I'm using PlatformIO to compile my ESP8266 (ESP12e) with Arduino framework. At a certain point, I'm getting errors if I use #include in a certain order.
Below is simplified my code:
platformio.ini
[env:esp12e]
platform = espressif8266
board = esp12e
framework = arduino
upload_speed = 460800
Teste.h
//#include <cstdlib> //<<--this
#include <cstring> //<<-- and/or this causes error!
#include <Arduino.h>
#include <map>
Teste.cpp
#include "Teste.h"
void setup() {}
void loop() {}
Output
$ pio run

Did I miss something? Maybe a bug in Arduino Framework or Espressif SDK?
The <Arduino.h> header defines max and min macros. It really shouldn't do that. To get around the problem, add
#undef max
#undef min
right after your #include <Arduino.h> line.

Hi stackoverflow community,
I am trying to get a project leveraging Tensorflow Lite Micro to run on my ESP32 using PlatformIO and the Arduino framework (not ESP-IDF). Basically, I followed the guide in this medium post https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7 and then included everything in my already existing ESP32 project.
My project was compiling fine prior to the integration of Tensorflow Lite Micro but since integrating it, I am getting the following compile errors which seem to be related to the Tensorflow framework itself. When I uncomment everything related to Tensorflow, it compiles fine. But just when only including the following header files, it breaks:
#include "tensorflow/lite/micro/kernels/micro_ops.h"
#include "tensorflow/lite/micro/micro_error_reporter.h"
#include "tensorflow/lite/micro/micro_interpreter.h"
#include "tensorflow/lite/micro/micro_mutable_op_resolver.h"
#include "tensorflow/lite/schema/schema_generated.h"
#include "tensorflow/lite/version.h"
Does someone know where these errors come from and what I can do to solve those?
Here is the error trace:

Today I faced a similar problem. I solved it by using TensorFlowLite_ESP32 library instead of Arduino_TensorFlowLite. You need to download this library and add the line #include <TensorFlowLite_ESP32.h>. I hope this helps you too
I resolved this for now by switching from the Arduino framework to the ESP-IDF framework. With this, it works like a charm.
I defined a map like this :
std::map<std::string,LexType> lexname_s = { { "PROGRAM" , PROGRAM}}
And a LexType, like this :
typedef enum
{
ENDFILE, ERROR,
PROGRAM, PROCEDURE, TYPE, VAR, IF,
} LexType;
In Visual Studio Code, it always shows error type when I touch it.
//
I add more details for what i said.
the line
std::map<std::string,LexType> lexname_s = { { "PROGRAM" , PROGRAM}}
show error . it seems i can't initialize it in this way.
I compile it in the gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) in a cloud server which is centos7.
AND the error code shows below
from parse.cpp:1:
../utils.h:52:27: error: invalid conversion from ‘int’ to ‘const LexType&’ [-fpermissive]

EOF(which shows in the map define) is a reserved a macro defined in stdio.h
it's the problem of it.
change the name will be ok.
I'm trying to compile my legacy-free libFoundation project, located at https://github.com/chmeeedalf/lf-foundation but running into problems using clang 3.4 and libc++. It appears something is not happy with ARC in the containers, and I see the following error excerpt:

The file in this example has a std::vector declared as:
std::vector<id> items;
Can someone shed some light onto this problem? I tried adding an explicit __strong in the std::vector declaration, to no avail, however __unsafe_unretained does eliminate the error.
I'm building on FreeBSD -CURRENT, using the libc++ and clang 3.4 that is in base.
Answering my own question, in case others are interested. Clang defines __weak as a preprocessor macro for ARC. However, FreeBSD's <sys/cdefs.h> also defines __weak itself. The workaround I found for this was to add to my local <sys/cdefs.h>:
#ifndef __weak
#define __weak what_freebsd_defines_ass
#endif
I am trying to modify a C++ program by including POCO to be able to do a HTTP request and receive a result. Basically, I just need within another C++ program to give a username and password and get a plain "OK" or "ERROR" response.
I am not familiar with C++ at all (use Java mainly). I build the POCO project and installed it without any problems, but when I add it to the project I get a while pile of compiler errors when building:

Am I doing something stupid? It is only this little interaction with a HTTP server which I need to modify, so I am just looking for a very simple solution but find it hard to find something that works easy (mainly because I am not familiar with C++ though)
I'm trying to compile this program and I'm having trouble finding the following files online:

You seem to have some mistake in the #include directive, boost libraries are usually included as
#include <boost/whatever.hpp>
or
#include <boost/module/header.hpp>
Or if the boost libraries were not installed to your include paths and it is present in the current directory:
#include "boost_1_46_1/boost/..."
Rules for the filename are as said above
Read the docs for more info
