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.
