I am having Ubuntu 15.10 Desktop. I want to install libxml2. So any one tell me how i can install it. What i need to do to install libxml2 in my laptop. I am almost new to Linux, using it at least from 5-6 months.
Is there any Linux based compiler which supports graphics.h library?
I want to implement graphic programs, so please kindly let me know if there is any such software.
If not then how can I use it?
When I run a process that links to a shared library at runtime (linked when the process starts, not linked later with dlload()), where does it look for that shared library (.so) file other than LD_LIBRARY_PATH?
Background:
I have some C++ code that I wrote that uses a particular third-party library. I have installed the library and compiled my code on two different platforms, both Ubuntu but different versions, and different versions of gcc as well. The library was compiled and installed from source, and is located in /usr/local/lib on both platforms. When I compile my code, I link with the pkg-config --libs parameters for the third-party library and I've verified that pkg-config --libs returns the exact same thing on both platforms.
My code compiles successfully on both platforms, and LD_LIBRARY_PATH is not defined (or defined as empty: "") on both platforms. However, when I run it on one platoform it works fine, and on the other I get this error:
error while loading shared libraries: libthrift-0.9.0.so: cannot open shared object file: No such file or directory
Funnily enough, the ones that doesn't work is the newer version of Ubuntu and gcc. :/
So I'm trying to figure out how the working one is able to locate the library, so that I can make the broken one locate the library in the same way. (i.e., without setting LD_LIBRARY_PATH)
Update:
Here's my output from cat /etc/ld.so.conf.d/*
...on the working (older) system:
/usr/lib/mesa
/usr/lib32/mesa
/usr/lib/alsa-lib
# libc default configuration
/usr/local/lib
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
...on the broken (newer) system:
# libc default configuration
/usr/local/lib
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/mesa
Background: I'm trying to build my program but first I need to set up libraries in NetBeans. My project is using GLU and therefore I installed libglu-dev. I didn't note the location where the libraries were located and now I can't find them.
I've switched to Linux just a few days ago and so far I'm very content with it, however I couldn't google this one out and became frustrated. Is there way to find out where files of package were installed without running the installation again? I mean if I got library xxx and installed it some time ago, is there some-command xxx that will print this info?
I've already tried locate, find and whereis commands, but either I'm missing something or I just can't do it correctly. For libglu, locate returns:
/usr/share/bug/libglu1-mesa
/usr/share/bug/libglu1-mesa/control
/usr/share/bug/libglu1-mesa/script
/usr/share/doc/libglu1-mesa
/usr/share/doc/libglu1-mesa/changelog.Debian.gz
/usr/share/doc/libglu1-mesa/copyright
/usr/share/lintian/overrides/libglu1-mesa
/var/lib/dpkg/info/libglu1-mesa:i386.list
/var/lib/dpkg/info/libglu1-mesa:i386.md5sums
/var/lib/dpkg/info/libglu1-mesa:i386.postinst
/var/lib/dpkg/info/libglu1-mesa:i386.postrm
/var/lib/dpkg/info/libglu1-mesa:i386.shlibs
The other two commands fail to find anything. Now locate did its job, but I'm sure none of those paths is where the library actually resides (at least everything I was linking so far was in /usr/lib or /usr/local/lib).
libglu was introduced just as example. I'm looking for a general solution for this problem.
