[Help-gsl] Linking GSL [noob]

[Fg Nu]

Hello all,

Earlier today, I posted a question to Stack Overflow
http://stackoverflow.com/q/12968355/1414455

but did not get an appropriate response. I believe this has to do with a basic 
misunderstanding of the linking process. 

1) For example, here is "fitting2.c" from the "/doc/examples/" folder and it 
has the include directives

//--------------------------------------------------------------------------------------
#include <stdio.h>
#include <gsl/gsl_multifit.h>
//--------------------------------------------------------------------------------------


Since my GCC installation lives in 
"E:\programming\c\libraries\gsl-1.15.tar\gsl-1.15", I changed the directive to 

//--------------------------------------------------------------------------------------
#include <gsl-1.15/multifit/gsl_multifit.h>
//--------------------------------------------------------------------------------------


 My first question is that is this the correct way to include the header file? 
When I compile it with gcc, I obviously get a linking error:
gcc -Wall fitting2.c
gcc -Wall fitting2.c
fitting2.c:2:44: fatal error: gsl-1.15/multifit/gsl_multifit.h: No such file or 
directory
compilation terminated.

2) I then created a makefile for this as follows

#============================================
CC=gcc
CFLAGS=-c -Wall -IE:/programming/c/libraries/gsl-1.15.tar/
LDFLAGS= -LE:/programming/c/libraries/gsl-1.15.tar/
LIBS= -lgsl
SOURCES=fitting2.c
OBJECTS=$(SOURCES:.c=.o)
EXECUTABLE=fitting2

all: $(SOURCES) $(EXECUTABLE)

$(EXECUTABLE): $(OBJECTS)
    $(CC) $(LDFLAGS) $(OBJECTS) $(LIBS) -o $@

.c.o:
    $(CC) $(CFLAGS) $< -o $@
#============================================

but this terminated with the following error

make
gcc -c -Wall -IE:/programming/c/libraries/gsl-1.15.tar/   -c -o fitting2.o 
fitting2.c
process_begin: CreateProcess((null), gcc -c -Wall 
-IE:/programming/c/libraries/gsl-1.15.tar/ -c -o fitting2.o fitting2.c, ...) 
failed.
make (e=2): The system cannot find the file specified.
make: *** [fitting2.o] Error 2

I am not sure what I am doing wrong exactly.

I am using GCC 2.7.0 (MinGW) on 64-bit Windows.

Thanks.
