<p class="MsoNormal">Thank you for your help Chris, I did what you said and it worked. 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 "<a href="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=" target="_blank">https://lists.rtems.org/pipermail/devel/2015-August/012358.html</a>".
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? <o:p></o:p></p>

This sounds like an interesting project.<br>

<br>
A change went into the RSB in October last year to stop using the MD5 and SHA1<br>
checksums as they are insecure. The ticket that covered this issue is:<br>
<br>
<a href="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=" target="_blank">https://devel.rtems.org/ticket/2536</a><br>
<br>
It would seem some packages were missed and they need a better checksum. Could<br>
you please reopen the ticket and indicate the issue you have by pasting in the<br>
above output?<br>
<br>
FYI the fix is easy, run a sha512 command on your host on the file or patch<br>
which should be in the `sources` or `patches` directory and then update the line<br>
in the related file. The freetype config file is:<br>
<br>
rtems/config/graphics/freetype-2.4.10-1.cfg<br>
<br>
On the line starting with `%hash` change `md5` to `sha512` and paste in the<br>
SHA512 checksum.<br>
<br>
I see ...<br>
<br>
libjpeg-9a-1.cfg<br>
libpng-1.5.24-1.cfg<br>
libpng-1.6.21-1.cfg<br>
libtiff-4.0.2-1.cfg<br>
libtiff-4.0.6-1.cfg<br>
microwindows-0.93-dev-1.cfg<br>
t1lib-5.1.2-1.cfg<br>
<br>
... are still using MD5 and will need updating.<br>
<br>
We welcome patches, it is often the fastest way to get something like this fixed. :)<br>
<br>
Thanks<br>
