Hi All,

  To improve GUI performance on aarch64 server, I wanna switch 

from Gnome 3 to MATE. I have tested group of "MATE Desktop" from

yum repos of epel7, it didn't work(I amnot sure about the exact 

reason, maybe missing rpms or wrong configuration). So, I began 

to rebuild rpms from qt5(my final goal is get lightdm's rpms),  

but got same error as log in "http://buildlogs.centos.org/c7-epel.a64/".   

 Error messages like these:

 [mockbuilder@localhost origin-srpms]$ mock -r mate-5-aarch64 \

         --rebuild qt5-qtdoc-5.6.1-1.el7.src.rpm --resultdir \

         /MY-rpms/result-rpms/ --no-clean

  … …

  ERROR: Command failed: 

   # /usr/bin/yum-builddep --installroot /MY-rpms/mock/mate-5-aarch64/root/ \

     --releasever 7 /MY-rpms/mock/mate-5-aarch64/root//builddir/build/SRPMS/qt5-qtdoc-5.6.1-1.el7.centos.src.rpm

  Getting requirements for qt5-qtdoc-5.6.1-1.el7.centos.src

  --＞ qt5-qtbase-devel-5.6.1-3.el7.centos.aarch64

     Error: No Package found for qt5-qdoc

     Error: No Package found for qt5-qhelpgenerator

  I have twoo doubts，please help me to see:

  1、which rpms are qt5-qdoc and qt5-qhelpgenerator belongs to? 

  2、which srpms is base set of qt5, that should rebuild these first. Is there loop dependence when building these srpms?

  Thanks a lot!

Best Regards.
