\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\begin{document}
\=a
\end{document}

The PDF file contains the macron accent and the letter a.

The Latin Modern font also contains the right glyph, however,
it's not supported by T1 (or OT1), but L7x font encoding could
be used.
