"flockfile" and "funlockfile" aren't defined in ESP32?

[girvo]

Hey mate, neat project. I am trying to stand up a new PlatformIO project with a FireBeetle32 using it, but have run into build errors (with the latest PIO and Nim):

Linking .pio\build\firebeetle32\firmware.elf
.pio\build\firebeetle32\src\nimcache\stdlib_io.nim.cpp.o:(.literal._Z11echoBinSafePP13NimStringDesci+0x8): undefined reference to `flockfile'
.pio\build\firebeetle32\src\nimcache\stdlib_io.nim.cpp.o:(.literal._Z11echoBinSafePP13NimStringDesci+0x10): undefined reference to `funlockfile'
.pio\build\firebeetle32\src\nimcache\stdlib_io.nim.cpp.o: In function `echoBinSafe(NimStringDesc**, int)':
C:\Users\JoshGirvin\Code\new-firmware/src\nimcache/stdlib_io.nim.cpp:55: undefined reference to `flockfile'
C:\Users\JoshGirvin\Code\new-firmware/src\nimcache/stdlib_io.nim.cpp:73: undefined reference to `funlockfile'

Obviously, trying to remove the reference to those doesn't do anything as they're regenerated. Any ideas how to work around this? According to ESP-IDF those definitions are basically noops as they haven't implemented them?

espressif/esp-idf#2565

Cheers!

Thanks for reporting, @girvo! I'll take a look in the coming days. If possible, could you share your code so that I can quickly reproduce the issue?

I haven't been able to reproduce this so far @girvo. Are you perhaps trying to use file i/o?
