I can't link glew with xcode. I have glew library is located in /usr/local/lib/libGLEW.dylib
When i compile file in command line all right:
g++ /usr/local/lib/libGLEW.dylib -framework OpenGL main.cpp
But when i compile in xcode, i get error:
'GL/glew.h' file not found
Code:
#include <iostream>
#include <GL/glew.h>
int main(int argc, const char * argv[])
{
// insert code here...
std::cout << "Hello, World!\n";
return 0;
}
Im linked glew with xcode

Adding the library only handles the binary linking. You need to configure Xcode so it can also find the headers describing the contents of the binary.
In Xcode Project Settings search for: Header Search Paths
Add the path to the headers for GLEW (probably near the same folder as the library maybe /usr/local/include). Change the import to match. It should be #include <glew.h> (or #include <GL/glew.h>) if the path gets setup correctly.
For Xcode beginners, here is a screenshot:

I'm learning how to build a simple UI in C++ on my Mac (OS 11.6) using Xcode.
As first step I'm compiling the "Hello world" program, my problem is that the build on Xcode fails but write my own command from terminal, instead, works.
This is the program, I'm using SFML :
#include <iostream>
#include "SFML/Graphics.hpp"
int main(int argc, const char * argv[]) {
// insert code here...
std::cout << "Hello, World!\n";
return 0;
}
I have no error here but when launching Run from Xcode this is the output, in Graphics.hpp file :
#include <SFML/Window.hpp>. //'SFML/Window.hpp' file not found
#include <SFML/Graphics/BlendMode.hpp>
#include <SFML/Graphics/CircleShape.hpp
//other header files
This is how the project is structured ("TestGui" is the project name) :
-TestGui.xcodeproj
-TestGui(folder)
--SFML(directory with all headers file available
-- main.cpp
SFML source code here
So I tried to compile it with my own hands from terminal with :
g++ main.cpp -I ./SFML -o main
and
clang++ main.cpp -I ./SFML -o main
In both cases it compiled, also run worked.
Since the error is linked to a file not found I tried to tell it where libraries are located, so in Xcode from Product->Scheme->Edit Scheme->Run->Arguments->Arguments passed on launch : added -I ./SFML. But the error is still alive.
Added SFML folder to targets from Xcode, didn't copy-pasted but maybe I did it wrong, this is my first time.
EDIT : SFML folder:
--SFML
--- many .hpp files
--- 5 folders (Audio, Graphic, Network, System and Window)
I tried to add also this argument : -L ./SFML but nothing.
I have installed Qt using Macports. However, I do not know how to link Qt into the code ... what is the exact command to compile the code, the include path, library path and the name of the library. Could any one help me with this? I use clang and g++ as the main C++ compiler.
#include <Qdebug>
#include <iostream>
int main()
{
cout << "Test compilation.";
return 0;
}
I am on a Mac OSX and I am trying to start using the C ftdi drivers I installed using brew
brew install libftdi
That installed the library in the directory /usr/local/Cellar/libftdi/1.2 And I have the following C++ code
#include <iostream>
#include <ftdi.h>
using namespace std;
int main() {
struct ftdi_context ftdi;
ftdi_init(&ftdi);
cout << "Hello World" << endl;
return 0;
}
How should I compile this to make it work? I am including the include/ directory so the compiler can find the header file but I do not know which object file should be linked. I am trying to using the following command
g++ -I /usr/local/Cellar/libftdi/1.2/include/libftdi1/ /usr/local/Cellar/libftdi/1.2/lib/libftdi1.a test.cpp
But I am getting bad linker errors even though I have included the .a file. The lib/ directory has the following contents
cmake
libftdi1.2.2.0.dylib
libftdi1.2.dylib -> libftdi1.2.2.0.dylib
libftdi1.a
libftdi1.dylib -> libftdi1.2.dylib
pkgconfig
Is there something else I should try and link it to? Even if you are not aware of this particular driver is there something in general that I should be doing for drivers like this that I have not done?
Thanks for the help!
not particularly good with this kind of stuff I have managed to install the Boost C++ library and this basic program works with the g++ compiler and linking to the right .dylib files.
#include <iostream>
#include <boost/filesystem.hpp>
using namespace boost;
int main()
{
filesystem::path path1("/Users/username/Documents/testfile.txt");
filesystem::remove(path1);
std::cout << "It worked" << std::endl;
return 0;
}
Now I would like to do the same, just using Xcode to build and run the program, but it doesn't work. I have done everything in this tutorial:
http://buddypanda.com/?p=10
i.e. include header and library search paths, as well as linked the .dylib files of filesystem and system under the 'Build Phases' tab.
The Build succeeds but then the program crashed with an error of EXC_BAD_ACCESS.
I can maybe provide more specifics on what goes wrong if you tell me where to look.
Thanks!
EDIT1: I am using g++-4.9 and Boost-1.58 and Xcode 6.4
Hi I am having trouble configuring an Eclipse C++ (32bit) project to use libcurl. I am using MinGW. I am on a 64bit windows OS. I have done the following so far:
Add "libcurl.lib" to the project's Libraries
Add the path of libcurl.lib to the Library Paths
Add the path to the curl header files to the Includes path
In source, I included "curl/curl.h"
However, I am seeing the following message:
Info: Internal Builder is used for build
g++ "-LC:\\projectsrc\\Network\\curl-7.34.0-win32\\lib" "-LC:\\projectsrc\\Network\\curl-7.34.0-win32\\dlls" "-LC:\\projectsrc\\Network\\curl-7.34.0-win32\\bin" -o TestLibCurl.exe "src\\TestLibCurl.o" "-lC:\\projectsrc\\Network\\curl-7.34.0-win32\\lib\\libcurl.lib"
c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot find -lC:\projectsrc\Network\curl-7.34.0-win32\lib\libcurl.lib
collect2.exe: error: ld returned 1 exit status
Below is the sample source
#include <stdio.h>
#include <curl/curl.h>
#include <curl/easy.h>
#include <string>
#include <sstream>
#include <iostream>
using namespace std;
int main()
{
cout << "test" <<< endl;
return 0;
}
Below is a screenshot of where I added the include path and the library file:
For your reference, I have uploaded my sample C++ eclipse project to dropbox here:
https://www.dropbox.com/s/2jowlkz6qypqe9g/TestingLibCurl.zip
The project file includes main.cpp, the libcurl.lib file, the libcurl header files, and the eclipse project setting files (.cproject, .project, .settings)
Oddly, I am able to get this to work in CodeBlocks IDE, using the same MinGW and using the same computer (Windows 64 bit). Do I need to add linker/options/flags when using Eclipse IDE?
