| 30 | I have been attempting to understand the differences between compilers | |
| 31 | and environments when running tests on Boost Phoenix. | |
| 32 | </p> | |
| 33 | <div class="itemizedlist"><ul class="itemizedlist" type="disc"> | |
| 34 | <li class="listitem"> | |
| 35 | Some environments are limited in the memory available for testing and | |
| 36 | I have broken some large tests into smaller pieces. | |
| 37 | </li> | |
| 38 | <li class="listitem"> | |
| 39 | Some of the problems experienced in testing are specific to particular | |
| 40 | compilers being used. | |
| 41 | </li> | |
| 42 | <li class="listitem"> | |
| 43 | Some problems have occurred with several more recent compilers. | |
| 44 | </li> | |
| 45 | <li class="listitem"> | |
| 46 | One problem is that I do not have access to all of the compilers used | |
| 47 | in the tests or by users. | |
| 48 | <div class="itemizedlist"><ul class="itemizedlist" type="circle"> | |
| 49 | <li class="listitem"> | |
| 50 | My system is <a href="http://www.ubuntu.com/" target="_top">Ubuntu </a> | |
| 51 | 12.04 | |
| 52 | </li> | |
| 53 | <li class="listitem"> | |
| 54 | I have expanded the compilers I have available to include the | |
| 55 | following | |
| 56 | </li> | |
| 57 | <li class="listitem"> | |
| 58 | <a href="https://gcc.gnu.org" target="_top">gcc </a> 4.6, 4.8.2, 4.9.0 | |
| 59 | & 4.9.2 (I will add 5.0 when released) | |
| 60 | </li> | |
| 61 | <li class="listitem"> | |
| 62 | <a href="http://clang.llvm.org" target="_top">Clang </a> 3.4, 3.5 & | |
| 63 | 3.6 (pre-release in the last case) | |
| 64 | </li> | |
| 65 | </ul></div> | |
| 66 | </li> | |
| 67 | <li class="listitem"> | |
| 68 | The most difficult problems to diagnose have been some which occur | |
| 69 | when the compilation uses optimization. | |
| 70 | <div class="itemizedlist"><ul class="itemizedlist" type="circle"> | |
| 71 | <li class="listitem"> | |
| 72 | Some of the boost tests use optimization but most do not. | |
| 73 | </li> | |
| 74 | <li class="listitem"> | |
| 75 | It is not usually documented which tests are optimized. | |
| 76 | </li> | |
| 77 | <li class="listitem"> | |
| 78 | This means that a lot of tests run there which fail when optimized. | |
| 79 | </li> | |
| 80 | <li class="listitem"> | |
| 81 | This has made the identification of the cause of the problems | |
| 82 | more difficult. | |
