.hpp header files seems to compile in C and not C++

Development Platforms
1

Hi.

I’m switching from TFT_eSPI to LovyanGFX library and when building, I get multiple errors "error unknown type name ‘namespace’ " on such line in .hpp header files :

namespace lgfx
{
...

It leads me to think that it is not compiling in C++, but rather in C as it doesn’t seem to recognize the “namespace” keyword.

I added the LGFX library with this platformio.ini line :

lib_deps = lovyan03/LovyanGFX@^1.1.12

Here is the build command line for this library :

Any idea how I could solve this problem ?

Do you change an existing project from TFT_eSPI to LovyanGFX?

What happens if you create an empty new project which uses the LovyanGFX?
Does the error then also occur?

An error log could be helpful.

Hi.

The project initially didn’t use any display. I first added a display using TFT_eSPI (working fine), then LovyanGFX (giving me those errors).

As I’m limited in the length, here is the relevant part of the logfile (note that there are other error that I have not addressed yet) :

Please also answer:

I suspect that you have forgotten a closing bracket or semicolon somewhere when editing your code or have inserted too many. This can lead to error messages being shown later in other header files.

I think I have found were the problem comes from.

As I’m using 2 different boards, I defined 2 “env” sections in the platformio.ini file. As I needed 2 LGFX board config files, I used those lines in the env section of the board 1 and same method for the second board :

build_flags= ... -include [LGFX board 1 (.hpp) header file]

In platformio documentation, it is mentionned that :

-include file : Process *file* as if #include “file” appeared as the first line of the primary source file.

ref.: https://docs.platformio.org/en/stable/projectconf/sections/env/options/build/build_flags.html

But it doesn’t seem to have the same behavior as if I include this line in my main.cpp file directly (this is working fine) :

#include [LGFX board 1 (.hpp) header file]

So, why isn’t building correctly when using the platormio.ini file ?

6

Great that you found the cause of the error! :+1:

I have never used -include.

The documentation says that it has the same effect as #include in the “primary source file”. Question: What is the primary source file in an Arduino project?
Is it the main.cpp from the Arduino core? :thinking: I do not know. :man_shrugging:

So I would always use regular #include statements in my source files.

7

But it would not serve my needs to include it directly. So the problem is not solved.

In fact, I know the file is found using -include in platformio.ini, but the compilation seems to be done in C and not in C++.

@ivankravets and/or @maxgerhardt : could you please help on this please ?

8

If you pass include to the global environment, it will affect related frameworks and libraries. Could you try passing this option to build_src_flags — PlatformIO latest documentation ?

Thank you for your quick reply @ivankravets.

I forgot to mention that the related .hpp and .cpp are under the lib folder, not in the src folder. I guess that build_src_flags would then not be useful ? (unless I didn’t understand)

This line is in the platformio.ini file :

build_flags = ... -include lib/boards/Lilygo-T-Display-S3.hpp

10

I followed your advice and it worked !

		build_src_flags =
			${env.build_src_flags}
			;needed for LovyanGFX (LGFX)
			-include lib/boards/Lilygo-T-Display-S3.hpp

Thank you so much !

@ivankravets I just resumed working on my project. Event if there are no errors anymore while building, I realized that the header file is not added in the main.cpp using build_src_flags. From main.cpp I call a function prototyped in this header file and it is not recognized.

Here are the details : Build option build_src_flags in platformio.ini doesn't work · Issue #1146 · platformio/platform-espressif32 · GitHub

Please provide a simple project to reproduce this issue ( you can put it on Github).
