[odb-users] Strange Problems Building ODB Compiler From Source

[Brian Coggins]

Could you try replacing the above two gxx_name
assignments with the following and see if that helps:

if ($cxx.target.cpu    == $build.host.cpu && \
    $cxx.target.system == $build.host.system)
{
  gxx_name = $recall($cxx.path)
  gxx_name = $regex.replace($gxx_name, '\\', '\\\\') # Escape back slashes.
}
else
  gxx_name = g++

That fixed it!  It builds fine, and the resulting odb executable works correctly.  Many thanks!

Brian

Ok, looks like the compiler is targeting an older version of the
runtime than what you are running. I guess we need to relax the
comparison a bit. Could you try replacing the above two gxx_name
assignments with the following and see if that helps:

if ($cxx.target.cpu    == $build.host.cpu && \
    $cxx.target.system == $build.host.system)
{
  gxx_name = $recall($cxx.path)
  gxx_name = $regex.replace($gxx_name, '\\', '\\\\') # Escape back slashes.
}
else
  gxx_name = g++
