Compile static library [Archive]

View Full Version : Compile static library

series

November 21st, 2005, 09:59 PM

I have created a static library. Imaginative as I am, I call it "library.a". It is an archive containing all the object files of my library, which is actually just one file: library.o

Now I'm not sure how to link this library into my program, and I'm not sure of how to configure where g++ searches for libs. I really don't want to install my library on the filesystem, I want to link it into my program from the current dir.

The relevant files are: "main.cpp", "library.a", "library.o", "library.h", "library.cpp".

How do I compile main.cpp so that it can use the functions in library?

g++ -c main.cpp
g++ main.o library.a -o main

should do the trick.

i had compiled and runned the gnash version 7, now i had all .so files,
from all .o i build .a files ,now how can i link this libraries so tht i can run gnash can u help me.

i had the files libgnashgui.a ,all gnash files .o into . a i made, can u help how to link and run gnash using this static same idea as u impemented can u suggest me some idea

thanks

Alright. That was just too easy :cool:

It first didn't work for me because I reversed the order to g++: first library and then main (which seemed more logical for some reason). Then I was unsure if g++ could even handle the archive by itself... well, thanks, it works fine now.

The ordering of the library(-ies) is important. When the linker is processing the object files and detects an unresolved function, it tries later to find it in a library. If it can't, then the build will fail due to undefined references.

There are cases when one library (e.g. libB) is dependent upon a another (e.g. libA). Thus, when linking, libA would have to be specified before libB. At least that's how I remember it to be. 'gcc' has evolved a lot in the last couple of years so maybe that's not true anymore. But I do recall issues with circular dependencies (a strong clue that a bad design has been implemented).

By the way, you may want to rename your library to a more conventional form. Generally the name of the library begins with the prefix "lib". Thus an example would be libfoo.a (or libfoo.so).

When compiling/linking, the statement could look like:

$ g++ myFile.cpp -L../libs -lfoo

The -L option indicates a path to search for user-defined or 3rd-party libraries, and the -l is used to define which library to reference (read). The usage of "foo" above is the correct syntax. The linker knows to prefix that name with "lib", and it will deduce whether it is a dot-a or dot-so file (within ../libs).

Please see the comments I posted to 'series'. Let me know if you still require assistance.

can u tell me exact command how to link this .a libraries and run gnash

The best thing to do is create a Makefile, one for the library and another for the application.

Here's an example of one for the library:

#
# File: Makefile (for library)
#
CC=gcc
LIB=libGnash.a
LIBDEST=./

LIBSRC=abc.c def.c

LIBOBJ=$(LIBSRC:.c=.o)

install: $(LIB)
<tab>@echo lib Makefile - installing $(LIB)
<tab>@install -m 444 $(LIB) $(LIBDEST)

$(LIB): $(LIBOBJ)
<tab>@echo lib Makefile - archiving $(LIB)
<tab>@$(AR) r $(LIB) $(LIBOBJ)

.c.o:
<tab>@echo lib Makefile - compiling $<
<tab>@$(CC) $(CFLAGS) -c $< -o $@

Then for the application:

#
# File: Makefile for application
#
CC=gcc
LIBDIR=../lib
LIBS=-lGnash

SRC=app_abc.c app_def.c

OBJS=$(SRC:.c=.o)

EXE=myapp

all: $(EXE)

$(EXE): $(OBJS)
<tab>@echo application Makefile - linking $<
<tab>@$(CC) $^ $(LIBDIR) $(LIBS) -o $@

.c.o:
<tab>@echo application Makefile - compiling $<
<tab>@$(CC) $(CFLAGS) -c $< -o $@

Wherever you see <tab>, replace that with a tab-character. Of course, modify the names of the source files, where you want your library installed, etc.

You can also consider adding other things to the Makefile, but for now I think what I have given will get you going.

Btw, if you are developing a C++ application, modify CC to be g++, and in lieu of CFLAGS use CXXFLAGS.

Please let me know if you still have questions.

P.S. Edited for readability.

can u tell me exact command how to link this .a libraries and run gnash

If you want to type the command in the command-line to link, then here's an example:

gcc file1.c file2.c -L./ -lGnash -o myapp

The file1.c and file2.c are the application modules.

The -L is used to specify the path where libGnash.a resides.

The -l is used to specify the library that will be linked with the application files. Note that the 'lib' and the file extension of the library are not required in the name.

The -o is to direct the linker to create the executable with the name provided. Without the -o, the resulting executable would be called a.out.

actually i had all .a files now i have to link this files so tht gnash can run,

using this command

arm_v5t_le-ar rc libgnashbackend.a .libs/render_handler_tri.o .libs/render_handler_agg.o

i created all .a file example libgnashgui.a,libgnashserver.a
like this i had all .a files so how can i link this files so tht gnash can run

can u help me out
urgent

this all .a is a x-archive which contain .o files

I am not sure what you are trying to do. Your previous post includes the command (in an awful font mind you) the command you issued to create an archive of object files.

Btw, the usage of the 'c' option is not required. Thus this would suffice:

$ arm_v5t_le-ar r libgnashbackend.a <list of object files...>

To link an application that uses this archive library, issue a command similar to the following:

$ arm_v5t_le-g++ <list of .cpp files...> -lgnashbackend <-lotherLibraries...> -o appName

Then run your application as such:

$ ./appName

If you have other libraries to build with your application, specify them using the "-l" option, and ensure that they are specified in the correct order. In other words, if library A is dependent on library B, then specify B before A.

Like I said earlier, when linking so many libraries, one can expect a nightmarish situation like you have posted... thousands of link errors.

All I can suggest is that you try to tackle one at a time, or at least the easy ones.

I noticed that you are specifying libgnashgui.a twice. There is also a complaint about "main" being referenced (declared) twice. Find out where main() is defined (actually in which library it is defined), and remove the second occurrence from your list.

Also, if you are using Makefiles, try to eliminate the full path indicating where the libraries are located. In other words, you should not see something like /home/saritha/arm/LibSourceForGnash in the paths above. Redefine the paths so that they are relative to the location of the Makefile linking the libraries.

Also check your Makefile for where the following statement resides. It appears that a -L (and a white space) is missing between sslinstall and the next path; or perhaps a mistake when you copied/pasted the statement?

-L/home/saritha/arm/LibSourceForGnash/ssl/sslinstal l/home/saritha/arm/LibSourceForGnash/ssl/sslinstal l/lib

P.S. In the future, when you post output, select it and mark it up as PHP.
