Compilation under Arduino ESP8266?

[benjamind]

Trying to build this in the Arduino IDE, and with Platform.io, for an ESP8266.

I brought the two v7 files in, set CS_PLATFORM to CS_P_ESP_LWIP and CS_BUILD_PROFILE to minimal. But I get an undefined reference to 'ctype_ptr' error.

Seems we're missing a bunch of stdio functions, fprintf, and setjmp as well. Any ideas how to go about fixing this?

@dimonomid could you address it please?

I've found that I can compile this using the feature/libc branch of Arduino ESP8266, after adding the putc.a symbols back into the libcmin build. Compilation and linking now work with CS_DISABLE_STDIO and V7_BUILD_PROFILE 1, however I get a crash on v7_create().

So the stack trace gives me this:

Looks like an issue in calloc, not sure how to proceed from here. Anyone else had any luck compiling under ESP8266 Arduino?

Manually add the esp8266 arduino board support (follow the instructions here: https://github.com/esp8266/Arduino#using-git-version) instead of using the board manager from the arduino ide ...
