Atmel Studio 7 - ссылка на библиотеку неопределенных функций * stati c

0 голосов
/ 29 марта 2020

У меня есть решение с двумя проектами: - stati c library - исполняемый файл

Exe c Проект, очевидно, зависит от библиотеки. Компилятор может выяснить, где находится библиотека, и я могу использовать все (например, определенные символы), кроме содержимого в IO. c. В выходной папке я могу найти скопированный IO.o, поэтому библиотека работает нормально. Ошибка должна быть на стороне проекта exe c, но я не знаю, где ее искать. Google подвел меня, или я ищу в неправильном направлении.

Stati c Библиотечный проект имеет такую ​​структуру: 

ATMEGA2560
|-headers
| |-IO.h
|-source
| |-IO.c
|-ATMEGA2560.h

Исполняемый проект имеет следующую структуру: 

|-main.c

Компилятор включает пути: 

../../ATMEGA2560/Release/headers <- IO.h
../../ATMEGA2560/Release/ <- ATMEGA2560.h

Все параметры компилятора 

-x c -funsigned-char -funsigned-bitfields -DNDEBUG  -I"E:\ATMEL\7.0\Packs\atmel\ATmega_DFP\1.3.300\include" -I"../../ATMEGA2560/Release/headers" -I"../../ATMEGA2560/Release"  -O3 -ffunction-sections -fdata-sections -fpack-struct -fshort-enums -mrelax -Wall -Wextra -Wundef -mmcu=atmega2560 -B "E:\ATMEL\7.0\Packs\atmel\ATmega_DFP\1.3.300\gcc\dev\atmega2560" -c -std=gnu99 -v -MD -MP -MF "$(@:%.o=%.d)" -MT"$(@:%.o=%.d)" -MT"$(@:%.o=%.o)"

Библиотеки компоновщика: 

libm
libATMEGA2560

Пути к библиотекам компоновщика: 

../../ATMEGA2560/Release <- libATMEGA2560.a

Все параметры компоновщика:

Возможно, это просто опечатка, но вы говорите, что ваша библиотека stati c имеет структуру: 

ATMEGA2560
|-headers
| |-IO.h
|-source
| |-IO.c
|-ATMEGA2560.h

, но вы ссылаетесь на каталог с папкой Release в нем, например, 

ATMEGA2560
|-Release
| |-headers
| | |-IO.h
| |-source
| | |-IO.c
| |-ATMEGA2560.h
