I've used ->| to indicate a tab character, as it's clearer to read than ⇥

Set a target, its dependencies and the commands to execute in order

shell commands are not required. To just list dependencies for a target, use only the first line:

The first target is the default target Eset uninstaller for mac.
This could be all for example, listed together with its dependencies:all: $(TARGET)
Use .PHONY <target> at the start or end of a build step if is not an actual file to be build:

but before is preferred.

Comments are preceeded with #, either at the start of the line, or as end-of-line comments
Lines can be continued across line-breaks by ending a line with a backslash .Just be aware of accidental spaces after the backslash (simply always removing trailing whitespace).
Set a variable with VARNAME = valueVariable values can contains spaces: no need to escape them or quote them. Practical for a list of filenames or compiler flags
Standard variable names:

Use a variable with $(VARNAME): dollar sign and enclosed in parentheses.
Single-letter variables can omit the parentheses. This is mainly done for the automatic variables, see below.
prepend shell commands with '@' to suppress printing the command itself. Shell output is still visible.(The @ character has to be at the beginning of the command, directly after the tab.)
Useful for specific echo commands, e.g.

Parallel builds:make -j to use all available coresmake -j2 to use two cores
Automatic variables
- $@: name of the target
- $<: first dependency

$^: dependencies (prerequisites), separatead by spaces (duplicates are removed)

$+: as $^, but with duplicates included
$?: all prerequisites that are newer than the target (with respect to their timestamp)

Each of the above automatic variables has two variants: appended with a D, or appended with an F.The former results in the directory name of the relevant variable, the latter in just the filename portion.Surround these with parentheses, since they are longer than 1 character, e.g.: $(<F).

functions
GNU make has a bunch of functions that can be applied to variables. A few are listed here, more in the GNU make manual.
- $(dir file1.txt dir/file2.txt) results in ./ dir/.
- $(notdir file1.txt dir/file2.txt) results in file1.txt file2.txt.
The above two functions can be used instead of the D and F additions in case of automatic variables.
- $(suffix file1.txt) yields .txt. Includes the last dot, and omits results (empty result) from files without an extension.
- $(wildcard *.txt) results in a space-separated list with all .txt files.
$% (GNU extension).This is also an automatic variable, but can be used somewhat differently. It is used in patterns:

This will build an object file for each source file, with a matching filename as output.(Note that with most compilers, -o $@ is not really necessary in this case,since the compiler will automatically replace the extension with .o.)

% is written between a prefix and postfix, either of which can be empty.

The actual 'stem' for each match is stored in the $* variable.

If there is no (Unix-style) directory separator '/' in the target name, then only the filename part is matched on; directory names are removed before trying to match.This means that the stem does not contain the directory name, though the final target name and prerequisites do: it's only for the matching.
