Despite REQUIRES console vfs, I still get "undefined reference to esp_vfs_dev_cdcacm_set_rx_line_endings"

[godzilla2]

Hi,

I am trying to integrate the 'console' example into my project.

I can compile the example, just fine. But when I copy paste the code into my project, I get this error:

Code: Select all

undefined reference to esp_vfs_dev_cdcacm_set_rx_line_endings

I've hit these isssues before, and usually they are resolved by finding the right component and adding it to idf_component_register( .... REQUIRES "console" "vfs" ....) section of my CMakeLists.txt (See below).

But in this case, it does not work. I've tried moving things around a bunch, I cannot figure out why.

I'm using esp-idf 4.4 (Master) from June 25th 2021. I've also tried esp-idf 4.4 (Master) from Septempber 9th 2021. Same issue.

What could be causing this?

I've tired:
1. adding a REQUIRES "console" "vfs" to jcord-app (as opposed to jcord-common)
2. copying the vfs & console component directories into /jcord-firmware/jcord-app/components
3. updating esp-idf

My project is laid out like this:

I made a small test app that reproduces the issue with a single project. Maybe its some weird sdkconfig.

Still debugging, but looks like I might want to use:

Code: Select all

esp_vfs_dev_uart_port_set_rx_line_endings

Looks like I accidentally copied my code from 'console_usb' instead of 'console'.
