11.1 Loading the Gnuastro Make functions ¶

To load Gnuastro’s Make functions in your Makefile, you should use the load command of GNU Make in your Makefile. The load command should be given Gnuastro’s libgnuastro_make.so dynamic library, which has been specifically written for being called by GNU Make. The generic command looks like this (the /PATH/TO part should be changed):

load /PATH/TO/lib/libgnuastro_make.so

Here are the possible replacements of the /PATH/TO component:

/usr/local

If you installed Gnuastro from source and did not use the --prefix option at configuration time, you should use this base directory.

/usr/

If you installed Gnuastro through your operating system’s package manager, it is highly likely that Gnuastro’s library is here.

~/.local

If you installed Gnuastro from source, but used --prefix to install Gnuastro in your home directory (as described in Installation directory).

If you cannot find libgnuastro_make.so in the locations above, the command below should give you its location. It assumes that the libraries are in the same base directory as the programs (which is usually the case).

$ which astfits | sed -e's|bin/astfits|lib/libgnuastro_make.so|'
