i was wondering if there is away to avoid application from closing if a specific library not found? for example: if my application uses libPng and it wasn't found on the system running my app (binary and not source), is there anyway to just disable the part that uses png from my application?

View 2 Replies View RelatedI'm trying to learn how to cross-compile libraries (static and shared) and executables for the Blackfin + uClinux environment.At this point, I can successfully compile a stand-alone "Hello, world" but fail when trying to add a (static) library to the mix.Here's the source code I wrote:
Code:
#========== bar.h
void mytestfunc(void);
#========== bar.c
#include <stdio.h>

Googling for this returns talks about "name mangling", but I don't know if this is what it is, and how to change the source/command to solve it.
I have a bash script and I'm dropping a file on script launcher shortcut. Everything seems fine, only that after executing the script console window closes, so I can't see if some messages were produced during execution.
As I just recently switched from Windows, this kind of problem is solved there by adding 'pause' command in batch script, on which user has to press key and script will then continue (finish) or by launching through 'cmd /k' which makes console window persistent.
Googling I found about 'sleep' command and more appropriate for me 'read' command, so I did this:
Unfortunately, I can't see any effect of 'read' command as console windows again terminates after execution. Execution is successful BTW. So what's the catch?

View 2 Replies View RelatedI'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.
I've wondered for years how it works and how I can change it. For example, opening a document with vim, or opening a man page, and then exiting out of it will sometimes (depending on the distro) clear the screen and leave your prompt at the very top. other times, it leaves the contents of whatever you had open on-screen and your prompt is at the bottom.
View 1 Replies View RelatedI haven't been able to find it yet, but I may just be overlooking it in the programs I've tried. What I want, is to have a lossless music library on my desktop. Be able to browse this music library, select certain songs, and convert them to a mobile friendly format as I push them onto my phone for playback. Such as a flac to mp3/aac conversion while it pushes them onto the phone. Is there a program that does this? The last time I was able to do this, was in Windows using J River Studios Media Center, and it did this quite well.

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.

configure: error: readline library not found If you have readline already installed, see config.log for details on the failure. It is possible the compiler isn't looking in the proper directory. Use --without-readline to disable readline support. Now I tried to yum install readline-devel and the result was failure as below:

So I am thinking that maybe I have to tell configure where my readline libraries are. From the above, it looks like readline-6.0 is not on my computer, even though I went through the configure/build/install process for it.
