select - Error: symbol `__fileimporter_class_MOD___copy_character_1' is already defined -


i have bit of code:

    subroutine readchartovariable(self,format,varout)     implicit none      ! declaring part     class(fileimporter) :: self     character(len=25) :: defaultvalue = 'null'     character(len=25), intent(out) :: varout     character (len=*) :: format     class(*), allocatable :: value      ! executing part     allocate(value,source = defaultvalue)     call self%readvaluetovariable(format,value)      select type(value)     type (character(*))         varout = value     end select     end subroutine readchartovariable

what is, calls readvaluetovariable value being character type. readvaluetovariable reads character file , returns in value. compiling (gcc 4.8.5) leads error

/tmp/cc5juib6.s: assembler messages: /tmp/cc5juib6.s:156: error: symbol `__fileimporter_class_mod___copy_character_1' defined

the error caused type (character(*)) line (without character functionality compiles). don't understand what's wrong here, maybe can me?

this compiler bug. related to, or directly 1 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60359, fixed in gfortran 4.9. note 4.8 not supported quite time , think release 4.9.4 last 1 4.9. supported versions 5 , 6.

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
