I am interested in your work as well. I ported Qt 5.9 to a NXP LPC3250 last year. I updated RTEMS LIBBSD to support EVDEV and added to the RTEMS MMAP interface to support MMAP handlers in frame buffer drivers. I was successful in getting the QT Quick clock demo application to run on RTEMS using the LinuxFB plugin. I would be interested to see how you created your RTEMS plugin.

And it looks to be great work! Thank you for the complimentary things you said about RTEMS features. I have a few questions. + Is this going to show up in the Qt free edition? + Any ideas on what RTEMS could do to improve our side of the hosting Qt equation? Graphics has always been a challenge. FWIW I took a stab at estimating porting Qt a few years ago. It is a large body of software and a lot is just not appropriate for most embedded devices. I got a reasonable subset to build but never got funding to do the actual work. I am quite thrilled your effort was more successful.

However, I learned that Qt Applications works with X11 libraries in systems like Rtems. And I have to compile the nxlib library for raspberrypi BSP in the rtems-graphical-toolkit for X11. 'graphics\nxlib.bset' in rsb can not be build as mentioned in "https://lists.rtems.org/pipermail/devel/2015-August/012358.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.rtems.org_pipermail_devel_2015-2DAugust_012358.html&d=DwMFaQ&c=2do6VJGs3LvEOe4OFFM1bA&r=dbavT-WIJ4nBfQFKYnKdAD52Vyq3ZXSzrL9TAm21lZI&m=2qOzfS7qOLo1pWDBn2daTfb11BT4SII6DAGj7Nybgz0&s=FP3leA0B8WdfvIUwiGG0f2VRmehMyQCINAcYMEOWL8k&e=>". I understand that the nxlib is included in microwindows library anymore, but when I build 'graphics/microwindows.bset', will I also build nxlib?. BSP 's X11 header files and so on. How do I add X11 header files to BSP and other necessary files? What should I do at this point?

Can you give me some advice? A change went into the RSB in October last year to stop using the MD5 and SHA1 checksums as they are insecure. The ticket that covered this issue is: https://devel.rtems.org/ticket/2536<https://urldefense.proofpoint.com/v2/url?u=https-3A__devel.rtems.org_ticket_2536&d=DwMFaQ&c=2do6VJGs3LvEOe4OFFM1bA&r=dbavT-WIJ4nBfQFKYnKdAD52Vyq3ZXSzrL9TAm21lZI&m=2qOzfS7qOLo1pWDBn2daTfb11BT4SII6DAGj7Nybgz0&s=W5nqzhQZQ8MD2Qny_KmidQ3uYRpLeCKJeVIEUl3iORE&e=> It would seem some packages were missed and they need a better checksum. Could you please reopen the ticket and indicate the issue you have by pasting in the above output? FYI the fix is easy, run a sha512 command on your host on the file or patch which should be in the `sources` or `patches` directory and then update the line in the related file. The freetype config file is: rtems/config/graphics/freetype-2.4.10-1.cfg On the line starting with `%hash` change `md5` to `sha512` and paste in the SHA512 checksum. I see ... libjpeg-9a-1.cfg libpng-1.5.24-1.cfg libpng-1.6.21-1.cfg libtiff-4.0.2-1.cfg libtiff-4.0.6-1.cfg microwindows-0.93-dev-1.cfg t1lib-5.1.2-1.cfg ... are still using MD5 and will need updating. We welcome patches, it is often the fastest way to get something like this fixed. :) Thanks Chris _______________________________________________ users mailing list users@rtems.org<mailto:users@rtems.org> http://lists.rtems.org/mailman/listinfo/users<https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.rtems.org_mailman_listinfo_users&d=DwMFaQ&c=2do6VJGs3LvEOe4OFFM1bA&r=dbavT-WIJ4nBfQFKYnKdAD52Vyq3ZXSzrL9TAm21lZI&m=3l9d5ztgZL8IrTHvJLI4-LwXD6K3_k4zrzE8gCCTKBg&s=GvLnp4QsFLEnTgp-tcu5NsRIPM5VycdbAjJQFCY4cJ0&e=> _______________________________________________ users mailing list users@rtems.org<mailto:users@rtems.org> http://lists.rtems.org/mailman/listinfo/users<https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.rtems.org_mailman_listinfo_users&d=DwMFaQ&c=2do6VJGs3LvEOe4OFFM1bA&r=dbavT-WIJ4nBfQFKYnKdAD52Vyq3ZXSzrL9TAm21lZI&m=3l9d5ztgZL8IrTHvJLI4-LwXD6K3_k4zrzE8gCCTKBg&s=GvLnp4QsFLEnTgp-tcu5NsRIPM5VycdbAjJQFCY4cJ0&e=>
