Compile error

Hi
what reason of this error ?

LINK : fatal error LNK1181: cannot open input file ‘obj\QGCMapEngine.obj’
jom: F:\new qt\build-qgroundcontrol-qt_5_12_6-Release\Makefile [release\QGroundControl.exe] Error 1181
21:22:52: The process “C:\Qt\Tools\QtCreator\bin\jom.exe” exited with code 2.
Error while building/deploying project qgroundcontrol (kit: qt 5.12.6)
When executing step “Make”

Maybe try getting rid of directories with space in them.

Thank you . that problem was solved but another error appeared.

in simplemissionitem.cc line 1015
c2220: warning treated as error - no ‘object’ file generated
c4715: ‘simple missionitem::amslEntryAlt’ : not all control path return a value
