Linker error to UnscaledCycleClock on Alpine

[benstadin]

I'm trying to compile a library on Alpine (musl) which compiles just fine on Ubuntu. I'm getting a linker error as show below, though I cannot relate that to the actual abseil library (I mean any other than libabsl_base.a).

The build fails as follows:

testing check_audience_test...
Error loading shared library libjwt_verify.so: No such file or directory (needed by tests/check_audience_test)

ldd output for my library:

Can you provide a complete reproduction? If I had to guess, check that location of the Abseil libraries is in your runtime linker search path.
