Most of the options to configure (which are to do with building) are similar for every program which uses this script. Here the options that are particular to Gnuastro are discussed. The next topics explain the usage of other configure options which can be applied to any program using the GNU build system (through the configure script).
(=INT) If this option is given an integer value, that value
will be used for the default number of threads to use. If it is not
given, then the total number of threads will be read from the system,
see Threads in GNU Astronomy Utilities. Specifying
--with-numthreads=no or --without-numthreads is
equivalent to not calling this option it at all.
Only build and install progname along with any other program that is enabled in this fashion. progname is the name of the executable without the ast, for example imgcrop for ImageCrop (with the executable name of astimgcrop). If this option is called for any of the programs in Gnuastro, any program which is not explicitly enabled will not be built or installed.
Do not build or install the program named progname. This is very similar to the --enable-progname, but will build and install all the other programs except this one.
Enable checks on the GNU Portability Library (Gnulib). Gnulib is used
by Gnuastro to enable users of non-GNU based operating systems (that
don’t use GNU C Library or glibc) to compile and use the advanced
features that this library provides. We make extensive use of such
functions. If you give this option to $ ./configure, when
you run $ make check, first the functions in Gnulib will be
tested, then the Gnuastro executables. If your operating system does
not support glibc or has an older version of it and you have problems
in the build process ($ make), you can give this flag to
configure to see if the problem is caused by Gnulib not supporting
your operating system or Gnuastro, see Known issues.

Note: If some programs are enabled and some are disabled, it is equivalent to simply enabling those that were enabled. Listing the disabled programs is redundant. |
Note that the tests of some programs might require other programs to
have been installed and tested. For example MakeProfiles is the first
program to be tested when you run $ make check, it provides
the inputs to all the other tests. So if you don’t install
MakeProfiles, then the tests for all the other programs will be
skipped or fail. To avoid this, in one run, you can install all the
packages and run the tests but not install. If everything is working
correctly, you can run configure again with only the packages you want
but not run the tests and directly install after building.
