OK, but it turns out it's not excessively difficult to enable x12-arima in
third-party code. Including and calling a function such as the following,
before trying arima estimation via x12a, should do the job:
void my_set_paths (void)
{
ConfigPaths cp = {0};
strcpy(cp.x12a, "x12a");
gretl_set_paths(&cp);
}
The x12a member of the ConfigPaths struct is of length 512 bytes; you
should copy in the full path to the x12a executable unless it is located
in the PATH, in which case just the basename of the executable is
sufficient (as shown above).
The function above uses the syntax of gretl_set_paths() in current CVS. If
you're using libgretl from the gretl 1.9.14 release or earlier there's a
second gretlopt argument required: you should just set this to OPT_NONE,
as in
gretl_set_paths(&cp, OPT_NONE);
