[Boost-users] boost1.33.0 on IA64 thread problem

I'm working on porting a large project to IA64. Therefore I'd like to 
use the boost thread package on IA64 using gcc 3.2.3 (standard compiler 
on the SL 3 Linux distribution). There are some problems which I describe 
below and at the end of the mail I pose my questions. Thanks for any 
comments !

To test I use the following code:

#include <stdlib.h>
#include <boost/thread/mutex.hpp>
 int main() {
  boost::mutex   mut;
   return 0;
 }

I downloaded boost 1.33.0 & build & install it. When I try to compile it 
with
g++ -g -O2 -pthread 
-I/opt/boostTest/include/boost-1_33 
-L/opt/boostTest/lib 
-lboost_filesystem-gcc-mt -lboost_thread-gcc-mt -lpthread 
-lboost_regex-gcc-mt prog.c

I get

In file included from 
/opt/boostTest/include/boost-1_33/boost/thread/detail/config.hpp:18,
                 from 
/opt/boostTest/include/boost-1_33/boost/thread/mutex.hpp:15,
                 from prog.c:2:
/opt/boostTest/include/boost-1_33/boost/config/requires_threads.hpp:47:5: 
#error "Compiler threading support is not turned on. Please set the 
correct command line options for threading: -pthread (Linux), -pthreads 
(Solaris) or -mthreads (Mingw32)"
[many more "not declared" messages]

Now I use "-DBOOST_HAS_THREADS", but this also does not help :

g++ -g -O2 -pthread -DBOOST_HAS_THREADS 
-I/op/boostTest/include/boost-1_33 
-L/opt/boostTest/lib 
-lboost_filesystem-gcc-mt -lboost_thread-gcc-mt -lpthread 
-lboost_regex-gcc-mt prog.c
                                                                                           
/usr/bin/ld: cannot find -lboost_thread-gcc-mt
collect2: ld returned 1 exit status

In the boost mailing list archive I found an IA64 patch posted by Ben 
Hutchings. Applying this patch and recompiling boost I get:

g++ -g -O2 -pthread
-I/opt/boostTest/include/boost-1_33
-L/opt/boostTest/lib
-lboost_filesystem-gcc-mt -lboost_thread-gcc-mt -lpthread
-lboost_regex-gcc-mt prog.c

In file included from 
/opt/boostTest/include/boost-1_33/boost/thread/detail/config.hpp:18,
                 from 
/opt/boostTest/include/boost-1_33/boost/thread/mutex.hpp:15,
                 from prog.c:2:
/opt/boostTest/include/boost-1_33/boost/config/requires_threads.hpp:47:5: 
#error "Compiler threading support is not turned on. Please set the 
correct command line options for threading: -pthread (Linux), -pthreads 
(Solaris) or -mthreads (Mingw32)"

But when I use "-DBOOST_HAS_THREADS" everything works fine:

g++ -g -O2 -pthread -DBOOST_HAS_THREADS
-I/op/boostTest/include/boost-1_33
-L/opt/boostTest/lib
-lboost_filesystem-gcc-mt -lboost_thread-gcc-mt -lpthread
-lboost_regex-gcc-mt prog.c

Here are my questions:

Boost 1.33.0 contains the file boost/detail/sp_counted_base_gcc_ia64.hpp, 
nevertheless thread support seems not to work with gcc3.2.3. Thread 
support works by applying the patch and using "-DBOOST_HAS_THREADS". What 
is the status of boost 1.33.0 concerning IA64 ? I guess the patch has not 
been incorporated into the boost distribution ?

On IA32 I can compile and use boost 1.33.0 threads using gcc3.2.3 without 
using "-DBOOST_HAS_THREADS". Why is this the case ? Ideally I would like 
to use the same compiler flags to compile a project using boost on IA32 
and IA64. 

For some reasons I'd prefer to use boost 1.32.0 on IA64 but I could not 
get the thread package to work. Does boost 1.32.0 threads work on 
IA64/gcc3.2.3 ? Or is it only with boost 1.33.0 + patch that I can use 
them on IA64 ?

Best regards,
Andreas
