  Does anybody have an idea ?

• Include espruino files and components from custom library

  If I include my script with

  SOURCES+= [path to .c file]
  

  first and call it from the wrapper, it loads the included files (like freertos/FreeRTOS.h) correctly.
  But If I try to use CCSOURCES (for cc files, because I am using c++) or SOURCES as well, I cannot include anything there. The "external C" command also not work.
  It looks like I cannot include the .c sources in .cc (c++).

  I need the freeRTOS library for my custom firmware extension. The library is already included as an esp-idf component. How can I refer to it? If I simple use:

  include " ../../esp-idf/components/freertos/include/freertos/FreeRTOS.h"
  

  the other #includes (from the FreeRTOS.h) break. Obviously it is because the includes root is in my lib folder. Moreover, #include doesn't work either.

  My second problems is: If I write my library in c++ (.cc) I also cannot import jspin.h, jsvar.h .... The script doesn't find the files (as a .c script it does).

  I would appreciate some help.

  After hours of try and error:

  The "-std=c++11" needs to be added to "LDFLAGS" line in the Makefile:

  LDFLAGS?=-Winline -g -std=c++11

  I am trying to include my own code in the espruino firmware. My code is partly written in c++. But if I try to build it, it failed:

  Espruino/xtensa-esp32-elf/xtensa-esp32-elf/include/c++/5.2.0/bits/c++0x_warning.h:32:2: error: error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
  

  I tried several ways to set the -std=c++ flag in the Makefile, but I couldn't resolve it.

  (If I mixed something up, I apologize, C is not my native language 😅)

  @Robin
  I am sorry. I understand the "Share what you're working on!" a bit like "I need some help with my project".
  The existing official espruino boards dont fit my needs (ble and wifi), and therefor the only board I can use is the ESP32.
  I thought I could "easily" adapt the smartmatrix library to espruino (save some time), but mabe you are right and I have to dig deeper.

  @MaBe
  Yes I will

• Firmware build fails with library

  in Projects • 4 years, 9 months

  

  My project: I want to use a 64x64 Led matrix on my esp32. I previously used the smartmatrix libray (https://github.com/pixelmatix/SmartMatrix) with the arduino bootloader. This worked fine. Because of the other parts of my project I switched to Espruino. Currently there is no support for 64x64 Hub75e led matrix by the graphics library of espruino.

  I came accross the tutorial to extend the espruino firmware with own c code (https://www.espruino.com/Extending+Espruino+1). I had the idea to include the awesome smartmatrix library to the espruino firmware. Following this tutorial I added my own library to the build (libs/smartmatrix) and include the "SmartMatrix3.c" (inside jswrap_smartmatrix.c) from there. I also added the library to the makefile of the firmware to include it in the build:

  Line 576-580 in the Makefile:

  DEFINES += -DSMARTMATRIX
  INCLUDE += -I$(ROOT)/libs/smartmatrix
  WRAPPERSOURCES += libs/smartmatrix/jswrap_smartmatrix.c
  

  I also managed to include the Arduino.h and pins_arduino.h (smartmatrix uses it)

  But If I want to build the firmware with:

  source scripts/provision.sh ESP32
  make clean && BOARD=ESP32 SMARTMATRIX=1 make
  

  The Build fails! (see Make_output.txt and MatrixCommon.h)

  After some research I found out that the MatrixCommon.h maybe get compiled in C not C++. But how can I tell the make command to compile it in c++ ?

  You can download the whole output text and project: https://drive.google.com/open?id=1vbG4zvenzEVJQdQchtOwsvJmBxBOPwYP

  I dont know If someone understand my problem. Please share your thougts.
