(Solved) Help with error in LFS library (Building on ESP8266)

lawrencerb · June 13, 2019, 8:12pm

I’m trying to build with the following mos.yml:

[“i2c.enable”, true]
[“spi.enable”, true]

libs:

origin: https://github.com/mongoose-os-libs/boards
origin: https://github.com/mongoose-os-libs/demo-bundle
origin: https://github.com/mongoose-os-libs/rpc-service-i2c
origin: https://github.com/mongoose-os-libs/spi
origin: https://github.com/mongoose-os-libs/vfs-dev-spi-flash
origin: https://github.com/mongoose-os-libs/vfs-fs-lfs

manifest_version: 2017-05-18

Following error always appear even with different code:

“Build Failed”

Any insights?

Never used LFS with ESP8266. Add the following lines in mos.yml and rebuild.

cflags:
  # avoid format parameter errors
  - "-Wno-format"

It worked!
My dearest thank you, nliviu

Will mark as solved and update the issue as LFS building in ESP8266.
