I am trying to cross compile in eclipse using the arm gcc compiler. I go to projrct , properties and set the c/c++ compile option and set the flag to -mfloat-abi=hard.
It throws the following exception while building:

It builds fine without that flag. But I need to set it for it to run on the beaglebone.Any ideas what I am doing wrong?

I am trying to include a library from Github (https://github.com/dcjones/hat-trie).
The installation worked fine and I was able to add the library
to the linker in Eclipse
but the problem is that I don't know how to use it.
I have added it as a header
#include <hat-trie.h>
but it's giving this error:

Any idea how can I fix this?
I devellop a piece of c++ software on my OpenSUSE, which I like to test on another OpenSUSE system.
I copied the executable file on the other system, but when I am starting it I receive an error:
"error while loading shared libraries: libboost_system.so.1.61.0:
cannot open shared object file: No such file or directory"
How can I compile an independent executable without dependencies?
Eclipse does this:

You need to make sure you have the boost libraries installed on your system, and that the path to them is included in you LD_LIBRARY_PATH variable.
For example, if the libboost_system.so file (or symlink) is to be found at /usr/local/boost-1.56.0/lib64 on your system, then you would run the command.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/boost-1.56.0/lib64`
To find out exactly which libraries you need, you can run the command:
ldd my_binary
The output will tell you exactly which libraries are required, and which of those can't currently be resolved.
I am trying to include boost in building C++ projects on Ubuntu. The g++ version is 4.8.1 and the boost version is 1.57.0. I followed these instructions to use boost (header only libraries). I put the boost library into ~/opt/lib, and when I try to compile the project I get the following error output:

What have I made wrong?
I already read everything Make: *** [] Error 1 and I am returning a 0 in my main method.
I've tried switching up parsers, but that doesn't work either. I've tried the internal build, that doesn't work (and even if it did I want to work with makefile's).
Here's an example of the error being given. I believe this is what's preventing me from creating the binary files which is a must have in order to run my app.

Here's the console bit. I did a refresh and then build.

As you can see from the image, Lab1 has no Binaries and it's showing the make error.
Solution found thanks to guys commenting
I'm including this code as reference to the comments to this question.
/*
* Token.h
*
* Created on: Sep 12, 2013
* Author: cam
*/
#pragma once
class Token {
public:
Token();
virtual ~Token();
enum TOKEN_TYPE {START, MIDDLE, END, ERROR};
/**
* #pre processToken must be ran first!
*/
virtual Token getNextToken(char*);
virtual bool processToken(char*);
};
/*
* Token.cpp
*
* Created on: Sep 12, 2013
* Author: cam
*/
#include "Token.h"
Token::Token() {
}
Token::~Token() {
}
Token Token::getNextToken(char* buff) {
}
bool Token::processToken(char * buff) {
}
Ultimately I wasn't including two virtual method definitions in my base class. While this got it to compile, I'm curious to know why this is necessary as they are defined as virtual.
I have installed minGW and msys. In eclipse CDT I created c++ project that uses cross gcc toolchain.
Eclipse created make file which I can use through command line, so if I run make all project is correctly compiled, but if I use eclipse to build, it fails with following message
**** Build of configuration Debug for project cpp ****

I have chosen wrong toolchain in project, changed to mingw gcc and now it works
