I have a CMake C++ project which targets mac, which has a .h header file that includes the following import.
#import <Foundation/Foundation.h>
When I try to build the project, I get the following compiler error:

I've tried updating the project's CMakeLists.txt to pass `"-framework Foundation" but somehow CMake filters out that library from the build.
Does anyone know what might be the root cause, and how to fix it?

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 am new to vein and omnet++. I followed this tutorial http://veins.car2x.org/tutorial/ everything works up to step 3, for some reason veins 4.7 doesn't build in omnet++ 5 (IDE) and generates the following errors.

I am also using sumo_win64_0.32.0. I am not sure what causes these errors.
Any help is greatly appreciated.
The issue has been fixed in this pull request and a new minor revision of Veins (i.e. Veins 4.7.1) has been released. Please download the new version to get the fix and also some additional improvements.
I just encountered that error as well and here is what happens:
The compiler cannot resolve the enum class definitions in TimerManager.h as there is a name ambiguity with the macros RELATIVE and ABSOLUTE within wingdi.h
enum class StartMode { RELATIVE, ABSOLUTE, IMMEDIATE };
enum class EndMode { RELATIVE, ABSOLUTE, REPITITION, OPEN };
Quick fix is to rename the occurrences in TimerManager.h and TimerManager.cc to something else. E.g. Replace all occurrences of RELATIVE with RELATIVEINS and ABSOLUTE with ABSOLUTEVEINS etc... (or whatever you like). Worked fine for me with 4.7 and OMNet++ 5.2.1.
A patch is required to make Veins 4.7 compile with OMNeT++ 5.3 for Windows. The cleanest way may be something like on https://pastebin.com/ymzqMpEF
- enum class StartMode { RELATIVE, ABSOLUTE, IMMEDIATE }
+ enum class StartMode { relative, absolute, immediate }
that is, renaming the all-uppercase enum class constants to lower case ones (something recommended by many coding styles as well).

Problem description
I compiled TensorFlow source code for Python & C++ API bindings following the steps shown in http://www.blitzblit.com/2017/06/11/creating-tensorflow-c-headers-and-libraries/ (We have to take into account that this tutorial is not updated). After compiling the TF source code I include the TF library in the C++ project:
#include <tensorflow/core/public/session.h>
Finally, I compile the C++ project (Until here everything seems fine). Then, when I try to launch the C++ code I get the following message:
/Applications/CLion.app/Contents/bin/cmake/bin/cmake --build /Users/arcadillanzacarmona/Desktop/FaceSDK/ cmake-build-debug --target FaceSDK -- -j 2

Can anyone help me? Seems that the main problem is in the google/protobuf.
The problem is that gif_lib.h and that protobuf header file are incompatible. More specifically, the problem is that gif_lib.h uses the preprocessor to define a macro called VoidPtr, and then the protobuf header uses VoidPtr as an identifier. The fault firmly lays with gif_lib, not protobuf! Preprocessor macros, by convention, are usually uppercase, should include the library name, and should be avoided entirely if possible (in this case, wouldn't a typedef have done?).
Here are some possible workarounds:
Include the protobuf header (or something that includes it, like a TensorFlow header) before the gif_lib.h one (or, again, something that includes it).
After including gif_lib.h, write #undef VoidPtr on a separate line (but this might cause other mysterious problems, depending on how gif_lib.h is implemented.
Do not #include those both of those two headers from any one of your files; hide them behind your own interfaces.
File a bug with whoever wrote gif_lib and get them to stop using the proprocessor in such a dangerous way.
Use a better designed library in place of gif_lib.
I had the similar issue which is solved by changing compiler and using a different version of C++(i.e. from clang to g++-5, g++-7, etc.). I suggest that you can try to solve it in this way. Sorry for not able to give a direct solution.
For the error about nsync_cv, alc1218's solution on this post may help, which is changing the file mutex.h as follows:

but the included Topology.h does contain

How to resolve?
EDIT:
Adding forward declaration for class Topology gives further error:

Basically the project has four main compilation problems:
Circular include dependency between TopologyFactory and Topology classes.
Including TString.h header directly when is meant to be used as a typedef.
Missing cstdlib/cstdio includes.
Member initialization in class definition (not available until C++11).
The fix for the first one involves removing TopologyFactory from the Topology header, thus breaking the circular include dependency. Then including the TopologyFactory header where is needed.
The second one is easy to fix: just remove the TString header includes so it uses the definition at Utils/Types.h by default.
Third fix is trivial: just add the cstdio/cstdlib includes where needed.
The last fix involves moving the static initialization to the definition file (maybe the author was using an old compiler with an extension who allowed this type of initialization).
I made a patch on this gist so you can see the changes. The project compiles with g++ 5.2.1 on Ubuntu 15.10.
There is a cross-reference in the code.
Topology.h includes TopologyFactory.h and vice versa TopologyFactory.h included Topology.h
The most easy way to fix it add forward declaration for class Topology into TopologyFactory.h:
#ifndef TOPOLOGYFACTORY_H
#define TOPOLOGYFACTORY_H
...
class Topology;
class TopologyFactory
{
More correct approach would be try to solve these dependencies, i.e. don't include TopologyNetwork.h in Topology.h and then in all cpp files which using TopologyNetwork and Topology add two include directives:
/*
source file DesineModel.cpp for class: DesineModel
...
*/
...
#include "Network/Topology.h"
#include "Network/TopologyFactory.h"
...
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)
