The following discussion is from [KiCad/fedora-packaging] Handle ambiguous Python shebang (#20).  I'm cross-posting to kicad-developers since I'm not sure who sees the fedora-packaging emails.  Please don't hate me. :-)

According to the log, we have errors in io_benchmark.cpp:

undefined reference to `IFSTREAM_LINE_READER::IFSTREAM_LINE_READER(wxFileName const&)'
undefined reference to `STDISTREAM_LINE_READER::ReadLine()'
undefined reference to `IFSTREAM_LINE_READER::Rewind()'
undefined reference to `STDISTREAM_LINE_READER::~STDISTREAM_LINE_READER()'

This _might_ be due to b88121e377b7244519715b604bd50026b2af440e (Add an in-memory STREAM_LINE_READER benchmark), which is the only commit I see in 2018 that touches io_benchmark.cpp.  Or it could be something that changed in a Makefile.  I am not knowledgeable enough to determine that.

For reference, here is the full text of the error log.  It also mentions qa_utils/stdstream_line_reader.h, which appears to be part of the same issue:
