Couple comments to make it works on x86_64:

- add -fPIC to the CFLAGS/FFLAGS of all Makefile when compiling tron.
- compile using gfortran if you have more recent GCC
- change -lg2c to "-lgfortran -largeArrayDims"
- in mtron.c:154 int dims[] => mwSize dims[]
- mtron.c:306/307 =>
   mwIndex *t = mxGetJc(prhs[7]);
   nnz = (t[n] + 100) * 2;

In regards to memory issues and 64-bit compatibility:

The only changes that need to be made are to replace the int type declarations corresponding to ir and jc in the main routine with mwSize type declarations. Also, in the create_nfo function the int type for the dims array must be replced by an mwSize type.

Hi there,

I'm having memory issues when compiling this on a 64 bit linux machine. I was wondering what hacks needed to be done to make this code work.

pretty good, and easy to use. Needed some hacking for 64bit.
