preston Posted February 16, 2012 Share Posted February 16, 2012 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.... Link to comment Share on other sites More sharing options...
Larry Posted February 17, 2012 Share Posted February 17, 2012 Just to confirm, are you using C or Objective C? The "iPhone Programming" has me wondering. Link to comment Share on other sites More sharing options...
preston Posted February 20, 2012 Author Share Posted February 20, 2012 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..... Link to comment Share on other sites More sharing options...
preston Posted February 20, 2012 Author Share Posted February 20, 2012 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 Link to comment Share on other sites More sharing options...
Larry Posted February 21, 2012 Share Posted February 21, 2012 Ah, that makes sense. Kudos for figuring it out and thanks for sharing the solution. 1 Link to comment Share on other sites More sharing options...
