I am working on a Jitter MOP c-external with two inputs and two outputs:

 mop = jit_object_new(_jit_sym_jit_mop, 2, 2);

As far as i understand, this would be the usual way to access the different input and output matrices:

in_matrix = jit_object_method(inputs, _jit_sym_getindex, 0);
in2_matrix = jit_object_method(inputs, _jit_sym_getindex, 1);

out_matrix = jit_object_method(outputs, _jit_sym_getindex, 0);
out2_matrix = jit_object_method(outputs, _jit_sym_getindex, 1);   

if (x && in_matrix && in2_matrix && out_matrix && out2_matrix) {

    in_savelock = (long)jit_object_method(in_matrix, _jit_sym_lock, 1);
    in2_savelock = (long)jit_object_method(in2_matrix, _jit_sym_lock, 1);
    out_savelock = (long)jit_object_method(out_matrix, _jit_sym_lock, 1);
    out2_savelock = (long)jit_object_method(out2_matrix, _jit_sym_lock, 1);

    jit_object_method(in_matrix, _jit_sym_getinfo, &in_minfo);
    jit_object_method(in2_matrix, _jit_sym_getinfo, &in2_minfo);
    jit_object_method(out_matrix, _jit_sym_getinfo, &out_minfo);
    jit_object_method(out2_matrix, _jit_sym_getinfo, &out2_minfo);
  
    jit_object_method(in_matrix, _jit_sym_getdata, &in_bp);
    jit_object_method(in2_matrix, _jit_sym_getdata, &in2_bp);
    jit_object_method(out_matrix, _jit_sym_getdata, &out_bp);
    jit_object_method(out2_matrix, _jit_sym_getdata, &out2_bp);

In this case it seems, that every output matrix has the same properties than the leftmost input matrix. 

But I would need to define different types, planecounts, dim sizes for each input and output matrix like these ones inside the matrix_calc function:

jit_matrix_info_default(&posMatrixInfo); //for out_matrix
posMatrixInfo.planecount = 3;
posMatrixInfo.dimcount = 1;
posMatrixInfo.dim[0] = posSize;
posMatrixInfo.type = _jit_sym_float32;
posMatrix = jit_object_new(_jit_sym_jit_matrix, &posMatrixInfo);

jit_matrix_info_default(&indexMatrixInfo); //for out2_matrix
indexMatrixInfo.planecount = 1;
indexMatrixInfo.dimcount = 1;
indexMatrixInfo.dim[0] = indexMatrixSize; 
indexMatrixInfo.type = _jit_sym_long;
indexMatrix = jit_object_new(_jit_sym_jit_matrix, &indexMatrixInfo);

So how and at wich point can i define my output matrices in the right way?

So I have been making standalone apps for a long time, and we have one of them that works fine on Mac, but causes windows to crash but only on certain machines (not sure why). The concept we employ for our suite are "Modular Apps", so we have separate standalones for different purposes. For example, one is a spout "hub" that we round trip video to multiple apps at once. In other words, to use our suite, you need to have a couple of standalones open at once.

The one common feature is that people report is that they are able to open the app in question and it seems to run, but when they shut it down and open it again later, it crashes immediately. 

, but I was wondering if it was because we need to find a way to differentiate each app during the build process, that maybe the other apps are using a similar memory address because windows sees each standalone as "max"? 

This is the last guess before we attempt to write a new external MXO (which is the current culprit) as it is likely a memory leak issue (why windows vs mac I have no idea), but I thought i'd ask the community before we go down that rabbit hole.

For a jitter MOP external i want to use two matrices as input and two matrices as output. For the output matrices i want to calculate some values and store it into a t_linklist for sorting the values wich are of the type connector_linesAB:

typedef struct
{
    float x;
    float y;
    float z;
} connector_point_Vec3;

typedef struct
{
    connector_point_Vec3 facePoint;
    long faceIndex;
    connector_point_Vec3 singlePoint;
    long singleIndex;
    float length;
} connector_linesAB;

The sorting and calculation of the output matrices should be done in the matrix_calc function:

t_jit_err connector_lines_matrix_calc(t_connector_lines* x, void* inputs, void* outputs)
{
    t_jit_err err = JIT_ERR_NONE;
    t_linklist* linesList = linklist_new();

    t_jit_matrix_info in_minfo, in2_minfo, out_minfo, out2_minfo;
    void *in_matrix, *in2_matrix, *out_matrix, *out2_matrix;
    char* in_bp, * in2_bp;
    float* indata, *indata2, *pospointer1, *pospointer2;
    long in_savelock, in2_savelock, out_savelock, out2_savelock;
    in_matrix = jit_object_method(inputs, _jit_sym_getindex, 0);
    in2_matrix = jit_object_method(inputs, _jit_sym_getindex, 1);

