I installed package BH in order to have access to boost C++ library. The installation was successful, however when I use the following lines in C++ file:
// [[Rcpp::depends(BH)]]
#include "boost/math/distributions/normal.hpp"
I am getting an error that the file "boost/math/distributions/normal.hpp" cannot be found.
Am I doing something wrong?

I installed Aspose.Cells and tried to write a simple C++ file that includes Aspose.Cells.h. I soon realized that I had to install two other external libraries, boost and icu4c as without these libraries my compiler would throw errors saying some h or hpp files can not be found.
My problem is: even after I installed these libraries, I still couldn’t compile my code, as I received a new error saying “Fatal ERROR: comdef.h: No such file or directory.”
And the error persisted even after I installed the latest version for SDK for Win 10.
My simple file can run if I remove the line "#include Aspose.Cells.h" .
Can someone please enlighten me as to how to solve this error?
Also I noticed there is a folder called “Publish” under “include” folder for Aspose.Cells. This folder is besides boost and icu. Could this mean Publish is the third external library to be installed? But I couldn’t find any library called Public on the web. Pls see the screenshot below.
directory of include folder that comes with the installed Aspose.Cells package
Thanks a lot!
My code is as follows:
#include <iostream>
#include <Aspose.Cells.h>
using namespace std;
int main() {
cout << "hello!!!" << endl;
return 0;
}

Can someone please help me with my issue with Aspose.Cells library for C++?
I was writing my first C++ programme using Aspose.Cells library. Everything seemed smooth except that the following error was produced after I built the file:
Error before I launch is:
"Error exist in a required project.Continue launch?"
Error after running the code is:
"**fatal error: boost/config/compiler/gcc.hpp: No such file or directory**".**
If I commented out the line #<include Aspose.Cells.h>, the file can run with no errors.
I tried to solve the error by installing Boost library for C++ from zip file "boost_1_73_0", as I think Aspose depends on Boost to run. However, I couldn't link to Boost successfully as there doesn't seem to be a "include" folder and "lib" folder for me to add into project properties.
My questions are:
Will installing Boost solve my problem?
If yes, how can I install Boost library successful?
The following is my code in C++. Thanks a Lot in advance!
#include <iostream>
#include <Aspose.Cells.h>
using namespace std;
int main() {
cout << "!!!I am little red!!!" << endl;
return 0;
}

UPDATE: I have successfully installed and linked Boot library now but I have got three warning message upon building: "Ignoring #pragma warning [-wunknown-pragmas]" , are these warning messages serious?
I also ran into another fatal error: unicode/uloc.h:No such file or directory. How can I correctly link up to unilib-master/Unicode library?
Yes, installing Boost helps.
If Aspose only requires header-only libraries from Boost, then you don't have to do much. The "include" path you're looking for is just the folder where you extracted the zip. The actual library headers are under boost/ in that folder, which are then found by the compiler.
If you need the shared libraries, you will need to build them. Follow the steps here Getting Started On Windows
I'm having some troubles to get my CodeLite IDE working with Boost library.
So basically, I've got CodeLite v.6.1.1 and Boost library downloaded from sourceforge. I would love to make it actually working, but I failed to do so using the following concept:
I did create new workspace, than I did go -> Settings -> Build Settings -> Compilers (here I have two compilers, one of which is CodeLite 4.8.1 and the other one is MinGW Code::Blocks, I did select CodeLite 4.8.1. -> Advanced -> Global Paths -> and I did provide two blank lines of Include Path and Libraries Path with the directory of unpacked boost library (Windows 7): C:\boostlib\boost_1_57_0.
In this catalog (i.e.: C:\boostlib\boost_1_57_0), I have got all neccesary files, all of them are unzipped and yet I can't get it working.
Besides, I can't click on apply when I'm done with setting path to files containing boost library, all I can do is click ok but once I'm done with this I can't work with libraries from boost.
The following code isn't working:
#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>
int main()
{
using namespace boost::lambda;
// ERROR MESSAGE: boost/lambda/lambda.hpp, No such file or directory
typedef std::istream_iterator in;
std::for_each(in(std::cin), in(), std::cout << (_1 * 3) << ” ” );
return 0;
}
The message I get is:
boost/lambda/lambda.hpp: No such file or directory
Is there any chance I can get CodeLite working with boost library or should I simply switch IDE and forget about it ?
Your on the right track but need to point to the libs and include folders inside the boost directory.
I use the the http://nuwen.net/mingw.html version of mingw as STL (the guy) includes boost as part of his distribution.
So in codeLite I just have to add
C:\MinGW\lib to the libraries path
C:\MinGW\include to the include path
This is a really basic question because I am a C++ newbie. I want to use the Boost.Interprocess library, but am having trouble building it. I'm trying to follow these instructions, but it's not working for me. Here is what I have:
#define BOOST_DATE_TIME_NO_LIB
#include <boost/interprocess/shared_memory_object.hpp>
#include <iostream>
using namespace std;
int main() {
cout << "Hello, beautiful world!\n";
}
But I get this error:
boost_1_55_0\boost\date_time\gregorian_calendar.hpp(63) : fatal error C1083: Cannot open include file: 'boost/date_time/gregorian_calendar.ipp': No such file or directory
I know Boost is able to load properly, because I can get an example that uses #include <boost/lambda/lambda.hpp> to work just fine. It's just when I try to include the Boost.Interprocess library that I am having trouble. The cause is clearly because it's having trouble including the Boost.DateTime library properly, but according to the documentation (linked above) I should be able to get by without separately compiling Boost.DateTime if I define BOOST_DATE_TIME_NO_LIB, right?
What am I missing here?
You need to add it to the preprocessor
In VS go to - Project >> properties >> C/C++ >> Preprocessor in the 'Preprocessor Definitions' paste BOOST_DATE_TIME_NO_LIB.
You can download boost libraries here: https://www.boost.org/users/download/
After that, you can include them in your projects. Also, you can check this video on how to add boost libraries in eclipse IDE on Ubuntu: https://www.youtube.com/watch?v=gN8zrnWxFeI
I'm new to the boost C++ library and I'm trying to use boost with python. Whenever I compile my simple test program I get an error:
error: pyconfig.h: No such file or dirctory
(followed by thousand more errors which I'm sure are because of this missing header).
I downloaded boost from it's website and then built the library. I still have no idea why that file is missing and how to get it. Please help!
I'm using code::blocks MinGW compiler and I have pointed code blocks to the boost folder as a search directory for headers as well as libraries.
Here's my simple program:
#include <boost/python.hpp>
using namespace boost::python;
int main()
{
Py_Initialize();
PyRun_SimpleString("from time import time,ctime\n"
"print ’Today is’,ctime(time())\n");
Py_Finalize();
return 0;
}
You apparently do not have the CPython headers in your include path. Just having boost::python is not enough, you need Python itself, too.
