RE: [Boost-Users] Please, please help!!!

4 Apr 2003


      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 this
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,

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!

boost::random_device
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!
