Hi All,

 

Im trying to solve a problem with C struct.

This is the structure of the struct in header file that is 'included':

 

struct plantbl {

char max_harmonic[9];

char max_power_of_t;

signed char *arg_tbl;

double *lon_tbl;

double *lat_tbl;

double *rad_tbl;

double distance;

};

 

 

To use this struct, the current code is in this format:

 

static struct plantbl FAR mer404 = {

{ 11, 14, 10, 11, 4, 5, 2, 0, 0,},

6,

merargs,

mertabl,

mertabb,

mertabr,

3.8709830979999998e-01,

};

 

However the above code produces this error:

 

/Users/bliss/Documents/iPhone_Programming/My XCode 4.1 Apps/SwissTest/swemptab.c:1091: error: variable 'mer404' has initializer but incomplete type

 

FAR btw is a Macro defined as:

 

 

# ifndef FAR

# define FAR

# endif

# define MALLOC malloc

# define CALLOC calloc

# define FREE free

#else

# ifndef FAR

# define FAR far

# endif

# ifdef __BORLANDC__

# include <alloc.h>

# define MALLOC farmalloc

# define CALLOC farcalloc

# define FREE farfree

# else

# define MALLOC _fmalloc

# define CALLOC _fcalloc

# define FREE _ffree

# endif

#endif

 

 

So anyway...I decide to recode the mer404 to something I thought will be equivalent to the intention of the code above but hopefully does not result in a error...

so I changed the code to:

 

 

char placeholder[9] = { 11, 14, 10, 11, 4, 5, 2, 0, 0,};

 

static struct plantbl FAR mer404 = {

placeholder,

6,

merargs,

mertabl,

mertabb,

mertabr,

3.8709830979999998e-01,

};

 

but I still get the following error:

 

 

/Users/bliss/Documents/iPhone_Programming/My XCode 4.1 Apps/SwissTest/swemptab.c:1080: error: variable 'mer404' has initializer but incomplete type

 

 

Now I don't understand why this would be happening....I am trying to feed in values to each of the 7 elements/properties of the struct plantabl..........

 

Can someone enlighten me on what to do to solve this problem please??? Thank you very much.... :)

Hi Larry,

I am using C Programming Language inside Xcode which I'll be mixing with Objective-C eventually, but the example code above that I am asking about is C Programming Language. Thank you very much.....

Hi Larry,

 

I've figured it out.....the source files in the C Library I am using had not included the corresponding header files with the declaration of the structs. I've added them and it now compiles properly.

Thank you for trying to help :)
