Arrow above = symbol - Code ok in overleaf, ko in Texmaker

Question

I have the following code which works in overleaf, but doesn't work in texmaker:

\documentclass{article}
\usepackage{graphicx,mathtools}
%*
\usepackage{old-arrows}
\newcommand{\eqstackrel}[1]{\stackrel{\substack{\mathclap{#1}\[0.5ex]\displaystyle\uparrow\ ~}}{ = } }
%*
\newcommand{\equparrow}[1][1]{\stackrel{\text{\scalebox{1}[#1]{$\uparrow$}}}{=}}
\newcommand{\equparrowx}[2][1]{\stackrel{\mathclap{#2}}{\equparrow[#1]}}
\begin{document}
\begin{align}
b&=a/c\[-.5\baselineskip]
a&\equparrow b\[-.5\baselineskip]
a&\equparrow[2] \frac12
\end{align}
[a\equparrowx{a=b/c}b]
[a\equparrowx[1.5]{a=b/c}b]
[a \equparrowx[2]{a=\frac{b}{c}} b]
%*
[ a\eqstackrel{b = a/c} b ]
%*
\end{document}

The error in the log is:

!pdfTeX error: pdflatex (file oasy10): Font oasy10 at 600 not found
==> Fatal error occurred, no output PDF file produced!

How can I fix it?

Hello @StevenB.Segletes do you mean that I cannot use it in Texmaker? — Gennaro Arguzzi, Sep 21 '21 at 18:01
I don't have texmaker. But the fact that it works in another installation perhaps indicates it is not a package deficiency, per se. More likely, something is out of date in your installation, though it might be peculiar to all texmaker installs. — Steven B. Segletes, Sep 21 '21 at 18:13
@StevenB.Segletes I remember that some time ago it worked also in texmaker on another PC — Gennaro Arguzzi, Sep 21 '21 at 18:20

The package old-arrows has been added to TeX Live on August 25, 2015.

You don't tell what version of TeX Live is used by your TeXmaker program, but judging from the error message, the package has been installed improperly: besides the old-arrows.sty file, also the fonts have to be installed in the expected places and map files have to be updated.

Check your file system against the list below. In particular, look for oasy.map.

package:     old-arrows
category:    Package
shortdesc:   Computer Modern old-style arrows with smaller arrowheads
longdesc:    This package provides Computer Modern old-style arrows with smaller arrowheads, associated with the usual LaTeX commands. It can be used in documents that contain other amssymb arrow characters that also have small arrowheads. It is also possible to use the usual new-style Computer Modern arrows together with the old-style ones.

If your TeX distribution is MiKTeX, be sure to update the font maps as an administrator as well as a user. See How can I update font map files in User mode?

Hi @egreg thank you a lot for the explanation. I'm using Texmaker 5.0.4 — Gennaro Arguzzi, Sep 22 '21 at 10:07
@GennaroArguzzi This has nothing to do with the version of Texmaker, but with the release of TeX Live you have on the machine. Open the log file of your test and report the first line, please. — egreg, Sep 22 '21 at 10:10

A way to solve the problem is to comment the command:

\usepackage{old-arrows}
