Re: Please, please help!!!

Your error message indicates that exceptions are disabled. Try not disabling them. I think some versions of GCC might disable exceptions by default based on the language its compiling for -- e.g., if it's invoked as 'gcc' or the filename extension designates a C file. I didn't see

Hi Steve, Thanks a lot for the info. I saw that but did not know exceptions were disabled in some compilers by default, which as you suggested, I found out this one does. I enabled them, and now it compiles. I have another question for you if I may. I attempted to simply stream the numbers to the standard output but it complains that there is no operator defined for this object. Is there a file I can include that contains the overloaded output operator functionality? I am sure this must be available, I am just not sure of its location. I know that ublas uses the file "IO" in order to bring those definitions in. Again, thanks for everything and have a good one!

behaviour under Cygwin, though.

I can get it to compile under Cygwin just by adding the Boost include with -I and defining __linux__ with -D.

HTH, -Steve

Hi Steve, Thanks again for the help. I did that and now the file is recognized, but I am receiving the following error upon compilation:

In file included from main.cpp:3: /usr/include/c++/3.2/boost/libs/random/random_device.cpp: In member function `void boost::random_device::impl::error(const std::string&)': /usr/include/c++/3.2/boost/libs/random/random_device.cpp:92: exception handling disabled, use -fexceptions to enable gmake: *** [main.o] Error 1

The program is the same except now I am including #include .

Thanks again!

There is a source file under the libs/random directory that contains the implementation of random_device. You'll have to include it in your project in order to link.

boost::random_device

...

...

...

Hello all,

I am attempting to use the non-deterministic

random number generator

...

...

...

class contined in boost::random and have

encountered the following

...

...

...

errors upon running the program. The program does

compile without

...

...

...

errors, and I am using KDevelop 2.1.3 in the

RedHat Linux 8.0

...

...

...

environment.

Here's the offending code:

#include <iostream> #include <cstdlib> #include

int main() { boost::random_device dev;

return EXIT_SUCCESS; }

I receive the following error message: /home/JAgiato/boosttest/boosttest/main.cpp:6:

undefined reference to

...

...

...

`boost::random_device::default_token' /home/JAgiato/boosttest/boosttest/main.cpp:6:

undefined reference to

...

...

...

`boost::random_device::random_device[in-charge](std::basic_str

...

...

...

ing

const&)'

...

...

...

/home/JAgiato/boosttest/boosttest/main.cpp:8:

undefined reference to

...

...

...

`boost::random_device::~random_device

[in-charge]()'

...

...

...

My goal is to use this class to produce

non-deterministic 32 bit

...

...

...

integers which will be streamed to a binary file.

Any help is greatly

...

...

apprechiated! Thank you!
