I'm building an external where I want to create a two dimensional array. I'm following this http://www.tutorialspoint.com/cprogramming/c_multi_dimensional_arrays.htm example which works well with the attached test code, but creates an error when I try to compile my external. The external's code where the array is being declared and initialized is this: float x_iem_coeff[5][2] = { {0.045535, 1.0277}, {0.161621, 1.2569}, {0.393858, 1.96655}, {1.13986, 4.51667}, {6.36341, 22.7468} };
which is in the object structure. The error I get is: overDrive~.c:35:25: error: expected ';' at end of declaration list float x_iem_coeff[5][2] = { ^ ;
I've tried to declare the array in the object structure and initialize it in the new function, but I still got the same error. Any tips?
I solved it by declaring the array in the object structure like this: float x_iem_coeff[5][2];
and in the new function I create another, one dimensional array, and run a nested for loop and set the local array's elements to x_iem_coeff[5][2] one by one. This seemed to work, no errors during compilation. The object crashes Pd when the DSP is turned on, but I guess (and think) it's something else that causes that. The array declaration and initialization shouldn't have anything to do with the DSP state, right?

In C, you can't initialize inside a struct. But you should be able to initialize outside of it. What's the error you get when you try that?

I was getting the same error, but what I was doing was this: In the object structure I would write: float x_iem_filter[5][2];
and in the new function I would write: x->x_iem_filter[5][2] = { {0.1, 0.2}, {0.3, 0.4}, etc.
different values though, this is an example. Then I would get the error: overDrive~.c:35:25: error: expected ';' at end of declaration list float x_iem_coeff[5][2] = {
What I finally did was create a one dimensional array in the new structure like this: float iem_filter[10] = { ten values here };
and in the same function I run this: for(i = 0; i < 5; i++){ for(j = 0; j < 2; j++) x->x_iem_filter[i][j] = iem_filter[index++]; }
which seems to work

it might help very much if you could link to the actual code you are talking about (or post it)¹
float x_iem_coeff[5][2] = {
out of curiosity: are there any specific reasons why you use the "iem" infix? it somehow sounds familiar....

I'm not getting an error any more, it compiles and a d_fat binary is created. It still crushes Pd when the DSP is turned on, but since the initalization of the array is being done when the object is being loaded, before the DSP goes on, it should be something else that crashes Pd, right? I'm still porting here since I started the thread here. I guess moving it to pd-dev wouldn't be painful though.

Yup, I'm trying to convert Mike Moser-Booth's [distortion.mmb~] abstraction into an external and he uses the [lp10_cheb~] abstraction which is based on iemlib's [filter~]. There are five cascaded [lp2c~] abstractions, hence the two dimensional array I want to use. I'm trying to call a function from the perform routine, which simulates [filter~]'s code, five time and each time set different coefficients (The ones given from [lp2c~]).
