Compilation error with Ardino/master, lack of newlibc maybe?

[middelink]

Basic Infos

Hardware

Hardware: ESP-12E
Core Version: 2.3.0

Description

Compilation failure after removal of various function due to use of newlibc. Sadly, newlibc is not included so when fetching HEAD, compilation fails miserable under platformio. And likely other projects too

Problem description
I would like to be able to compile projects with esp8266/Arduino :)

Settings in IDE

platformio actually.

Module: NodeMCU ESP12E
Flash Size: 4MiB
CPU Frequency: 80Mhz
Flash Mode: qio
Flash Frequency: 40Mhz
Upload Using: SERIAL
Reset Method: nodemcu

Sketch

Anything which includes some serious use of ESP8266Webserver, mDNS, PubSubClient and/or NTP and likely many other libraries.

Debug Messages

None, as it does not run

Probably platformio issue? If you try compiling in Arduino IDE, it will
compile fine.

Seems that way, since it is not using platform.txt, it did not pick up the newly added path to tools/sdk/libc/... That and the one liner in the linker script.

Adding the paths to the build_flags and a simple manual edit of esp8266.flash.common.ld made it function.

[env:espressif_esp12_board]
platform = espressif
framework = arduino
board = esp12
board_flash_mode = dio
upload_resetmethod = nodemcu
build_flags = -I$PLATFORMFW_DIR/tools/sdk/libc/xtensa-lx106-elf/include -L$PLATFORMFW_DIR/tools/sdk/libc/xtensa-lx106-elf/lib -lc
upload_port = /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0

[n8henrie]

@middelink -- can you be more specific regarding the edit you had to make to esp8266.flash.common.ld? I'd like to get the git version working in Platformio as well.

EDIT: Perhaps this

That said, I finally found official instructions, essentially:

1. Clone repo to $HOME/.platformio/packages/framework-arduinoespressif8266
2. Create package.json in that directory with a modified version:

{
    "description":"Arduino Wiring-based Framework (ESP8266 Core)",
    "name":"framework-arduinoespressif8266",
    "system":"all",
    "url":"https://github.com/esp8266/Arduino",
    "version":"1.20300.1"
}

Then, I modified the build flags used above (apparently $PLATFORMFW_DIR is deprecated in Platformio 3):

build_flags = -I$PIOHOME_DIR/packages/framework-arduinoespressif8266/tools/sdk/libc/xtensa-lx106-elf/include -L$PIOHOME_DIR/packages/framework-arduinoespressif8266/tools/sdk/libc/xtensa-lx106-elf/lib -lc

That got rid of the strcat errors, now I'm just out of memory with my esp01_1m. Oh well.

EDIT2: Think I found the edits to esp8266.flash.common.ld, posting for posterity. Unfortunately still getting section.text' will not fit in region iram1_0_seg' -- even when I add -Wl,-Tesp8266.flash.1m64.ld to build_flags or change the board to an esp12e (which has four times the flash size). Not sure what's going on.

[middelink]

Greetings,

My current (working) platformio.ini has the following build_flags:
build_flags = -I$PIOHOME_DIR/packages/framework-arduinoespressif8266/tools/sdk/libc/xtensa-lx106-elf/include -L$PIOHOME_DIR/packages/framework-arduinoespressif8266/tools/sdk/libc/xtensa-lx106-elf/lib -lc

So if you run it like this, it will run out of .text space, as it will now include Arduino's libc implementation. So we need to move that to the .irom0.text segment.

Done.

EDIT2: Personally I did not copied the repo directly into the platformio stuff, I simply linked it to my existing repo.

[n8henrie]

Got it -- the platformio team just added a more "official" way to install the dev branch that works great, very user friendly.

Issue there / my steps

EDIT: More specifically, I was able to remove all the additional build flags, didn't need to edit esp8266.flash.common.ld -- just installed and it worked.

[middelink]

Yup, just followed their steps and it seems to work. Less happy with the fact that the staging framework is installed OVER the normal one, so my "production" builds now also use the staging framework, even though they have platform = espressif8266, that for me is a showstopper :(

EDIT2: Guess I have to take it back, after uninstalling both frameworks and reinstalling them, it seems to work for both type of projects.
