded paths may be scattered all over the place.

We want to package a tool called "MasterPDFEditor", the package for debian can be found at [http://get.code-industry.net/public/master-pdf-editor-4.3.10_qt5.amd64.deb] ([https://web.archive.org/web/20170914112947/http://get.code-industry.net/public/master-pdf-editor-4.3.10_qt5.amd64.deb archive.org mirror]). | We want to package a tool called "MasterPDFEditor", the package for debian can be found at [http://get.code-industry.net/public/master-pdf-editor-4.3.10_qt5.amd64.deb] ([https://web.archive.org/web/20170914112947/http://get.code-industry.net/public/master-pdf-editor-4.3.10_qt5.amd64.deb archive.org mirror]). | ||
