X Windows Programming Compilation Error
 

Hi i'm trying to compile a x windows program and I'm getting these errors, any hints off hand?

The hint is the first error line:
alpha_list.c:3:21: Xm/List.h: No such file or directory

You need to pass an option to your compiler for it to be able to find the X11 include files, should you have it already installed.
If you haven't, you first need to install the right package: looks like your program is using motif, so you need to install motif devlopment or equivalent (lesstif).

How do I include that path in this imake file?
 

How would I do that in this file??



SRCS1= alpha_list.c
OBJS1= alpha_list.o

SRCS2= list_callback.c
OBJS2= list_callback.o

SRCS3= scrolled_list.c
OBJS3= scrolled_list.o

SRCS4= search_list.c
OBJS4= search_list.o

SRCS5= simple_list.c
OBJS5= simple_list.o

PROGRAMS = alpha_list list_callback scrolled_list search_list simple_list

SYS_LIBRARIES = $(XLIB) $(XTOOLLIB)
LOCAL_LIBRARIES = -lXm

AllTarget($(PROGRAMS))

NormalProgramTarget(alpha_list,$(OBJS1),,$(LOCAL_LIBRARIES),)
NormalProgramTarget(list_callback,$(OBJS2),,$(LOCAL_LIBRARIES),)
NormalProgramTarget(scrolled_list,$(OBJS3),,$(LOCAL_LIBRARIES),)
NormalProgramTarget(search_list,$(OBJS4),,$(LOCAL_LIBRARIES),)
NormalProgramTarget(simple_list,$(OBJS5),,$(LOCAL_LIBRARIES),)



Thanks carmen

Have you motif libraries and include files installed on your machine ?

include files??
 

Yeah I installed lesstif . . . what do you mean include files?
Carmen

Libraries are binary files with a ".a" or ".so" extension.
Include files are having a ".h" extension and are included in C or C++ code with the "#include" preprocessor (compiler) directive.

You likely need to add something like "-L/usr/local/lib" to the Makefile compiler flags, see: http://www.lesstif.org/FAQ.html#QU5.0

Where do I put that??
 

Yes but where would I put that flag in my makefile??/

Carmen

Look for variables like CFLAGS having the "-lXm" string, and add the correct -L flag to the whole.
Unfortunately, you may face other issues later if the program you are trying to build was written a long time ago.

As jlliagre says, the linker must be able to find the libraries you're trying to use if linking is to be successful.
But you're having a compilation error and, as has been pointed out, posting a large mass of compilation errors
is not that meaningful. Instead, you should focus on the very first error: the header file that cannot be found.
Determine where that header is on your system and pass -I/path/to/header when *compiling* so the compiler
can find it. Compilation options are set in CFLAGS (or CXXFLAGS for c++ programs).
