/usr/bin/ld: cannot find -lioutil in Makefile - c

I want to do makefile as the following, but I received this error:

The comment # must ALSO be indented via a <tab> otherwise the recipe never performs the third line
Also, the syntax is a bit obsolete suggest:

for the first line of the recipe
However, regarding your question:
Is there actually a library file named libioutil.so in the directory:
/usr/local/image/lib/sgi

Make file in C giving fatal error

I am trying to create a makefile in C but i am facing some issues.
I have my main .c, one .c which keeps the functions implementations and one .h which keeps the functions declarations.
When i try to run the makefile, i get a fatal error.
here is my makefile:
INCL = prog.h
SRC = prog.c prog_fun.c
OBJ = $(SRC:.c=.o)
EXE = prog
CC = gcc
CFLAGS = -c
RM = rm -rf
all: prog
prog: prog.o prog_fun.o
gcc -o prog prog.o prog_fun.o
prog.o: prog.c
gcc -c prog.c
prog_fun.o: prog_fun.c prog.h
gcc -c prog.c
clean:
$(RM) $(OBJ) $(EXE)
The error i get is this:
gcc -c prog.c
prog.c:11:19: fatal error: prog.h: No such file or directory
compilation terminated.
Makefile:17: recipe for target 'prog.o' failed
make: *** [prog.o] Error 1
Can anyone please help me with this?
What you are trying to do by using this
prog_fun.o: prog_fun.c header.h
It should be only
prog_fun.o: prog_fun.c
Modify your make file as
xyz#xyz-PC:~$ vi makefile
INCL = header.h
SRC = prog.c prog_fun.c
OBJ = $(SRC:.c=.o)
EXE = prog
CC = gcc
CFLAGS = -c
RM = rm -rf
all: prog
prog: prog.o prog_fun.o
gcc -o prog prog.o prog_fun.o
prog.o: prog.c
gcc -c prog.c header.h
prog_fun.o: prog_fun.c
gcc -c prog_fun.c header.h
clean:
$(RM) $(OBJ) $(EXE)
next run it
xxyz#xyz-PC:~$ make
gcc -c prog.c header.h
gcc -c prog_fun.c header.h
gcc -o prog prog.o prog_fun.o
I hope it will work now and make sure indention is correct(not manual spaces, it should be tab key)

Syntax for setting paths to library and compiler in makefile

I am trying to compile a program and I have to set the paths to the NETCDF inc and lib directories in the Makefile as well as set the gfortran and c compiler settings. The variables were already named as shown below, it just told me to edit the paths/options which I have tried to do. Here is what I have for my netcdf inc and lib, as well as the hdf5:
NETCDFINC = -I$(NETCDFF_INCDIR) -I$(NETCDFC_INCDIR)
NETCDFLIB = -Wl,-rpath=$(NETCDFF_LIBDIR) -L$(NETCDFF_LIBDIR) -Wl,-
rpath=$(NETCDFC_LIBDIR) -L$(NETCDFC_LIBDIR) -Wl,-rpath=$(HDF5_LIBDIR) -
L$(HDF5_LIBDIR) -lhdf5_hl -lhdf5 -lz
Note that the NETCDFLIB is on one line on my file, and the paths of the variables are correct, but the syntax may not be.
Next for the fortran and c compiler information I have the following:
FC = gfortran -m64 -g -O0 -ffixed-line-length-132 -Wunused -Wuninitialized
CC = gcc
CFLAGS = -m64 -c -g -I. -DLONG32 -DUNDERSCORE -DLITTLE -Wunused -
Wuninitialized
Finally, when I run the program I first get a bunch of warnings such as:
oban_namelist.f90:495.29:
real :: flt
1
Warning: Unused variable 'flt' declared at (1)
Followed by a bunch of undefined reference errors such as:
oban.o: In function `check':
/uufs/chpc.utah.edu/common/home/zpu-
group3/dhodges/DART/data/radar/opaws/oban.f90:1902: undefined reference to
`__netcdf_MOD_nf90_strerror'
The error shouldn't be in this oban.o function since I didn't write it. The only things I have edited in the program I listed above for the netcdf path and gfortran/c information and so I think the error lies there. This is my first question on here, so if I missed anything you need feel free to ask. What can I try?
Edit: By request, this is the entire makefile I am using. Also, I just type 'make' to compile it per the instructions in the README file.

The problem was solved by editing the NETCDFLIB line as follows:
I edited the NETCDFLIB line as follows and it works: NETCDFLIB = -Wl,-
rpath=$(NETCDFF_LIBDIR) -L$(NETCDFF_LIBDIR) -Wl,-rpath=$(NETCDFC_LIBDIR) -
L$(NETCDFC_LIBDIR) -lnetcdff -lnetcdf -lm -Wl,-rpath=$(HDF5_LIBDIR) -
L$(HDF5_LIBDIR) -lhdf5_hl -lhdf5 -lz
Basically I just needed to add:
-lnetcdff -lnetcdf -lm
This allowed for the compiler to get access to the libraries it needed that were originally undefined.

