Re: Change in handling of nested structs from 1.3.36?

Solomon Gibbs wrote:

I have a rather nasty struct in the code I'm wrapping. Though version 1.3.36, swig has always consumed it without complaining. However, I recently downloaded 1.3.39 and now I get a syntax error at the line corresponding to the end of the "meta_size" struct (below). The preprocess result from running swig with -E looks like more or less what I would expect.

Does anyone have any idea what has changed, or how to figure out I am doing wrong? I've tried a couple of the --debug-* options, but the parse seems to stop before they can have any effect.

Any help would be appreciated.

The following struct doesn't seem to work under 1.3.38 or 1.3.39. I haven't checked 1.3.37.

typedef struct H5O_info_t {
   unsigned long     fileno;
   haddr_t         addr;
   H5O_type_t         type;
   unsigned         rc;
   time_t        atime;
   time_t        mtime;
   time_t        ctime;
   time_t        btime;
   hsize_t         num_attrs;
   struct {
       unsigned version;
       unsigned nmesgs;
       unsigned nchunks;
       unsigned flags;
       struct {
           hsize_t total;
           hsize_t meta;
           hsize_t mesg;
           hsize_t free;
       } space;
       struct {
           uint64_t present;
           uint64_t shared;
       } mesg;
   } hdr;
   struct {
       H5_ih_info_t obj;
       H5_ih_info_t attr;
   } meta_size;
} H5O_info_t;

I don't get any error using this struct and I don't see any problems using valgrind on SWIG for this struct. I think the best thing is for you to provide the exact commandline options you are passing to SWIG and provide a complete standalone interface file that shows the problem. Also which operating system, compiler and compile options you used to compile SWIG.
