PlatformIO ignores #ifdef Includes

bastian0302 · April 5, 2020, 3:10pm

Hallo together,
i have following problem.
After a Update for Platformio the #include “file” in preprocessor #ifdef get ignored.

#ifndef DeviceDefinition_H
#define DeviceDefinition_H
#include "Arduino.h"

#define USE_MCP23017

#ifdef USE_MCP23017     
    #include "MCP23017.h"
    MCP_23017Class Device;
#endif
#ifdef USE_Gateway
    #include "Gateway.h"
    GatewayClass Device;
#endif
#ifdef USE_PCA9685   
    #include "PCA9685.h"
    PCA9685Class Device;
#endif
#endif

Befor the update all works fine. But now it throw a “no such file” error message. If i define the Class
outside the #ifdef it works again.

I tryed to clean the project, deleted the .pio folder, changed lib_ldf_mode from chain+ to deep+.

But nothing helped.

Does anyone have the same troubles?

Thanks for help

Can you post the exact error? Is it a compiler error or a VSCode intellisense error? If it’s a compiler error, what’s the full log?

Thats the Error i get .

I don’t even find a reference for a library which implements MCP_23017Class. Which library do you use? Does declaring it in lib_deps help?

If not, can you share a minimal project which reproduces the problem?

bastian0302 · April 5, 2020, 4:50pm

Puh thats a little bit tricky.

main.cpp

 #include "Arduino.h"
 #include "GlobalFunction.h"
 void setup() {
 InitDevice();
 }
 void loop()
 { 
 }

GlobalFunction.h

#ifndef GlobalFunction_H
#define GlobalFunction_H
 void InitDevice();
#endif

GlobalFunction.cpp

#include "GlobalFunction.h"
#include "DeviceDefinition.h"
void InitDevice(){
   if(!Device.Init_Task()){
   }
}

DeviceDefinition.h

#ifndef DeviceDefinition_H
#define DeviceDefinition_H
   #include "Arduino.h"
   #define USE_MCP23017        
   #ifdef USE_MCP23017        
         #include "MCP23017.h"
         MCP_23017Class Device;
   #endif
#endif

Soo i try to explain.
There are several ESP32 and they got different Perepherie one for example the MCP23017.
In the DeviceDefinition.h i choose which perepherie the compilier have to use.
I want to have a changeble Instance of “Device.” and this worked until the newest update.
Now: if i put the #include “MCP23017.h” in “DeviceDefinition.h” befor the “#ifdef Use_MCP23017” it works all fine.

Please remove a space before lib_ldf_mode

bastian0302 · April 24, 2020, 3:03pm

Thanks for reply but the space only happend because of copy and paste and than format the code in the reply message editor.
Strange is the following.

I bind in the “Device” library in the DeviceDefinition.h. (wich is part of the GlobalFunction Folder)
If i choose the Gateway.h wich is befor the GlobalFunction folder than it works, but if i choose the MCP23017.h or PCA9685 than is get the error.

Thanks and a nice weekend.

Hi @bastian0302

Did you find a solution for this?

I have more or less the same issue:
Want to use Platform-IO with the WOKWI-plugin.

Right now, the simulation uses an I2C-Touch-Input,
my real Hardware uses an SPI-Touch-Input

Both use TS_Point-Classes, so everything should be great including the one or the other… inside the Code the Preprocessor works.
outside (global) the Preprocessor does not work for includes

#define WOKWI

// Touchscreen
#ifdef WOKWI
#include <Adafruit_FT6206.h>
#else
#include “XPT2046_Touchscreen.h”
#endif

I get a lot of Linking-Issues …
Best described, if I just include both

.pio/libdeps/esp32-s3-devkitc-1/XPT2046_Touchscreen/XPT2046_Touchscreen.h:33:7: error: redefinition of ‘class TS_Point’

sure I can fix if by commenting the one or the other, but that is the whole point of preprocessor statements :-/

Hallo robinblood,

i used the platformio.ini, where i created 2 Devices (not related to my original request)
and there is a keyname " lib_ignore = DTS726D "
But for this you have to create a library.json
{ "name": "DTS726D", "version": "1.0.0", "description": "3-Phase Energy Meter ", "keywords": "CNC, Energy Meter", "authors": [ { "name": "xxxx" } ] }
So you create the libraries and every on gets such a library.json.
And the devicedefinition in the platformio.ini exlude the othere library.
