Unable to statically link thread lib on ia64.

[tomasz.wilk@…]

An attempt to statically link thread library on Itanium (ia64) platform generates the following error:

libboost_thread-vc100-mt-gd-1_41.lib(tss_pe.obj) : error LNK2003: gp relative fixup to symbol not in short data section '_tls_used' LINK : fatal error LNK1165: link failed because of fixup errors

I was able to verify this issue using boost 1.37 with vc8 compiler as well as boost 1.41 with vc10 beta2

The workaround is to force dynamic linking using

#define BOOST_THREAD_DYN_DLL

which is not always acceptable.

Here is a sample program:

#include<stdio.h>

//#define BOOST_THREAD_DYN_DLL
#include<boost/thread.hpp>

void threadBody()
{
	printf("hello from thread");
	boost::this_thread::sleep(boost::posix_time::seconds(5));
}

int main(void)
{
	printf("Hello world!");

	boost::thread myThread(threadBody);
	myThread.join();

	return 0;
}

This is similar in nature to #4258 - #4258 reports this problem only on mingw.

The _tls_used stuff is there to ensure correct cleanup of the per-thread data structures used by boost.thread. I do not know how to fix this for IA64.

Since what is there is broken at the moment, I could remove it entirely, and leave it to users to define boost::tss_cleanup_implemented(), and ensure that boost::on_thread_exit is called when every thread exits.

IA64 is not a tested platform, so this is not a "showstopper"

In the absence of a complete fix, I propose to either force BOOST_THREAD_DYN_DLL with this platform (which should be the define to test?) or as suggested by Anthony "leave it to users to define boost::tss_cleanup_implemented(), and ensure that boost::on_thread_exit is called when every thread exits."

Which option is OK for you?

Moved to wontfix as there is no response from the PO.
