Perl array with SWIG

[airween]

Hi there,

I'm not a Perl expert (I mean the Perl as script lang, and C API), but I would like to solve a problem.

There is a library, written in C, and there are several bindings (Perl, Python, Tcl). SWIG is used to generate the bindings. I found a bug in this part of code: if the type of a variable is "int [NUMBER]" (a fixed length array), then that variable isn't accessible through bindings.

I found a solution for Python (I'm working in Python in many projects - both with interpreter and with C API). I'd like to solve this for Perl too, but it doesn't work.

Here is the (last) code, what I try:

#ifdef SWIGPERL
%typemap(out) int [ANY] {
    AV * av = newAV();
    int i = 0,len = 0;
    printf("len: %d\n", $1_dim0);
    len = $1_dim0;

    for (i = 0; i < len ; i++) {
        SV* perlval = newSV(0);
        sv_setiv(perlval, (IV)$1i);
        av_store(av, i, perlval);
    }
    $result = newRV_noinc((SV *)av);
}
#endif

The name of the variable is "m" in C source, and that a structure. It has a member, called "ilist" (integer list). In Python, I can access to this list like this:

print m.ilist  // produces [0, 3, 6, ....]

In Perl, I just get this:

#!/usr/bin/perl

use example1;

my @m = $example1::m->{ilist};

foreach(@m) {
    print $i, "'", $_, "'\n";
    $i=$i+1;
}

this produces:

0''

and nothing more.
What em'I missing?
Any helps are welcome! Thanks, a.

Okay, at my crossposted post, there is a solution - I just screwed up the assignment... :( http://stackoverflow.com/questions/37634442/swig-typedef-perl-array/37667575#37667575 All of other components were right. Sorry guys, chers, a.
