KNOWN PROBLEMS WITH INSTALLING SUITESPARSE AND SOLUTIONS TO THEM

  There are some problems with installing SuiteSparse for  64bit Linux,
  Matlab 7.8 (or newer). The problem can be fixed as follows


  - Compiling SuiteSparse seems to finish allright. However, when running
    demos you will end up in segmentation fault. 
  - The problem occurs with CHOLMOD, UMFPACK, and SPQR packages and can
    be prevented with the following steps:
 
  * Open file SuiteSparse/CHOLMOD/MATLAB/cholmod_make.m
  * Go to the line 46
  * Replace the following lines 

    (46) if (~isempty (strfind (computer, '64')))
    (47)     % 64-bit MATLAB
    (48)     d = '-largeArrayDims' ;
    (49) end

    with the following ones

    if (~isempty (strfind (computer, '64')))
        % 64-bit MATLAB
        d = '-largeArrayDims' ;
        
        % The next three lines are added by jarno.vanhatalo@iki.fi (-09).
        % These options are needed for some reason in Matlab 7.8 or newer. 
        if v >= 7.8 
            d = [d ' -DLONG -D''LONGBLAS=UF_long''']; 
        end
    end


  * Open file SuiteSparse/SPQR/MATLAB/spqr_make.m
  * Go to the line 58
  * Replace the following lines

   (58) if (is64)
   (59)    % 64-bit MATLAB
   (60)    d = '-largeArrayDims' ;
   (61) end

   with the following ones 

   if (is64)
       % 64-bit MATLAB
       d = '-largeArrayDims' ;
    
       % The next three lines are added by jarno.vanhatalo@iki.fi (-09).
       % These options are needed for some reason in Matlab 7.8 or newer.
       if v >= 7.8 
           d = [d ' -DLONG -D''LONGBLAS=UF_long''']; 
       end
   end

  * Open file SuiteSparse/UMFPACK/MATLAB/umfpack_make.m
  * Go to the line 21
  * replace the following lines

   (21) if (~isempty (strfind (computer, '64')))
   (22)    d = ' -largeArrayDims' ;
   (23) end

   with the following ones

   v = getversion ;      % Added by jarno.vanhatalo@iki.fi (-09).
   if (~isempty (strfind (computer, '64')))
       d = ' -largeArrayDims' ;
    
        % The next three lines are added by jarno.vanhatalo@iki.fi (-09).
        % These options are needed for some reason in Matlab 7.8 or newer. 
        if v >= 7.8 
            d = [d ' -DLONG -D''LONGBLAS=UF_long''']; 
        end
   end
