c - Uninitialized variable put into program memory area. AVR programming -

-

in xxx.h file have declaration:

const struct menuitem menuitema;

in xxx.c file have definition:

const struct menuitem menuitema progmem = {texta, menuitemafunction, &menuitemb, 0};

i include xxx.h file in main.c file. while building project warning:

uninitialized variable 'menuitema' put program memory area [-wuninitialized]

when had declaration , definition in same .c file ok, have no idea wrong now.

joachim correct, definitions in header files need extern - otherwise every time use header (in different source file) you'll create copy of variable. answer original question, suspect variable in code section because constant, if remove const it'll go bss or data section depending on how it's defined. you're main problem lack of extern

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
