Related development of domestic Kirin system

problem

   When the Kirin application is deployed to the target hardware, a problem appears "undefined symbol: __cxa_throw_bad_array_new_length, version Qt_5".
   The error screenshot is as follows ：
  

Work done in advance

  1. Use the virtual machine to install Kirin for testing in advance Qt, Several physical machines were used in advance to test Qt No problem .

Try to solve

  1. take Qt The version is changed to Qt edition , The same goes for running （ As long as the machine where the application is deployed is not installed Qt）, Even if it's installed Qt If installed Qt If the path of is different from that of the development machine, an error is also reported .
  2. Will be installed Qt Several libraries of version ,cp To /lib/x86…( The system is placed in the path of the runtime ） Replace several Qt library , The Kirin interface is down .
  3. Use QCustomplot( Use opengl, Installed opengl）, The operation reports the same error .
  4. Use QCustomplot( not used opengl, Shut down the opengl）, The operation reports the same error .
  5. No QCustomplot, Operation can display （ Command line run ）.

Cause analysis

  1. Analyze according to the solution , And opengl irrelevant , But with the QCustomplot Control related .
  2.Qt5.12.8 The library is exactly the same , But will Qt Copy the library to the system directory （ only QWidgets library ） It caused the kylin desktop to collapse , You can basically judge that Kirin compiled it by itself Qt5.12.8 The library of .
  3. End use LD_LIBRARY_PATH You can take QCustomplot The running error is eliminated ,

resolvent

   This error uses LD_LIBRARY_PATH= install Qt In the directory of gcc_64/lib, The error can be eliminated , And run .
