I have a problem with my project where I want to use
#include <functional>
#include <map>
In platformio.ini I have two env
[env:pcf_test_arduino]
platform = atmelavr
board = nanoatmega328
framework = arduino
lib_deps =
PCF8574
[env:pcf_test_esp]
platform = espressif8266
board = nodemcuv2
framework = arduino
lib_deps =
PCF8574
When I build with pcf_test_esp, everything is ok, build with pcf_test_arduino - failing with functional or map no such file or directory. Where try to find the problem?
Meaby I will find something in c_cpp_properties.json ?
The underlying AVR-G++ doesn’t support the full standard C++ library.
This issue has been around with their compiler forever and will probably never be fixed.
See e.g. topic Enabling RTTI (-frtti) causes undefined reference to `__dynamic_cast'
You may try adding
platform_packages =
toolchain-atmelavr@~2.70300.0
to the Atmel-AVR environment, to get a newer compiler, but I’m 99% certain the compiler will still fail.
@maxgerhardt thanks for that info, now I found something about this and I know where is the problem. I Tried with another version and nothing. I found the ArduinoSTL library and maybe this will help me.
