trying to get the wear levelling example in espidf working in arduino
https://github.com/espressif/esp-idf/bl ... ple_main.c
Compiles under the espidf make
Add the Arduino component, receives an error regarding the variables in the line
const esp_vfs_fat_mount_config_t mount_config = {
.max_files = 4,
.format_if_mount_failed = true
};
which are the wrong way round - corrected that and it fails on :-
C:\Users\Fugazi\Documents\sloeber-workspace\wl\Release/../wl.ino:54: undefined reference to `esp_vfs_fat_spiflash_mount(char const*, char const*, esp_vfs_fat_mount_config_t const*, int*)'
C:\Users\Fugazi\Documents\sloeber-workspace\wl\Release/../wl.ino:79: undefined reference to `esp_vfs_fat_spiflash_unmount(char const*, int)'
Spent the whole day trying every which way possible to sort this, please someone help !!! ?
Thanks

Re: undefined reference to `esp_vfs_fat_spiflash_mount
In your INO sketch, do you simply include the "esp_vfs_fat.h" ?
In such case, linker try to find the functions as C++ not C, and there are not in the library ...
You need to include it that way :

You need to include it that way :
Code: Select all
extern "C" {
#include "esp_vfs_fat.h"
}
