Building C++ application with pre-build library gives compile errors - c++

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:

My code fragment is as follows:
#include <Poco/Net/HTTPRequest.h>
#include <Poco/Net/HTTPClientSession.h>
#include <Poco/Net/HTMLForm.h>
#include <Poco/StreamCopier.h>
string RTMPAppProtocolHandler::GetAuthPassword(string user) {
INFO("Testing auth: %s", STR(user));
Poco::Net::HTTPClientSession s("www.somehost.com");
//s.setProxy("localhost", srv.port());
Poco::Net::HTTPRequest request(Poco::Net::HTTPRequest::HTTP_GET, "/large");
Poco::Net::HTMLForm form;
form.add(“entry1”, “value1”);
form.prepareSubmit(request);
s.sendRequest(request);
Poco::Net::HTTPResponse response;
std::istream& rs = s.receiveResponse(response);
Poco::StreamCopier::copyStream(rs, std::cout);
return user;
}
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)

Cannot source cpp file after updating xcode and Rstudio in MacOS Monterey

I have made the 'mistake' to update few things in my MacOS Monterey Intel-based and now I cannot source any cpp file as I used to do with Rcpp.
I tried to understand how others have resolved similar issues, but my problem seem to still remain.
Below you can find the error message, which perhaps may help to point me out to the possible solution:

make error: recipe for target 'all-recursive' failed

Hello and thank you for your help in advance (I'm a bit of a newbie). I am on ubuntu 18.
I am trying to install an older version of some software called HepMC (need older version for project) and I had no problem installing the slightly newer version. When I try to build from source I get an error on the make command. I've seen this "all-recurive failed" error all over the web, but the solutions I've seen for other people have seemed to be very software specific and have not helped me.
I am not really sure how to interpret this error and I haven't been able to find a good answer. Any tips or suspicions on what might be going on here would be greatly appreciated. Been bashing my head against this for awhile
Before running make I did
autoreconf -i configure.ac
./configure
and this ran with no errors or warnings.
Here's the snippet where the error seems to begin, I'll attach the full printout from "make" down below.

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:

How to compile a program from .cpp files and a makefile

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
{
protected:
// ...
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.
