(Try 3 at getting accepted by the mailing list) All- I just noticed that there was an issue causing regression runs to fail on both develop and master: the results end with this: boost-test(RUN) "math/test_autodiff_8" : "libs/math/test/test_autodiff_ 8.cpp" boost-test(COMPILE) "math/diff_autodiff_incl_test" : "libs/math/test/compile_test/diff_autodiff_incl_test.cpp" boost-test(COMPILE) "math/diff_finite_difference_incl_test" : "libs/math/test/compile_test/diff_finite_difference_incl_t est.cpp" boost-test(COMPILE) "math/diff_lanczos_smoothing_incl_test" : "libs/math/test/compile_test/diff_lanczos_smoothing_incl_t est.cpp" error: Unable to find file or target named error: 'my_autodiff_reverse_test.cpp' error: referred to from project at error: '../libs/math/test' In trying to figure out how long this had been happening, I went to the website(s) to see when the last good runs were, but pulling up those, it appears that the job that parses the results into the website hasn't been running since mid-june! https://regression.boost.io/master/developer/summary.html https://regression.boost.io/develop/developer/summary.html I had been happily running these runners for over a decade, even though they don't match the immediate feedback that a library author gets from a github actions job, running across *a lot* of different compilers seems useful, but apparently no one cares? Frankly (and obviously), I haven't spent as much time on care and feeding of the runners as I have in the past. It mostly comes down to rebooting the machines every couple months and updating to new gcc/clang/vs versions when they appear. **I'm looking for feedback from the community:** Let it go, not worth the electricity spent on running these (maybe move the infrastructure to github runners?) -or- Hey this could be useful, let's spend a couple cycles getting it back working again. Thanks, Tom
