| 10 | patched: boost_1_55_0/boost/smart_ptr/detail/lwm_pthreads.hpp
|

|

| 15 | patched: ilona.pbp
|

| 16 | changes: only builds ilona static/sharable objects including

| 38 | - Both systems do have identical component configuration (check
|

| 39 | both boost logs).
|
|---|
| 40 | - Both system have no issues when building the boost library
|
|---|
| 41 | including the test application;
|
|---|
| 42 | - The files created in the stage/lib for both boost build differ,
|
|---|
| 43 | on aix also libboost_atomic.a is created;

| 59 | =======
|

| 60 | Build boost 1.55 on AIX71, only change with build#1 is that compiler

|

| 77 |
|

| 78 |
|
|---|
| 79 | CONCLUSION: when BOOST_THREAD_DONT_USE_ATOMIC is defined no build/runtime errors occur.
|
|---|
| 80 | Internally in boost file smart_ptr/detail/lwm_pthreads.hpp is not used anymore.
