conflicting types of '__putchar()' #2

Closed pescara closed 4 years ago

pescara commented 4 years ago

Hi I downloaded your code and tryied to build it in Segger Embedded Studio. But there the error comes: "conflicting types of '__putchar()'

(1) you declare it in stdio.h as follow: int putchar(int, printf_tag_ptr);

(2) then in rectarget.c it is defined as following: int __putchar(int ch, FILE * p_file) { UNUSED_PARAMETER(p_file); UNUSED_VARIABLE(app_uart_put((uint8_t)ch)); return ch; } Can you help me? Is is ok if I just uncomment the (2) declaration? Will it still run? I'm very very pleased for any help since my thesis will highly depend on it... : (

Hello, it looks like this file has been updated in more recent nRF5 SDK versions. Can you try the attached retarget.c (copied from nRF5 SDK 16.0.0)?

retarget.zip

@nordic-auko Tested it and it seems like a functioning workaround. Can you update it? Should I generate a PR? Also I think the project should embed a .gitignore like the following gitignore.zip

Thanks, @m3x1m0m ! I plan to bump this repo to the latest SDK version sooner rather than later anyway, so there's no need for a PR. And thanks for the tip regarding .gitignore!
