I am learning the book "Advanced Linux programming" and have got two problems:

Thay are in lines

and

in the Makefile of page 253.

2. Where is the command 'mtrace'
I can't find this command on my Redhat 8.0 personal system.

$^ The names of all the prerequisites, with spaces between them.
$< The name of the first prerequisite.

Look in the make info pages, they explain it all.
Type "info make" or "pinfo make" to see them.

Never heard about it. There are tools named strace
and ltrace.

mtrace is a malloc trace. There seems to be a port to Linux, if google
serves me right.

It's a perl script included with glibc. It just sets up the malloc
included in glibc to trace memory allocation and output leaks.
It may not be installed by all distributions though. In SuSE it is part
of glibc-devel.

Using valgrind is probably better.

On RH6 mtrace is part of glibc, that is, it will always be installed.
Perhaps "info libc" contains infomation about it.
