|---|
| 54 | <p>The option to link <span class="bold"><strong>Boost.Threads</strong></span> as a static |
|---|
| 55 | library has been added (with some limitations on Win32 platforms). |
|---|
| 56 | This feature was originally removed from an earlier version |
|---|
| 57 | of Boost because <code class="computeroutput"><a href="../thread_specific_ptr.html" title="Class thread_specific_ptr">boost::thread_specific_ptr</a></code> |
|---|
| 58 | required that <span class="bold"><strong>Boost.Threads</strong></span> be dynamically linked in order |
|---|
| 59 | for its cleanup functionality to work on Win32 platforms. |
|---|
| 60 | Because this limitation never applied to non-Win32 platforms, |
|---|
| 61 | because significant progress has been made in removing |
|---|
| 62 | the limitation on Win32 platforms (many thanks to |
|---|
| 63 | Aaron LaFramboise and Roland Scwarz!), and because the lack |
|---|
| 64 | of static linking is one of the most common complaints of |
|---|
| 65 | <span class="bold"><strong>Boost.Threads</strong></span> users, this decision was reversed.</p> |
|---|
| 66 | <p>On non-Win32 platforms: |
|---|
| 67 | To choose the dynamically linked version of <span class="bold"><strong>Boost.Threads</strong></span> |
|---|
| 68 | using Boost's auto-linking feature, #define BOOST_THREAD_USE_DLL; |
|---|
| 69 | to choose the statically linked version, |
|---|
| 70 | #define BOOST_THREAD_USE_LIB. |
|---|
| 71 | If neither symbols is #defined, the default will be chosen. |
|---|
| 72 | Currently the default is the statically linked version.</p> |
|---|
| 73 | <p>On Win32 platforms using VC++: |
|---|
| 74 | Use the same #defines as for non-Win32 platforms |
|---|
| 75 | (BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB). |
|---|
| 76 | If neither is #defined, the default will be chosen. |
|---|
| 77 | Currently the default is the statically linked version |
|---|
| 78 | if the VC++ run-time library is set to |
|---|
| 79 | "Multi-threaded" or "Multi-threaded Debug", and |
|---|
| 80 | the dynamically linked version |
|---|
| 81 | if the VC++ run-time library is set to |
|---|
| 82 | "Multi-threaded DLL" or "Multi-threaded Debug DLL".</p> |
|---|
| 83 | <p>On Win32 platforms using compilers other than VC++: |
|---|
| 84 | Use the same #defines as for non-Win32 platforms |
|---|
| 85 | (BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB). |
|---|
| 86 | If neither is #defined, the default will be chosen. |
|---|
| 87 | Currently the default is the dynamically linked version |
|---|
| 88 | because it has not yet been possible to implement automatic |
|---|
| 89 | tss cleanup in the statically linked version for compilers |
|---|
| 90 | other than VC++, although it is hoped that this will be |
|---|
| 91 | possible in a future version of <span class="bold"><strong>Boost.Threads</strong></span>. |
|---|
| 92 | |
|---|
| 93 | Note for advanced users: <span class="bold"><strong>Boost.Threads</strong></span> provides several "hook" |
|---|
| 94 | functions to allow users to experiment with the statically |
|---|
| 95 | linked version on Win32 with compilers other than VC++. |
|---|
| 96 | These functions are on_process_enter(), on_process_exit(), |
|---|
| 97 | on_thread_enter(), and on_thread_exit(), and are defined |
|---|
| 98 | in tls_hooks.cpp. See the comments in that file for more |
|---|
| 99 | information.</p> |
