#To Compile

To run the GLIB examples you require the Library glib-2.0.

One of the pain points of C is linking libraries and using them, so how do we get glib into our project the simple recommended way is to use pkg-config like so

gcc `pkg-config --cflags --libs glib-2.0` -o ex-compile ex-compile.c

To fully understand getting the library we can link it using the common -l approach.

We can can use pkg-config to find the locations and the dependent libraries required to get the library imported.

pkg-config will commonly be installed, but on a mac if not use

brew install pkg-config

Then you can search for the required library paths and header paths to compile your example with the required glib-2.0 library. This does the equivalent of the command above specifying the --cflags --libs part.

$ pkg-config --cflags glib-2.0
-I/usr/local/Cellar/glib/2.56.0/include/glib-2.0 -I/usr/local/Cellar/glib/2.56.0/lib/glib-2.0/include -I/usr/local/opt/gettext/include -I/usr/local/Cellar/pcre/8.44/include
$ pkg-config --libs glib-2.0
-L/usr/local/Cellar/glib/2.56.0/lib -L/usr/local/opt/gettext/lib -lglib-2.0 -lintl -Wl,-framework -Wl,CoreFoundation

Then the results of these two commands can be used as so

gcc ex-compile.c -o compile -lglib-2.0 -lintl -I/usr/local/Cellar/glib/2.56.0/include/glib-2.0 -I/usr/local/Cellar/glib/2.56.0/lib/glib-2.0/include

A nice example of very basic interaction with ElasticSearch via Rest and libCurl with C.

You will find code examples and solutions for programming pearls in the relevant directories.

To run:

gcc <filename> -o <wanted-name>
