C - compilation error - c

if I build my program, it gives me many errors and warning. Everything is from compiled highest source file - main.o.

Where can a problem be?
These errors are caused be "-include" command and source file /usr/include/glib-2.0/glib/gregex.h to makefile. But if I remove this command it will give me errors with "undefined reference to ..." ... declarations from glib. Problem will be with using glib. Before I tried (without an effect):
INCLUDES = -I/usr/include/glib-2.0 \
-I/usr/include/glib-2.0/glib
LIBS := -lglib-2.0
Does anyone have the correct makefile commands with glib? Thanks
EDIT: I would like to create a program, which using streamripper for recording internet audio streams.

Everything is from compiled highest source file - main.o
strange thing to compile an object-file again, or to name a source-file like an object-file.
.o normally is what comes from the compilation step with a .c file.

mex file generated by Matlab-coder: how to re-compile

I recently got some of my Matlab code converted to C and it works. However, I would like to make some changes to these mex file and recompile.
So far, I have only worked with simple mex project: usually consisting of two files like this:
Matlab_mex_Testing.m <--- I call mex function from here.
mexcallingmatlab.c
then I can compile using:
mex -g -ldl CFLAGS="\$CFLAGS -std=c99" -largeArrayDims mexcallingmatlab.c
However, the converted project has multiple *.c, *.o files and when I tried to compile only the ...._mex.c, I get following error:

Makefile and program structure Raspberry Pi GCC

I' m trying to setup a simple tool to measure different aspects of a system. I build a project which can log an accelerometer, gyroscope and a magnetometer. I want full control of the the program so I decided not to use any usr/local kind of libraries and keep all files in the project folder. All files all working. I want to make the structure of my program as follows: https://www.dropbox.com/s/59s3si8spvkdq98/filestructure.png (not enough REP). I don't have much experience in making Makefiles, except changing a few variables. I work in the Embedded environment and mostly with IDE's.
I tried building my project with the following Makefile:
# Project name
NAME = TEST
# Tools
CC = gcc
CFLAGS = -o
# Paths
DRV_PATH = drivers
SRC_PATH = src
LIB_PATH = libs
# includes
INCLUDES = -I $(DRV_PATH) -I $(LIB_PATH) -I $(SRC_PATH)
# what files do we need to compile?
# libraries
MY_LIB = $(LIB_PATH)/bcm2835.c
# main files
MAIN = main.c
# src files
#MY_SRC = $(SRC_PATH)/vector.c
MY_SRC += $(SRC_PATH)/dcm.c
# select drivers to compile
DRV_SRC = $(DRV_PATH)/adxl345.c
DRV_SRC += $(DRV_PATH)/itg3200.c
DRV_SRC += $(DRV_PATH)/hmc5883l.c
DRV_SRC += $(DRV_PATH)/gy-85.c
DRV_SRC += $(DRV_PATH)/nrf24l01.c
# bundle files
ALL_SRC = $(MY_LIB) $(DRV_SRC) $(MY_SRC) $(MAIN)
OBJ = $(ALL:.c=.o)
BIN = $(ALL:.c=)
# make commands
all:
$(CC) $(CFLAGS) $(NAME) $(ALL_SRC)
debug:
$(CC) $(CFLAGS) $(NAME) $(ALL_SRC) -DDEBUG=1
imudebug:
$(CC) $(CFLAGS) $(NAME) $(ALL_SRC) -DIMUDEBUG=1
nrfdebug:
$(CC) $(CFLAGS) $(NAME) $(ALL_SRC) -DNRFDEBUG=1
I use the different make commands to generate some debug output.
The config file currently includes all files and is as follows:
#ifndef CONFIG_H
#define CONFIG_H
/* includes */
#include <stdio.h>
#include <math.h>
/* libs */
#include <bcm2835.h>
/* drivers */
#include "gy-85.h"
#include "adxl345.h"
#include "itg3200.h"
#include "hmcl5883l.h"
#include "nrf24l01.h"
/* src */
#include "dcm.h"
#endif // __CONFIG_H__
And the dcm.h file looks as follows. I tried t keep all .h files like this:
#ifndef DCM_H
#define DCM_H
#include <bcm2835.h>
#include <stdio.h>
#include <math.h>
#include "gy-85.h"
double pitch, roll, yaw;
double DCM_Matrix[3][3];
uint64_t stamp;
void resetFusion(void);
#endif
This is my make result:

You don't have your includes in your rule
INCLUDES = -I $(DRV_PATH) -I $(LIB_PATH) -I $(SRC_PATH)
This just seems to dangle. Simplest solution to my eyes is to move down your CFLAGS definition and add in the includes:
INCLUDES = -I $(DRV_PATH) -I $(LIB_PATH) -I $(SRC_PATH)
CFLAGS = -o $(INCLUDES)
This way you don't have to change anything else. Of course, there are alternatives, this one just looks easiest.

vtdNav.h and in transcoder.h
and now it compile.
I'm sorry to have put a post to ask how to compile the examples. I have compiled them by modifying the makefile already present in ximpleware_2.11_c and in this way works:

Compiling XFCE4 panel plugin

I am converting a gnome panel applet to xfce panel plugin. I have so far removed the few gnome specific parts in the source and replaced them with xfce specific source as appropriate.
I created makefile.am and configure.ac files using templates such as the weather plugin and the example plugin. However I am unsuccessful in getting it compiled properly. I am probably missing something obvious, but I double checked the examples with my own files and found no obvious problems.
I have attached the appropriate files as well as output of the errors in the hope someone has an idea. I don't think the problem is in the actual source, but I can add some of that later if necessary.
Errors while compiling:

From example_applet.c which is the first source file entered. Originally I only had "xfce4_my_example_plugin_SOURCES = example_applet.c" since the rest would be found through that file. It gave the same error.

XFCE_PANEL_PLUGIN_REGISTER_EXTERNAL(example_applet_fill);
It looks like I solved the problem. The build process for xfce is slightly different than what I am using to build the gnome panel applet.
For the gnome applet I use one source file to include all other source and header files.
In xfce it appears, after having looked over various plugin source trees, each source file includes the necessary headers, however none of the source files include other source files.
The fix was to not include any other source files at all and change each source file to include the header files.

compiling csapp.c and csapp.h

I am trying to compile the files csapp.c and csapp.h on a Ubuntu 12 operating system. I think I am missing some header file or some option but I do not know which one. Or perhaps I do not have the latest gcc. Here is my Makefile:
SRC = tiny.c
LIB = csapp.c
INC = csapp.h
ALL = $(SRC) $(LIB) $(INC)
webServer-gcc : $(ALL)
gcc -std=c99 -O2 -lpthread -lrt -o server $(ALL)
Here is my error output from the terminal:

Here is my last remaining error inside my main function:

here is line 23 of my code:

Use -std=gnu99, see this link.
and I write a new Makefile for you, hope this can help you.
CC = gcc
LIBS = -lpthread -lrt
INCS = -I./
CCFLAGS = -std=gnu99 -O2
all: server
server: csapp.o tiny.c
$(CC) $(CCFLAGS) $^ -o $# $(LIBS) $(INCS)
csapp.o: csapp.c csapp.h
$(CC) $(CCFLAGS) -c $< -o $# $(INCS)
clean:
rm -f server csapp.o
