c - Initialize a struct -

-

i trying initalize struct getting following error msgs in c:

error: initializer element not constant

error: (near initialization 'resource01.resource.role')

for url works, it's role not working. first had pointer on role , assigned address of variable. removed pointer because don't need , can t assign value variable. doing wrong?

static char const resource01url[] = "/dummy"; static int const resource01role = 2; static struct restresourcenode_s resource01 = {     {         resource01url,         resource01role,         &dummyhandler_call     },     null };  static struct restresourcesmanager_s resourcesmanager = {     &resource01, &resource01 };

the type restresourcenode_s defined:

struct restresourcenode_s {     restresource_t resource;     struct restresourcenode_s const *next; }

and restresource_t:

struct restresource_s {     char const *url;      int const role;      retcode_t (*handle)(msg_t *); };  typedef struct restresource_s restresource_t;

the c99 standard §6.7.8 ¶4 says

all expressions in initializer object has static storage duration shall constant expressions or string literals.

also, const not true constants in c in sense not compile-time constant. means cannot have constant object in initializer of structure has static storage allocation. however, if structure has automatic storage allocation, work fine.

what can define const objects macros - 

#define resource01url "/dummy" #define resource01role 2

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