Trying to use matlab's libmat.dll, but the compiler doesn't recognize the function from the library

I am trying to use matlab libmat.dll in a C application. To compile my C application I use MinGW, for now I use matlab exemple "matcreate.c" and try to compile it, so the projects consist of only one file : main.c .
Here is the makefile I use :
MATINCLUDE = "C:\Program Files\MATLAB\R2010a\extern\include"
MATLIBRARY = "C:\Program Files\MATLAB\R2010a\bin\win64"
#
CC = gcc
LD = gcc
CFLAGS = -O3 -Wall
LFLAGS = -Wall -O3
LIBS = -I$(MATINCLUDE) -L$(MATLIBRARY)
#
PROG = matTest
LISTEOBJ = \
main.o
.c.o :
$(CC) -c $(CFLAGS) $(LIBS) -o $# $<
all : $(PROG)
$(PROG) : $(LISTEOBJ)
$(LD) -o $(PROG) $(LFLAGS) $(LISTEOBJ) $(LIBS)
clean :
rm -f *.obj
Here is what I get in the console
E:\Users\Desk\Dropbox\matTest>make
gcc -c -O3 -Wall -I"C:\Program Files\MATLAB\R2010a\extern\include" -L"C:\Pr
ogram Files\MATLAB\R2010a\bin\win64" -o main.o main.c

collect2.exe: error: ld returned 1 exit status
make: *** [Hello_world] Error 1
Why do I have "undefined reference to matOpen'" and "undefined reference to mxCreateDoubleMatrix" ?? those function are declared in mat.h. and I added #include "mat.h" to the begining of main.c
thank you
Looks like you have included the path to the matlab library, but not the library itself. You need to add a -l<libraryname> to your link line.

compiling C project with makefile

I have a directory called reliability:
ls reliability
analyze.c appl.sh constr.c creer.c greedys.c Makefile
Now I want to install and compile it:
First of all the content of Makefile is:
CC = gcc
CFLAGS = -g -Wall -pthread
SRCS = constr.c creer.c analyze.c greedys.c
PROG = constr creer analyze greedys
all: $(PROG)
constr: constr.c
$(CC) $(CFLAGS) -o constr constr.c
creer: creer.c
$(CC) $(CFLAGS) -o creer creer.c
analyze: analyze.c
$(CC) $(CFLAGS) -o analyze analyze.c
greedys: greedys.c
$(CC) $(CFLAGS) -o greedys greedys.c
clean:
rm -f $(PROG)
When I start compiling it:
make -f Makefile
The error occurs:
gcc -g -Wall -pthread -o constr constr.c
/tmp/cca4NKQl.o: In function `main':
/home/t1/Desktop/reliability/constr.c:89: undefined reference to `exp'
/home/t1/Desktop/reliability/constr.c:89: undefined reference to `exp'
/home/t1/Desktop/reliability/constr.c:89: undefined reference to `pow'
/home/t1/Desktop/reliability/constr.c:89: undefined reference to `log'
collect2: ld returned 1 exit status
make: *** [constr] Error 1
I pass these errors by adding -lm to gcc,
Even when I change CFLAGS from Makefile to CFLAGS = -g -Wall -pthread -lm there is also that error.
My question:
Should I compile all .c programs separately now?
Thank you I really need help,
UPDATE
When I compile creer.c there is an error:
creer.c:39:10: warning: unused variable ‘val2’ [-Wunused-variable] creer.c:38:7:
warning: unused variable ‘val’ [-Wunused-variable]
Part of creer.c is:
void values(){
int val;
double val2;
FILE *fp;
fp = fopen("instances","r");
fseek(fp,0,SEEK_SET);
if(fscanf(fp,"%d",&p)==EOF){printf("EOF\n");}
if(fscanf(fp,"%d",&m)==EOF){printf("EOF\n");}
if(fscanf(fp,"%d",&K)==EOF){printf("EOF\n");}
if(fscanf(fp,"%lf",&lambda_com)==EOF){printf("EOF\n");}
if(fscanf(fp,"%d",&num_inst)==EOF){printf("EOF\n");}
if(fscanf(fp,"%d",&boundl)==EOF){printf("EOF\n");}
if(fscanf(fp,"%d",&boundp)==EOF){printf("EOF\n");}
fclose(fp);
}
You need to add that linker option -lm to the end of your command line.
Do something like this:
LDFLAGS=-lm
...
constr: constr.c
$(CC) $(CFLAGS) -o constr constr.c $(LDFLAGS)
Or you could define a pattern rule:
%: %.c
$(CC) $(CFLAGS) -o $# $< $(LDFLAGS)
and use it to replace all those rules for constr, creer, and so on.

Your makefile is, I'm afraid to say, completely broken.
The basic Makefile syntax is:
target: pre-requisite(s)
<tab>Stuff to do to build target from pre-reqs (if required)
So this is wrong, eg1.o can't be a pre-requisite for building itself.
compile:eg1.o
gcc -o eg1.o
You should have:
eg1.o: eg1.c
gcc $(INC_DIR) -o $# -c $^
($# is the target, $^ all the pre-reqs.)
Then you can:
myexe: eg1.o
gcc $(INC_DIR) $(LIBS_DIR) -o $# $^ $(LIBS)
This will produce myexe from eg1.o. And your all rule should be all: myexe, with no recipe (no commands), and at the top as you have it.
Then you've got your include directories and library directories mixed up. -I is for include paths, -L for library paths.
Place your variable definitions before the rules, that's more common/usual. And don't put a space between -L/-I and the path that follows it.
The include directories to search is specified by -I flag, not -L.
Change:
LIBS_DIR = -I /home/b/flite-1.4-release/build/i386-linux-gnu/lib
INC_DIR = -L /home/b/flite-1.4-relase/include
to:
LIBS_DIR = -L /home/b/flite-1.4-release/build/i386-linux-gnu/lib
INC_DIR = -I /home/b/flite-1.4-relase/include
