[solved] {fmt} and xtensa-esp32-elf-g++ 8.2.0 (crosstool-NG esp32-2019r1)
Posted: Tue Oct 08, 2019 6:16 pm
Hi,
I'm trying to use {fmt} (https://fmt.dev) in my project, but I'm stuck on the linker step - I suspect that there are missing pieces in the toolchain.
The first few lines of the error message are these:
Is this something Espressif devs recognise as not implemented in the named tool chain?
Thanks,
Update: These are all implemented - its just one of my project that fails with these errors for some reason, others builds fine with {fmt}.
