posix write(2) failes.. #403

Closed mgliewe closed 2 years ago

mgliewe commented 2 years ago

For some reason, the write(2) calls are failing on my build, resulting in ENOENT errors on each call.

This envolves the buildin edit() and dropbear not able to create its needed support files.

I temporally fixed that by patching both to use stdio calls (which are working fine), but i'm sure i was just curing the symptoms..

No C-code reference. No Lua code. No idea what you're talking about.

sorry to have been so brief and confused, it was a long night... The problem was (is) that posix write() calls in C on the filesystem are failing with ENOENT, whereas stdio fwrite() calls succeed. That only applies to write() calls, open()/read() et al calls are working.

See https://github.com/mgliewe/Lua-RTOS-ESP32/commit/c0383af8ed16350f50ef3bf285a93f2046586e4c how i worked around that. I assume thats a problem i have with my toolchain, but i thought i should report it anyway as it had cost me some headache

Thanks for the link, now I understand what you mean. That issue hasn't occurred on my system. If I ever see it, I'll of cause let you know the solution 👍
