conditional compilation macro

[snahmad75]

Hi,

I need to use conditional compilation macro for ESP32. My C++ classes are used on Windows, Kiel and other platform.
Any useful macro I can use. Do I need to define my own macro.


Thanks,
Naeem

I am adding macro for conditional compilation.

CXXFLAGS += -ESP32

xtensa-esp32-elf-c++.exe: error: unrecognized command line option '-ESP32'

I am getting error.

Do define a macro value you supply:

Code: Select all

-D<Name>

or

Code: Select all

-D<Name>=<Value>

You can then use:

Code: Select all

#ifdef NAME
....
#endif

Thanks.
It is working.

CXXFLAGS+= -std=c++11 -DESP32

[ESP_Sprite]

FYI, ESP-IDF itself always defines ESP_PLATFORM , so you can use that as well.
