Hi Andy, I think the problem is that you aren't telling GCC that you are compiling multi-threaded code. Try: g++ -pthread -c test.cpp Then: g++ -pthread test.o ../boost/stage/lib/libboost_thread-gcc-mt.a Maybe that will help, Good Luck, - Dave On Mon, 2007-04-23 at 17:56 -0400, Venikov, Andy wrote:

Hi all,

recently I had to move from Mandrake to RedHat linux.

On the new system, a simple thing like this crashes:

<------- test.cpp

#include

void * Thread1() {

//sleep some time

return 0; }

int main(int, char**) { boost::thread thread1(Thread1); thread1.join();

return 0; }

-------->

The crash happens in the create_pthread call in boost::thread constructor.

Here's the build command:

g++ -c test.cpp

g++ test.o ../boost/stage/lib/libboost_thread-gcc-mt.a -lpthread

Outuput of g++ --version:

g++ (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)

Output of uname -a:

Linux joe.rps.local 2.6.9-34.ELsmp #1 SMP Fri Feb 24 16:54:53 EST 2006 i686 i686 i386 GNU/Linux

Everythink worked fine on Mandrake.

I followed exactly the same steps to build boost on the new system….

Thanks,

Andy.
