Sometime yesterday most of the regression tests that I run (not the incremental ones?) started crashing and not sending any results. The screen output is the general error: "No such file or directory: '/home/tomkent/teeks99-02/a/results/boost/bin.v2/libs/any/test/any_test.test'" Looking at the tail of the results/bjam.log file shows this: error: at /home/tomkent/teeks99-02/a/tools_bb/kernel/modules.jam:107 error: Unable to find file or target named error: 'has_float128.cpp' error: referred to from project at error: '../libs/multiprecision/config' That was on Ubuntu 12.04, running the gcc-4.6 tests, but the others (including windows) have the same error. I don't believe anything else changed on the machines that were running the regression tests. You can still see the previous results on the regression results page. Tom Kent
