GLIB in C programming: No such file or directory

[jenniferruurs]

I a have C file where the
where when I execute it via terminal:

gcc test.c -o test

I get the error
fatal error: glib-object.h: No such file or directory

I also tried

gcc -O2 $(pkg-config --cflags glib-2.0) -o test test.c $(pkg-config --libs glib-2.0)

The headers of the C file

#include <stdlib.h>
#include <stdio.h>
#include <glib-object.h>
#include <json-glib/json-glib.h>

Do you have the developers package for glib 2.0 (libglib2.0-dev) installed ? Just having the library does not give you the headers, they are in the *-dev packages.
Also, 'pkg-config --libs' outputs the '-l' option for the linker-part of the gcc toolchain, it doesn't produce the '-I' option for the preprocessor which gives paths for the headers. You probably want 'pkg-config --cflags --libs glib-2.0' which does both.

How do I install the developers package for glib 2.0?

[Holger_Gehrke]

sudo apt install libglib2.0-dev

in a terminal or with synaptic.

After I installed:

sudo apt install libglib2.0-dev

And I execute

gcc test.c -o test

The first error:
fatal error: glib-object.h: No such file or directory

Changes in to:
fatal error: json-glib/json-glib.h: No such file or directory

Did you install json-glib dev package?

[Holger_Gehrke]

According to https://packages.ubuntu.com json-glib.h is in the package 'libjson-glib-dev'.

After I installed

sudo apt-get install libjson-glib-dev

When I try
gcc test.c -o test

The first error came back:
fatal error: glib-object.h: No such file or directory

When I try

gcc -O2 $(pkg-config --cflags glib-2.0) -o test test.c $(pkg-config --libs glib-2.0)

Changes in to:
fatal error: json-glib/json-glib.h: No such file or directory

You need to tell the compiler where to find the necessary from your newly added package.

gcc -O2 $(pkg-config --cflags glib-2.0 json-glib-1.0) -o test test.c $(pkg-config --libs glib-2.0 json-glib-1.0)

Thank you this did worked!

Is there a way how I can added these files to gcc so that

gcc test.c -o test

Would also work?

Or isn't that possible?
