Boost & Eclipse

[Barnabé Faliu <barnabe.faliu@…>]

Hello everyone, I need your help with a problem in relation with Boost 1-52-0 and Eclipse for C++ developpers. First, i use Cygwin 1.7.17-1 as compiler and my boost library is well compiled (boostrap.sh and b2 executed). My OS is Windows 8 Pro 64bits.

Here is the simple program I try to execute :

#include <iostream>
#include <boost/thread/thread.hpp>
using namespace std;
 
 
int main() {
 
	cout << "hello";
	return 0;
}

This code is compiling without any problem but, when i want to execute it, nothing appears. I noticed that if I set "#include <boost/thread/thread.hpp>" as comment, the word "hello" appears, then I concluded that boost library was the problem, but I absolutly don't know why..

Here are my project linkers :

Includes (Cygwin C++ Compiler) : C:/boost

Libraries : boost_thread

boost_system

Librairies search path : C:/boost/stage/lib

I as well want to precise that I defined the system variable "CYGWIN" with "nodosfilewarning" value because I had an error like that when compiling : "cygwin warning: MS-DOS style path detected: c:/ Preferred POSIX equivalent is: /cygdrive/c CYGWIN environment variable option "nodosfilewarning" turns off this warning. Consult the user's guide for more details about POSIX paths: cygwin.com/cygwin-ug-net/usin...sing-pathnames"

Hope you'll help me, thanks !

Have you tried including another header from another boost library, e.g Boost.System? Maybe you should consult some specific Eclipse forums or StackOverflow.

I think you found something, problem must come from thread library because execution works with every headers except headers from "boost/stage/lib/thread/" and the header "/stage/lib/thread.hpp"

EDIT : Sorry i typed wrong, Pathes are respectively "boost/thread" and "boost/thread.hpp"

I have tried for the first time to use Eclipse and I rich to compile and run

#include <iostream>
//#include <boost/thread/thread.hpp>
using namespace std;

int main() {
	cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
	return 0;
}

When I add the library boost_system and the path where it can be found the build is OK,

**** Build of configuration Debug for project tests ****

make all 
Building file: ../src/tests.cpp
Invoking: GCC C++ Compiler
g++ -I/Users/viboes/boost/trunk/boost -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/tests.d" -MT"src/tests.d" -o"src/tests.o" "../src/tests.cpp"
Finished building: ../src/tests.cpp
 
Building target: tests
Invoking: MacOS X C++ Linker
g++ -L/Users/viboes/boost/trunk/stage/lib -o "tests"  ./src/tests.o   -lboost_system
Finished building target: tests

When I try to run it, I'm getting

dyld: Library not loaded: libboost_system.dylib
  Referenced from: /Users/viboes/Documents/workspace/tests/Debug/tests
  Reason: image not found

It seems that the run is not seen where the libs are located independently of boost_thread.

Please, could you post the error you are getting on the console?

Problem solved by addind "C:/boost/stage/lib" to the Windows Path environment variable !

Thank you for your help

OK. Then there were no issue with Boost.Thread ;-). I close the issue.
