--- Comment #4 from Phil <phd...@gmail.com> --- Dear KDE "K3b" developers and maintainers, Leslie Zhai, Sebastian Trueg, Thomas Schmitt, 1. To all of you, Thank you for working on this great K3b application, and making it even better. 2. It looks like you are using "QT" development for some if not all of this? I do not yet know enough about "QT" to help with that. Although, the link from Thomas regarding the use of "QCryptographicHash::Sha256" (and its variations) look pretty good too me. I don't know if this will help or not, but when I use Linux Mint for evaluating checksum values, I can use the commands below. As far as I know, all Linux distros (and maybe MS Windows too) have the command "sha256sum" already installed. To get the checksum value: Example: sha256sum -b linuxmint-18-kde-32bit.iso Results in: ff8bacc631e7955fc6b0f86c9014ce27aa455e3ee0913de0b2bc6c366b63c693 *linuxmint-18-kde-32bit.iso To verify a checksum of a file with its downloaded checksum file (sha256sum.txt) in the same folder, I can use either of these console terminal commands: Example: sha256sum --check sha256sum.txt or sha256sum --check --ignore-missing sha256sum.txt Results in: linuxmint-18-cinnamon-32bit.iso: OK linuxmint-18-kde-32bit.iso: OK linuxmint-18-mate-32bit.iso: OK linuxmint-18-xfce-32bit.iso: OK 3.) I tried to compile "K3b" from the link below using the "install.txt" instructions, and could not successfully compile it on my Linux Mint KDE 32-bit system. Unfortunately, I only have an ancient 32- bit computer (11+ years old Pentium 4 computer (single core)) which cannot install any version of QT higher than "Qt v5.5" and 32-bit. So, I still need alternate compiling instructions (easy detailed ones please), or I would prefer easy to install ".deb" files, or a PPA. https://github.com/KDE/k3b Best regards to all of you and yours, Phil -- You are receiving this mail because: You are watching all bug changes.