    out_matrix = jit_object_method(outputs, _jit_sym_getindex, 0);
    out2_matrix = jit_object_method(outputs, _jit_sym_getindex, 1);   

    if (x && in_matrix && in2_matrix && out_matrix && out2_matrix) {

        in_savelock = (long)jit_object_method(in_matrix, _jit_sym_lock, 1);
        in2_savelock = (long)jit_object_method(in2_matrix, _jit_sym_lock, 1);
        out_savelock = (long)jit_object_method(out_matrix, _jit_sym_lock, 1);
        out2_savelock = (long)jit_object_method(out_matrix, _jit_sym_lock, 1);

        jit_object_method(in_matrix, _jit_sym_getinfo, &in_minfo);
        jit_object_method(in2_matrix, _jit_sym_getinfo, &in2_minfo);

        jit_object_method(out2_matrix, _jit_sym_getinfo, &out2_minfo);
  
        jit_object_method(in_matrix, _jit_sym_getdata, &in_bp);
        jit_object_method(in2_matrix, _jit_sym_getdata, &in2_bp);
       
        if (!in_bp || !in2_bp) { err = JIT_ERR_INVALID_INPUT; goto out; }
        
        indata = (float*)(in_bp);
        indata2 = (float*)(in2_bp);
       
        for (int i = 0; i < (&in_minfo)->dim[0]; i++) {
            long offsetFacePoint = (&in_minfo)->dimstride[0] * i;
            pospointer1 = (float*)(in_bp + offsetFacePoint);
            connector_point_Vec3 facePoint;
            facePoint.x = pospointer1[0];
            facePoint.y = pospointer1[1];
            facePoint.z = pospointer1[2];

            for (int j = 0; j < (&in2_minfo)->dim[0]; j++) {

                long offsetSinglePoint = (&in2_minfo)->dimstride[0] * j;

                connector_linesAB* newLine = (connector_linesAB*) sysmem_newptr(sizeof(connector_linesAB));
                newLine->faceIndex = i;
                newLine->facePoint = facePoint;

                linklist_append(linesList, newLine);
            }

        }

        count = linklist_getsize(linesList);
        for (i = 0; i < maxSinglePoints; i++) {

            post("length=%f", data->length);
        }
         
        jit_object_method(out_matrix, _jit_sym_frommatrix, in_matrix, NULL);
        jit_object_method(out2_matrix, _jit_sym_frommatrix, in2_matrix, NULL);   
        
    }
    else {
        return JIT_ERR_INVALID_PTR;
    }

out:
    object_free(linesList);
    jit_object_method(out2_matrix, _jit_sym_lock, out2_savelock);
    jit_object_method(out_matrix, _jit_sym_lock, out_savelock);

    jit_object_method(in_matrix, _jit_sym_lock, in_savelock);
    return err;
}

The memory allocation, adding Values and sorting the list seems to work but at the end of the matrix_calc function i want to free the memory with the object_free function. When i call the object_free function with the t_linklist i got following error messages:

So how do i do the right memory managment with t_linklist and my own struct types?

For a jitter MOP external i want to use two matrices as input and two matrices as output. For the output matrices i want to calculate some...

I have some custom-built externals which work perfectly fine in Max itself, but whenever I try to build a standalone with them I get "no such object" errors. I have tried including the .mxe64 files themselves and tried including the folder they're in. I've tried putting them in the main Max externals folder. I've tried building a collective instead of a standalone executable. I have verified that the .mxe64 files are actually present in the resources folder of the built standalone, but it just does not seem to matter (and I have tried manually moving them to the resources folder even though they already exist there). The strangest thing of all is that out of all the countless times I've tried to build, it actually did work maybe two or three times when I saved the patch as a project first and then built it. But I can't get that to work anymore now either. I have verified that it acts the same way on a different computer.

I feel like I've tried everything. Any ideas what could possibly be causing this?

i am currently trying to update a patch of mine to 64 bit since i need more memory. and i am very badly missing the jit.freenect.grab external which only runs in 32 bit.

i asked the programmer, jean marc pelletier, directly and this was his reply:

"Hi, sorry, I don’t have any time to dedicate to this project anymore… It’s open source, so if some enterprising soul (wink, wink) wants to have a stab at re-compiling, that would be great."

now... since i never compiled anything myself i am wondering: might there be any 'enterprising soul' out there who is working on this?

I still did not get an answer to my question so i try to edit my original post for better understanding and reproducing my Problem to hopefully some hints to my issue:

I am writing an jitter external for Max 9.0.8 with max-sdk-8.2.0:

max.testexternal.c.txt

testexternal.c.txt

Inside the external i am filling a 2x2x3 matrix and storing the matrix to brightnessTest.jxf in the Filesystem. After reading back into a matrix object i want to get the stored Values back in a jitter Patch.
