Hi,



I tried to compile a C source code, using make command:



The Makefile script is:



BINDIR = ./

LIBDIR = /foo/im/lib/Linux24

INCLUDE = /foo/im/include



CC = gcc

CFLAGS = -g -I$(INCLUDE)

LIBS = $(LIBDIR)/libim.a $(LIBDIR)/libim.so \
-lm -L/usr/X11R6/lib -lX11

You are linking against libim twice, once static and once dynamic, what you
may mean is

LIBS = -L$(LIBDIR) -lim -lm -L/usr/X11R6/lib -lX11

OBJS = rotation.c

BIN = rotation



$(BIN): $(OBJS)

$(CC) $(CFLAGS) -o $(BIN) $(OBJS) $(LIBS)


Not really an answer, but this is wrong too, you should have something like
this instead:

OBJS = rotation.o

BIN = rotation

$(BIN): $(OBJS)
$(CC) -o $@ $^ $(LIBS)

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

but with only one source file it doesn't really matter



install: $(BIN)

mv $(BIN) $(BINDIR)



clean:

rm -f $(BIN) *.o *~







but then I got this error message when I run make



iuri@server1:~/mat056/AULA28.03.07$ make

gcc -g -I../im2_6_linux24/im/include/ -o quantizacao quantizacao.c

sr/X11R6/lib -lX11

quantizacao.c:1:16: error: im.h: No such file or directory

quantizacao.c: In function 'main':

quantizacao.c:12: warning: incompatible implicit declaration of built-in
function 'malloc'

Seems like you are not including stdlib.h so malloc is not defined

quantizacao.c:22: error: 'IM_TIF' undeclared (first use in this function)

quantizacao.c:22: error: (Each undeclared identifier is reported only
once

quantizacao.c:22: error: for each function it appears in.)

make: *** [quantizacao] Error 1

Strange! What is this quantizacao file ? It doesn't appear in the makefile.

I can see it’s missing the im.h of my gcc lib. Does anyone know how to
solve this problem? Even apt-get any lib that has im.h?

what is im.h supposed to be a part of? If you don't know, than where did
you get the code and what's its intent?

Good question ;) Maybe are you looking for libimlib ? (an image manipulation
lib, replacement for libxpm)


There is no debian package that contains im.h or libim.a or libim.so
Only reference I found is national language support for AIX which is a
proprietary UNIX by IBM
