Mktemp can be built either using the included “configure” script or using the cmake utility. The instructions below only describe using the “configure” script.

Mktemp’s “configure” script has a large number of options that control its behavior and enable or disable optional functionality. Be sure to read this document fully before configuring and building mktemp. You may also wish to read the file INSTALL.configure which explains more about the “configure” script itself.

To build mktemp from the source distribution, you need a POSIX-compliant operating system (any modern version of BSD, Linux, or Unix should work), an ANSI/ISO C compiler and the make utility.

For most systems and configurations it is possible simply to:

1. If you previously ran “configure” on a different host you will probably want to do a “make distclean” to remove the old “config.cache” file. Otherwise, “configure” will complain and refuse to run. Alternately, you can simply “rm config.cache”.

2. “cd” to the source or build directory and type “./configure” to generate a Makefile and config.h file suitable for building mktemp. Before you actually run configure you should read the “Available configure options” section to see if there are any special options you may want or need.

3. Type “make” to compile mktemp.

4. Type “make install” (as root) to install mktemp and its manual page. You can also install various pieces the package via the install-binaries and install-man make targets.

This section describes flags accepted by the mktemp’s “configure” script. Defaults are listed in brackets after the description.

--cache-file=FILE
Cache test results in FILE

--help
Print the usage/help info

--no-create
Do not create output files

--quiet, --silent
Do not print "checking..." messages

--prefix=PREFIX
Install architecture-independent files in PREFIX.  [/usr/local]

--exec-prefix=EPREFIX
Install architecture-dependent files in EPREFIX. [same as prefix]

--bindir=DIR
Where the mktemp executable will be installed.  [EPREFIX/bin]

--mandir=DIR
Install man page in DIR [PREFIX/man]

--srcdir=DIR
Find the sources in DIR [configure dir or ..]

--with-CC=path
Specifies path to C compiler you wish to use.

--with-incpath
Adds the specified directories to CPPFLAGS so configure and the
compiler will look there for include files.  Multiple directories
may be specified as long as they are space separated.
Eg: --with-incpath="/usr/local/include /opt/include"

--with-libpath
    Adds the specified directories to LDFLAGS so configure and
    the compiler will look there for libraries.  Multiple
    directories may be specified as with --with-incpath.

--with-libraries
    Adds the specified libaries to LIBS so mktemp will link
    against them.  If the library doesn't start with "-l" or
    end in ".a" or ".o" a "-l" will be prepended to it.  Multiple
    libraries may be specified as long as they are space
    separated.

--with-man
When installing the manual page, install the one in man(7) format.

--with-mdoc
When installing the manual page, install the one in mdoc(7) format.

--with-random=path
Mktemp with use "path" as the path to a device from which to read
random data.  This defaults to "/dev/urandom" if it exists.

--with-prngd=path|port
For systems without a random device, the prngd and egd daemons can
be used as an entropy source.  The argument to this option should
either be the path to a Unix domain socket or an IP port number.
