makefile - 无法从 SDK 以外的目录编译 nrf51 SDK 示例

Question

我正在 nRf51 上开发应用程序，因为我正在使用... SDK：nRF51_SDK_7.2.0_cf547b5 工具链：GNU 工具 arm Embedded [arm-none-eabi 版本 4.9.3] 开发板：PCA10028(nRF51 DK)

我正在使用以下示例。C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky 当我在 C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky\pca10028\blank\armgcc 位置使用 makefile 编译此示例时，它可以很好地编译并生成二进制/十六进制.

我想把这个闪烁的例子移到 D Drive。所以现在我的示例位于位置 D:\blinky。我正在使用位于 D:\blinky\pca10028\blank\armgcc 位置的 makefile 编译此示例我已根据此在 makefile 中修改了 SDK PATH

当我在 cmd.exe 中使用“make”编译它时，我得到了

arm-none-eabi-gcc.exe: error: _build/gcc_startup_nrf51.o: No such file or directory
make: *** [nrf51422_xxac] Error 1

对此有任何解决方案吗？谢谢你。

您的绝对源文件路径似乎不正确：

$(TOOLCHAIN_PATH)/components/toolchain/system_nrf51.c
$(TOOLCHAIN_PATH)/components/drivers_nrf/hal/nrf_delay.c 
$(TOOLCHAIN_PATH)/components/toolchain/gcc/gcc_startup_nrf51.s

防止构建相应的对象。

请更新 TOOLCHAIN_PATH - 或使用其他变量 - 以反映您的新 D: 位置。
