General :: Build A Shared Library On System Using Same Command Used For Solaris?

Jun 22, 2011

I am able to build a shared library under solaris with
/usr/local/bin/g++ -G -o file1.o file2.o file3.o.
How do I build the shared library under linux using the same files?
I have tried to use the same command /usr/local/bin/g++ -g -o but I got some undefined references, even if those references are defined in one of the object files.

General :: Link Shared Library Against Other Shared Library?

May 27, 2010

I think that the solution is very simple, but I cannot reach this solution. I'm trying to build an that uses is compiled using C; is compiled using C++;

Inside "Aso.h" file I'had declared:


#ifdef __cplusplus
extern "C" {


There's no error to compile that, this library seems to be compiled correctly, but using the "nm" command the functions appear with "U" of undefined. Trying to build an executable using the library, I got this error: /lib/../lib/ undefined reference to `foo(int, int, int)' I think that to solve this problem it's only link the with the .o files generated at the compilation phase of my Bso. Using the "ldd" command I'm able to see that depends on, so what am I missing?

General :: Size Of The Library / Executable Is High In Compared To Solaris

May 18, 2011

We have a 32bit Gui application created using C++. We ported the application from Solaris to Linux. Issue we are facing is the size of the library and executable is very large in LINUX compared to Solaris. Red Hat Enterprise Linux 5.4 is the Linux version we using. Please find a sample dynamic library created. We would like to know the following behavior of LINUX is normal or not. Consider we created two files and Both having a single line of code.

Programming :: SDL Static Library - Shared Library ?

Apr 7, 2009

I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?

I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.

I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.

I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.

So... where is that part of SDL? All I can find are header files.

I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.

So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.

General :: Use Compile File Build Package Without Messing Up Library

Apr 11, 2010

I want to build a package from source using src2pkg, but I don't know how to avoid library miss match. Suppose I have Firefox 3.5.2 on Slackware 13.0 64 and I want to upgrade it to 3.6.2. Last time when I venturesomely installed Firefox-3.6.2-current into my Slackware 13.0, I got library miss match. Thus, instead of upgrading the whole packages to current (which is impractical and cumbersome), I want to build 3.6.2 from source. How can I do this? Is there any guideline how to use src2pkg? Or should I rather use makepkg? Do I need to create a Makefile?

Ubuntu :: Gcc Shared Library For G++ Application?

May 2, 2011

I built a shared library for some API functions (C files) and compiled them with gcc. Now I'm writing a c++ application (compiling with g++) and want to link my C API shared library and be able to use it from my application. Is this possible? At first instance, it's not quite working for me. I was able to link my shared lib just fine with a C application but got an "undefined reference to `apiFunction()'" error when attempting to do it with g++. Just want to see if anyone has any insight on this subject and make sure this mix is even is allowed.

Programming :: Can't Load Shared Library (but It's Right There!)?

Feb 15, 2011

I have visited these boards a few times, but never posted. Here's my problem: I was given the source to a program and asked to get it running on a 64-bit Debian 2.6.26 machine. Currently it is working on 2 64-bit OpenSUSE machines.

The application uses TCL TK for a GUI and everything compiles just fine; however, on startup, the user must enter one of three possible modules to load; when attempting to load these modules (tcl 'load' function), I receive this error:

Error in startup script: couldn't load file "../Build/": cannot open shared object file: No such file or directory
while executing
"load ../Build/ Mpf"

invoked from within

I know it's pointing to the correct files and gcc as any wrong paths are reported in make menuconfig.

Programming :: Put Header Files For A Shared Library?

Feb 26, 2010

I have written a simple library and ended up with a .so file. I have a header file from writing the code that describes how to use the functions in the source code I have written. I think this .h files needs to be available to other programs that access this code.

I have seen lots of tutorials on how to copy the .so file to the relevant directories and make links with the version number. What I can't find is where to put the header file so that any programs I write to use my new library can access the header.

Hope this makes sense. For example, I might use <stdio.h> normally, I will need to access <mylibrary.h> once is loaded (as far as I understand!)

It's weird, I've been using C compilers for embedded processors over ten years now and never given a second thought to how libraries and headers work behind the scenes!

Software :: Trying To Test C Shared Library Made In MATLAB

Jul 13, 2011

I am trying to test a shared library that I made in MATLAB. I'm not an expert, so if you need other info, or if i'm just not making sense I can try to clarify, or provide further info.First off:I'm using MATLAB 2011a, compiling c with the MATLAB compatible gcc-4.3, and all of this is running on 64 bit opensuse 11.3.

1) I've made a c shared library, header, and wrapper.
2) I've set the environment variable.
3) I'm having trouble creating an executable to test my .so with

I've also contacted MATLAB tech support, and they didn't help much. They said the wrapper (libatr2.c) is intended to be a template, and may not actually run my library unless eddited. Perhaps I should edit it to reference something called main? I'm not sure how to do that if that's the case.

But, mknod is only excutable by "root".

I don't want to let them know the root password.

I think that "sudo" and "fakeroot" are the way to use mknod...

Except for those command, are there any way to use "mknode" ?


Is there any solution for make "root file system ?"

Debian Programming :: Packaging Shared Library With Python Wrapper

Apr 12, 2014

I have written a shared library and successfully used debhelper 9 to create a Debian package from source using a Makefile generated by cmake. I then went about writing a python wrapper to that library and wish to package that wrapper in with the library so I can have a single distributable rather than 2 separate ones.

All of my attempts so far have me placing my python source and a file in the same directory as the makefile at the time where I call debuild.

From here I have tried a couple different configurations to my debian/rules file as seen below:

Attempt 1:
# -*- makefile -*-
dh $@ --with-python2 --buildsystem=python_distutils

This try seemed to package up the python stuff nicely but proceeded to ignore my makefile for the shared library and therefore ultimately failed.

Attempt 2:
# -*- makefile -*-
dh $@ --with-python2

This try ran make, but completely ignored the python stuff. From some research I have gathered that the --buildsystem flag tells debuild to ignore any makefiles in the directory, which obviously causes a problem in my case.

Another attempt was to modify the build dependency to first run make and then call the python build process that file looked like this

Attempt 3:
# -*- makefile -*-

dh $@
dh $@ --with-python2 --buildsystem=python_distutils
dh $@ --with-python2 --buildsystem=python_distutils

This appears to somewhat work as both processes do build, but a few of the python files are still not getting installed.

Is this the way I should be going about doing this? I've noticed that most python wrappers tend to package themselves individually and then make that package dependent on the library it is attempting to wrap.
