This isn't really a very useful bug report, but in any case I think this is not a bug in tempo2 but some issue with your build environment. It looks like there is a problem with libdl or glibc, or some version conflict between them. This might be caused if you have installed some custom compiler or something?

Thank you, I use command “export LIBS=-ldl && ./configure“ to make it, and it works well

[Michael Keith]

Looks like the issue was resolved.
