Mac OSX 10.5.6
Matlab R2009a
gfortran/gcc
Code fragment:
subroutine mexFunction(nlhs, plhs, nrhs, prhs)
use matlabmex
implicit none
integer, intent(in) :: nlhs, nrhs
integer, intent(in), dimension(:), pointer :: prhs
integer, intent(out), dimension(:), pointer :: plhs
integer(i4b) :: l,m,n
integer(i4b), pointer :: n1
integer(i4b), pointer :: A
if(nrhs /= 2) then
call mexErrMsgTxt('Function requires four input arguments.');
end if
A = mxGetData(prhs(1))
n1 = mxGetDimensions(prhs(1))
end subroutine mexFunction
matlabmex.f90 contains:
integer (kind=4) function mxGetData(pm)
use constants
integer (kind=4) :: pm
end function mxGetData
integer (kind=4) function mxGetDimensions(pm)
use constants
integer (kind=4) :: pm
end function mxGetDimensions
integer(kind=4) function mxGetNumberOfDimensions(pm)
use constants
integer(kind=4) :: pm
end function mxGetNumberOfDimensions
in the interface block.
Compilation:
/Applications/MATLAB2009a/MATLAB_R2009a.app/bin/mex -maci mexFunction.f90
Undefined symbols:
"_mxgetdimensions_", referenced from:
_mexfunction_ in mexFunction.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
mex: link of ' "mexFunction.mexmaci"' failed.
It can find mxGetData() but not mxGetNumberOfDimensions()
I have checked my matlab documentation to confirm that the function exists.
