Hi Mikael, Thanks for your advice and patience!
I checked the lib directory of HPX and it is correct. Also Thanks to Wei, he mentioned that I did not specify " -DPHYLANX_WITH_EXAMPLES=ON " when building Phylanx. After I add this line and rebuild Phylanx, that assertion error is gone. Many thanks!

The old enum value for runtime_mode_console is the same as the new value for runtime_mode_local. Could you please check that you don't accidentally have e.g. the lib directory of an old HPX install in `LD_LIBRARY_PATH` (or that ldd on the executable shows the libhpx.so you expect it to show). If that doesn't show anything building phylanx in a docker container would be useful to rule out a bug on the HPX side. If you can reproduce it in the container it's most likely an HPX bug, otherwise it's most likely your environment. ________________________________ From: [email protected] <[email protected]> on behalf of Nanmiao Wu <[email protected]> Sent: Friday, June 26, 2020 4:46:15 AM To: [email protected] Subject: Re: [hpx-users] Possible HPX errors Hi Mikael, Thanks for the detailed solutions! When I run the test with "--hpx:debug-timing-log", I see "creating local runtime" on the second line. I add "auto rt = hpx::get_runtime()" at the top of hpx_main, but still got that error. I did not get this error in April 14th and could run it successfully at that time. But right now, I got this error every time I ran it. Actually, I am not sure that whether the error is due to my local Linux setting since my friend who uses Windows can run it successfully...

That unfortunately does not help... There are two other simple things you can try before going all-in with debugging. The first is to run the test with "--hpx:debug-timing-log" (ironically this seems to hang, I'll try to fix that independently). You should see on the second line "creating distributed runtime" or "creating local runtime". Let me know which one. The second is to check if adding "auto rt = hpx::get_runtime()" at the top of hpx_main also hits an assert or if it works fine. Beyond that you can try putting a break point on this line: https://github.com/STEllAR-GROUP/hpx/blob/291736b9538afed58269dd1611fd71b8ea839f1f/src/runtime_distributed.cpp#L1483<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FSTEllAR-GROUP%2Fhpx%2Fblob%2F291736b9538afed58269dd1611fd71b8ea839f1f%2Fsrc%2Fruntime_distributed.cpp%23L1483&data=02%7C01%7Cwnanmi1%40lsu.edu%7C9dc506c115a0407cf33208d819c5b687%7C2d4dad3f50ae47d983a09ae2b1f466f8%7C0%7C0%7C637287684282808116&sdata=Q1IgxgpCwDO9W0hlzZRNST5wFKyOdDk3QENS3%2Fsk3xI%3D&reserved=0>. That should be executed before you enter hpx_main on the worker thread where hpx_main gets executed. Running with --hpx:threads=1 might make it a bit easier. Does the assert fire every time you run the test? ________________________________ From: [email protected] <[email protected]> on behalf of Nanmiao Wu <[email protected]> Sent: Wednesday, June 24, 2020 3:49:55 PM To: [email protected] Subject: Re: [hpx-users] Possible HPX errors Hi Mikael, Thanks for your help!
