gcc - Ambiguous reference to variable -

-

so doing 2 modules linking main program. first 1 has variables defined in , second 1 functions.

module1:

module zmienne  implicit none  integer, parameter :: ngauss = 8  integer, parameter :: out_unit=1000  integer, parameter :: out_unit1=1001  integer, parameter :: out_unit2=1002, out_unit3=1003  real(10), parameter :: error=0.000001  real(10):: total_calka, division,tot_old,blad  real(10),parameter:: intrange=7.0   real(10),dimension(ngauss),parameter::xx=(/-0.9602898565d0,&   -0.7966664774d0,-0.5255324099d0,-0.1834346425d0,&   0.1834346425d0,0.5255324099d0,0.7966664774d0,0.9602898565d0/)   real(10),dimension(ngauss),parameter::ww=(/0.1012285363d0,&   0.2223810345d0,0.3137066459d0,0.3626837834d0,&   0.3626837834d0,0.3137066459d0,0.2223810345d0,0.1012285363d0/)  real(10) :: r, u, r6, tempred, f, r2, r1, calka,beta  real(10) :: inte  real :: start, finish  integer:: i,j,irange  real(10),dimension(ngauss)::x,w,integrand           end module zmienne

module2

module in   implicit none   contains      real(10) function inte(y,beta,r2,r1)      real(kind=10)::r,beta,r6,r2,r1,u,y      r=(r2-r1)*y+r1      r6=(1.0/r)**6      u=beta*r6*(r6-1.0d0)      if (u>100.d0)       inte=-1.0d0       else      inte=exp(-u)-1.d0       endif      inte=r*r*inte      end function end module in

and while im calling them that:

use zmienne; use in

i getting following error:

name 'inte' @ (1) ambiguous reference 'inte' module 'zmienne'

i've deleted "inte" in module1 getting following error:

irange=inte(intrange/division)            1 error: missing actual argument argument 'beta' @ (1)

the main program code is:

 program wykres  use zmienne; use in  implicit none  open(unit=out_unit, file='wykresik.dat', action='write', status='replace')  open(unit=out_unit1, file='wykresik1.dat', action='write')  open(unit=out_unit2, file='wykresik2.dat', action='write')  open(out_unit3, file='wykresik3.dat', action='write')  ! gaussian points (xx) , weights (ww) [-1,1] interval !

the inte declared in both modules.

upd. inte(y,beta,r2,r1) function defined in module in, , used in main program. function requires 4 arguments, call 

irange=inte(intrange/division)

provides 1 argument. i'm not sure if function should used in case. try use long meaningful names variables , functions avoid similar issues.

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null
