failure in building Lyra about lyra HOT 5 CLOSED

Thank you. when upgrading gcc to 8.4.0 problem solved.

from lyra.

Yes, C++17 is definitely needed. Have you tried passing a compiler option to set the standard library?.

from lyra.

Also, let us know how you are calling bazel build. The standard should be set automatically to -std=gnu++17 from the .bazelrc file.

Hi,

Thank you for the pointer. I was somehow missing the .bazelrc file.
After downloading a clean version, most errors have been resolved. There is still this error
that I am not sure how to handle:

That seems like an error compiling a C++7 header file, not part of the Lyra library.
