I want to build some package from source (e2fsprogs to be more concrete) and install its header files to my system. After that I will delete the build tree so it will not be accessible anymore. What is the right way to do this?
When I want to install program, I make simply:
$ ./configure
$ make
# make install
What are the equivalent actions when I want to install headers?
For e2fsprogs, quoting verbatim from the INSTALL file shipped with the sources:
7) Install the include files and libraries
You can run `make install-libs' to install the include files and
libraries. Please note that this installation is not needed for the
programs to work. It is only needed if you expect to develop other
programs using the libraries or if you want to compile other program
using these libraries (like the 4.4BSD dump and restore port).
More generally though, when I want to find out what is the 'proper' way to install something that has worked for others, I look at:
What the package looks like, in my favourite distro
How the package is built for my favourite distro

For some reason, my yum installer does not link library files. For example, I am trying to include in a c file, so I run sudo yum install c-ares. Everything installs, but when I run the program, I get the error:
fatal error: ares.h: No such file or directory
The same thing happens when I try to include other packages, such as
Any thoughts on how I can get yum to put these libraries in the right place?
There are usually two packages - one containing the library so you can run existing programs and another for development that contains the headers that has the name with "-devel" appended to it.
So in this case you need to also install "c-ares-devel"
you need to install the development packages. Like c-ares-devel
I have to create SOAP services in C using axis2C. But since axis2C is kind of not maintained properly as per this question, I have to use axis2C unofficial source code. But I could not see configure file to build the sources. How should I build this. I checked all the documentation both in here and in the github repo but no luck. All points to the axis2C official documentation. Should I copy the sources from unofficial to official code and try with the configure script in official folder ?
This project probably uses the GNU build system. In this system, ./configure is a portable shell script that is automatically generated from hand-written input files, the main file is configure.ac.
So, distribution packages of the source will contain ./configure, therefore enabling anyone on any platform with a sh-compatible shell and a make utility to build the software. But as it is a generated file, you will not find it in source-code repositories, e.g. on github.
To build a package using the GNU build system directly from source controls, you have to use the GNU autotools yourself to generate ./configure. In order to do this, install the following packages:
autoconf -- generates ./configure from ./configure.ac.
automake -- generates portable makefile templates Makefile.in from Makefile.am (those templates are then filled with values by the ./configure script to write the final Makefiles)
libtool -- tools for building dynamic shared objects on different platforms
Then, the command autoreconf -i given in the root of your source package should generate the ./configure script for you.
Note that there are packages providing a script ./autogen.sh (or similarly named). If this is there, you should call it instead of running autoreconf -i yourself, it might contain additional necessary preparation steps. ./autogen.sh will typically directly run the generated ./configure for you.
I am working on a school project in a limited environment (archlinux) where I don't have root access. The subject says that I am allowed to use all libraries that are already installed. I am coding in C using gcc.
How to get a list of all those libraries ?
For those libraries managed by the pkg-config utility, the following command will show all installed libraries:
pkg-config --list-all | less
However, not all libraries are so managed so you may be forced to go through the /usr/lib and /usr/local/lib directories.
As noted, not all libraries necessarily use pkg-config. Given that this is ArchLinux, as a fallback you could learn to use the package manager, to list the installed packages. That is called pacman.
Anything that is installed as such on ArchLinux would be part of a package.
The query options can show you all of the files installed for given packages:
To list all files for a given package, use pacman -Qlpackage_name
To list all packages, use pacman -Q
(scripting that, to list all ".so" files which are installed, by package name would be an interesting exercise).
ls /lib /usr/lib /usr/local/lib
I use Tcl_CreateObjCommand to build a Tcl extension in C called libA.so, the C code call the function from an external C library called libext.so, where should I put libext.so, so that the tcl could find and load it when it load libA.so
Use a package installer
If you have a package manager you should install tcl/tk with it.
sudo apt-get install tk
or you might want also tk-dev (which is sometimes called tk-devel):
sudo apt-get install tk tk-dev
Install manually
You can put so's manually in /usr/local (libraraies in /usr/local/lib/ and include files in /usr/local/include/), But remember to avoid installing them under /usr if you do have a packaging system.
There's also an option of putting them under your project directory, but you'll have to help the dynamic linker find them (using LD_LIBRARY_PATH or ld.so.conf). Also, you'll have to update your project's include paths and library paths.
I am a begineer trying to get code in C. I am working on a Mac and using xcode. My only past experience has been with java using eclipse and everything was pretty straight forward. I have almost no experience with terminal.
I am required to learn a bit of C for a project I will be working on and the learning of syntax is coming along okay, but I am at a point where I need to include some libraries in my c program. Specifically I am attempting to make plots with gnuplots.
I have downloaded gnuplot-4.6.3 from their repository and I do not even know how to install the files. I have been looking around and have tried using terminal to use the ./configure command when I am in the gnuplot-4.6.3 directory. But I really don't know what I am doing so I don't even know where to go next or what to do next.
Sorry if this is so trivial, I honestly just have never done this before and I cannot find a good tutorial on what to do.
Thanks for any help you can offer.
I would recommend using MacPorts for installing third-party tools and libraries. It knows the dependencies required and will install them as part of the installation.
Download it from macports.org.
Install it, and allow it to modify your ~/.profile so that /opt/local/bin is in your $PATH (any issue then just do export PATH=/opt/local/bin:$PATH from the command line).
sudo port selfupdate
sudo port install gnuplot
Now that will install the library into /opt/local/lib with the include files in /opt/local/include, so now just add that library to your Xcode project. Select the target and in the Build Phases tab open up the Link Binary With Libraries and press the + button and select Add Other. Now find /opt/local/lib/libgnuplot.a (I am assuming that's what it's called; I don't have it installed my self):
Now add /opt/local/include to your Header Search Paths so the compiler can find the gnuplot header files. Select the target and in Build Setting type in "header search" in the search box. Now double-click on the Header Search Path in the target column (or the project column to the right) and add /opt/local/include:
It's fine! You're learning then! Keep up! When I hit this kind of problem you may want to learn about the basis for linux gcc/g++ compilation and linking processes. Then you should learn Cmake and Automake, which are basically packages to configure projects before compiling building.
A typical (good) project in Unix systems build with commands
./configure
make
sudo make install
or
cmake CMakelists.txt
make all
sudo make install
That's what you need to do after downloading a source tarball online to install unix programs.
Now since you are using Mac, there are so-called package installers, one which is macports and homebrew. I personally suggest homebrew than macports here (I've tried both, although macports still outnumber homebrew with the number of repos, homebrew has the newest support, especially when upgrading to a new OS). So to install homebrew you can do
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Execute that in your terminal (see http://brew.sh/) for more information.
Then you could simply install GNUplot by
brew install gnuplot
