测试demo来自：《AN_N32G45x_N32G4FR_N32WB452_N32G43x_N32L43x_N32L40x_GCC开发环境应用笔记_V3.0》
搭建GCC开发环境时，修改makefile文件，把算法库添加进来，但编译失败了。不添加lib，编译可以通过，功能也正常。有大佬实现过在在GCC添加lib吗，求帮忙看看
makefile 部分代码：- ######################################
- # Algo libs
- ######################################
- USELIB = 1
- ######################################
- # Lib files
- ######################################
- ifeq ($(USELIB), 1)
- SRC_LIB_DIR += ../../../../../../firmware/$(TARGET_PLATFORM)_algo_lib/lib
- INC_LIB_DIR += ../../../../../../firmware/$(TARGET_PLATFORM)_algo_lib/inc
- LIB_SOURCES = $(foreach DIR3, $(SRC_LIB_DIR), $(wildcard $(DIR3)/*.lib))
- LIB_SOURCES_L = $(addprefix -L,$(LIB_SOURCES))
- C_LIBS = $(LIB_SOURCES_L)
- LIB_INCS = $(foreach DIR4, $(INC_LIB_DIR), $(wildcard $(DIR4)/*.h))
- LIB_INCS_PATH = $(sort $(dir $(LIB_INCS)))
- LIB_INCS_PATH_I = $(addprefix -I,$(LIB_INCS_PATH))
- C_INCLUDES += $(LIB_INCS_PATH_I)
- endif
测试n32g45x_algo_common.lib中的函数SetZero_U8()- uint32_t SetZero_U8(uint8_t *dst, uint32_t byteLen);
main.c部分代码：
- #include "n32g45x_algo_common.h"
- uint8_t dat[8];
- int main(void)
- {
- /*SystemInit() function has been called by startup file startup_n32g45x.s*/
- LedInit(GPIOA, GPIO_PIN_8);
- for (int i = 0; i < 8; i++)
- {
- dat[i] = i;
- }
- SetZero_U8(dat,6);
- while (1)
- {
- LedBlink(GPIOA, GPIO_PIN_8);
- systick_delay_ms(100);
- }
- }
编译后报错信息：
d:/gcc-arm/gnu arm embedded toolchain/10 2021.10/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe: build/main.o: in function `main':
E:\Desktop\Nationstech.N32G45x_Library.2.0.0\projects\n32g45x_EVAL\examples\GPIO\LedBlink\GCC/../src/main.c:174: undefined reference to `SetZero_U8'
collect2.exe: error: ld returned 1 exit status
make: *** [makefile:143: build/output.elf] Error 1
提示未定义SetZero_U8函数，是我使用方式不对吗？lib文件在makefile中都有引用了，路径检查了也没问题。
