I am trying to run a simulation but I keep getting some kind of error. I am not an expert on C++, but I think it's due to header file include. I am getting the following error:
error: ISO C++ forbids declaration of ‘type name’ with no type [-fpermissive]
void OutInterest(Ptr<const ns3::ndn::InterestHeader> interestHeader,Ptr<const ns3::ndn::Face> face) {
^
../scratch/vndn_simulation.cc:87:52: error: template argument 1 is invalid
void OutInterest(Ptr<const ns3::ndn::InterestHeader> interestHeader,Ptr<const ns3::ndn::Face> face) {

void OutInterest(Ptr<const ns3::ndn::InterestHeader> interestHeader,Ptr<const ns3::ndn::Face> face) {
Any idea on how to solve this error?
It says here:
class NameComponents;
^
In file included from ./ns3/ndn-v2v-net-device-face.h:31:0,
from ../scratch/vndn_simulation.cc:15:
./ns3/ndn-header-helper.h:34:21: note: ‘ns3::ndn::NameComponents’ has a previous declaration here
typedef Name NameComponents;
^
that you cannot forward declare NameComponents because the compiler has already seen that it is a typedef and not a class.

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.
According to the docs, Mac should be supported but when attempting to build iotivity some headers are used that I think are posix specific.

➜ iotivity git:(master) ✗
I'm following the instructions at https://wiki.iotivity.org/macosx_build_instructions pointed to by https://wiki.iotivity.org/build_for_your_system
had a look but can't see any flags that'd enable mac support explicitly. Anyone know if this is actually supported and just been broken in recent commits? I building master checked out two days ago.
There is a windows-port branch but no mac named branches. remotes/origin/1.3-rel has the same issue.
Found this https://stackoverflow.com/a/24947106/400048 which lead me to my assertion about the posix specific headers being used.
So, anyone know if this can be built on mac and if so, how?
It's not an "officially supported" platform or target at this point, I gather its health was better in the past. Some people have had decent luck building for Mac, I have not. Changes to improve it will certainly considered, and there's an opening for a "Mac port maintainer" to make sure it doesn't rot again (and there's a github project which has added Mac buildability along with other build system reorgs - but I believe compared to iotivity that's rather out of date - however one could start picking fixes from there: https://github.com/OpenOCF/iochibity)
I recently downloaded a program. A patient specific survival prediction CLI, http://pssp.srv.ualberta.ca/
The readme included states:
"1 Compilation
The code should compile on Linux without any modification. To compile, just type ’make’. There should
be 2 executables after compilation, mtlr train and mtlr test."
I download an extracted the folder to my location, when I go into the directory and type make I get:

I looked up the basic packages needed for compiling c++ code, as well as basics on how to run it and none have gotten me past this issue. It looks as if it has a problem with size_t not having a type.
The start of DenseVector.cpp is :
#include "DenseVector.h"
#include <cassert>
#include <iostream>
DenseVector::DenseVector(size_t n): m_dim(n)
{
m_dvector.reserve(n);
for (size_t i=0; i<n; i++)
{
m_dvector.push_back(0);
}
}
I have never compiled code like this before, so I am probably missing something obvious. If its needed I am running ubuntu 14.04, g++ version is
4.8.4.
Thanks
It sounds like the README lied. Probably it happened to work with a different version of the standard library.
Try adding
#include <stddef.h>
near the top of DenseVector.h.
Open the file DenseVector.h in the root directory of the program and modify it, inserting
#pragma once
#include <vector>
#include <cstddef> // <--- Add this line to the file
class DenseVector

Save it and try again!
I don't think you are using the correct version of C; I think you need C11. Instead of using the -03 flag, use -11 or -std=c11. Then recompile it.
From http://cppcms.com/wikipp/en/page/cppcms_1x_forms,
According to this,
A declaration introduces one or more names into a program.....
Therefore, classes, structures, enumerated types, and other
user-defined types can be declared for each compilation unit
AFAIK, constructor should be in myapp.cpp, while declaration should be in content.h. So I put
There are 5 fields on the form. In CppCMS, the form built using 3 codes (the 4th codes are restriction for the fields)
1st codes:
name.message("Your Name");
sex.message("Sex");
marital.message("Marital Status");
age.message("Your Age");
submit.value("Send");
2nd codes:
add(name);
add(sex);
add(marital);
add(age);
add(submit);
3rd codes:
sex.add("Male","male");
sex.add("Female","female");
marital.add("Single","single");
marital.add("Married","married");
marital.add("Divorced","divorced");
4th codes, are restriction for the fields:
name.non_empty();
age.range(0,120);
I'm quite confused which one should be declaration
------------------added
I've tried add all above codes in myapp.cpp like below:
class myapp : public cppcms::application {
public:
myapp(cppcms::service &srv) : cppcms::application(srv)
{
dispatcher().assign("",&myapp::info_form,this);
mapper().assign("");
}
void info_form()
{
name.message("Your Name");
sex.message("Sex");
marital.message("Marital Status");
age.message("Your Age");
submit.value("Send");
add(name);
add(sex);
add(marital);
add(age);
add(submit);
sex.add("Male","male");
sex.add("Female","female");
marital.add("Single","single");
marital.add("Married","married");
marital.add("Divorced","divorced");
name.non_empty();
age.range(0,120);
}
};
But it still giving error:

Add the following defines:
g++ -DHAVE_NETINET_IN_H -DHAVE_INTTYPES_H ...
Or add #include <stdint.h> before including Thrift.h in your code.
See the discussion at THRIFT-1326. The issue is suppposedly fixed in thrift 0.9.
It looks like your problem is a compiler issue.
It can't find the type "uint32_t"
There is another question on SO regarding this:
'uint32_t' identifier not found error
Quoted from user templatetypedef
This type is defined in the C header which is not currently
a part of the C++ standard. According to the Wikipedia page on the
header, it hasn't shipped with Visual Studio until VS2010.
In the meantime, you could probably fake up your own version of the
header by adding typedefs that map Microsoft's custom integer types to
the types expected by C. For example:
typedef __int32 int32_t; typedef unsigned __int32 uint32_t; /* ...
etc. ... */ Hope this helps!
