WinAVR a Programmers notepad

[Jan Waclawek]

Ach jaj.

.h nie je kniznica a nelinkuje sa. #include je doslovne vlozenie. Linkuje sa prelozeny .c, obvykle nazyvany .o alebo .obj, a "pridava" sa to do prikazu pre linker. To vo Vasom pripade bude schovane v makefile.

Toto je problematicke len tak vyguglovat, lebo sa to historicky poklada za zakladnu znalost kazdeho kto robi v C.

Poslite ten makefile a meno suboru, v ktorom mate tie Vase funkcie.

wek

>Zkousim misto AVR Studia program Programmer's notepad (zda se mi v nem zobrazeny kod prehlednejsi a vubec proc to nezkusit). Zalozim projekt s jednim zdrojovym .c souborem. Zkopiruju do adresare kde je zdrojovy .c soubor makefile z c:\WinAVR-20100110\sample\Makefile. Takto jednoduchy priklad zkompiluju bez problem, ale jakmile mam svoji vlastni .h knihovnu a do do zdrojoveho .c ji prilozim, compiler hodi chybu undefined reference to (a ted je jmeno procedury z knihovny)... Nejspis to je tim, ze neni v makefile nadefinovano, aby to linkovalo i "uzivatelske".h soubory. Kde se to da nastavit (co editovat/pridat). Googluji uz peknou chvilku, ale nic o tom nemuzu najit.
