Converted font won't compile as-is

Describe the issue
I used the LittlevGL online font converter tool to convert a font.
I downloaded the resulting C file and added it to my project incorporating the lv_port_esp32_ili9341.
The font source isn't fully compatible with this version of LittlevGL and had errors I had to fix.
It is not actually clear to me whether this is an issue in the font converter being too new, or the code in this port being different, not sure. The errors are minor, here is the diff

rbarris@oryx-i7:~/sandbox/ray/esp1$ diff ~/Downloads/build.c ~/sandbox/ray/esp1/main/build.c

< .class_pair_values = kern_class_values,

.class_pair_values   = (const uint8_t *)kern_class_values,

< .subpx = LV_FONT_SUBPX_NONE,

// .subpx = LV_FONT_SUBPX_NONE,

Code to reproduce the issue

Expected Results
A converted font should integrate smoothly with LVGL

Actual Results
minor compile errors

ESP32 Chip version
m5stack gray

ESP-IDF version
ESP-IDF v4.1-dev-1086-g93a8603c5-dirty

Development machine OS
Ubuntu 17.10

This is because the font converter has been updated to support LittlevGL 6.1, but there are a few minor incompatibilities with 6.0.x now. There are two possible solutions:

• Fix the minor incompatibility the way you did, and continue to use LittlevGL 6.0.
• Upgrade to LittlevGL 6.1; it's a minor release so you shouldn't need to do much work to upgrade.

As the question is answered I close this issue.
