According to this question, I need to install macports to get libtool and various other dependencies.
Is it possible to do this without macports? Can I download these files individually somewhere?
Installing macports for autotools is not required, since you can build them from source. It's probably not as convenient, but it works. The autoconf, automake, and libtool are available from ftp.gnu.org.

I cloned this repo and then...
cd build_unix
../dist/configure
make
sudo make install
Then I go to the project I am trying to compile and run stack install I get the following...
Configuring BerkeleyDB-0.8.7...
Cabal-simple_mPHDZzAJ_1.24.2.0_ghc-8.0.2: Missing dependency on a foreign
library:
* Missing C library: db
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
This is on OSX
Rather than compiling from source, you could use homebrew:
brew install berkeley-db
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
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:

I'd like to try to make a user-space device driver using libusb on Mac, but I'm confused where to start. In the SDK installer (which I got from http://www.ellert.se/twain-sane) it said something about examples which I couldn't find anywhere on my computer.
Could anyone please describe how do I set up libusb for development on OS X? May I use Xcode? What should I include in my code?
brew install libusb-compat
Working on OSX Yosemite 10.10
Easiest way to do this:
brew install libusb
Homebrew is amazing and I recommend it for all developers that use Mac.
I tried to install the SDK from the aforementioned website and couldn't find a trace of it once the installer finished. Though I did find some libusb items at /usr/local/Developer/SDKs/MacOSX10.6.sdk/usr/local/ I'm not sure it came from that installer as I couldn't find any examples, just libraries and they were labeled as libusb0.1.4.
On the other hand, since you asked your question with the macports tag, I'd suggest you use that to install libusb as it at least puts everything in a known location:
/opt/local/var/macports/software for install files
/opt/local/lib for libraries
/opt/local/include for header files
If you've never used macports then once you have macports installed then you can install libusb using
sudo port install libusb
to install libusb1.0 or
sudo port install libusb-legacy
to install libusb0.1.12.
Then you can create a project in Xcode and link to the libusb-*.a library contained in /opt/local/lib (in my directory my library file is called libusb-1.0.a since I have libusb1.0 installed).
I don't have much experience using Xcode so I can't help you any further down this path. Personally what I've done so far is use a Python wrapper called pyusb to do some quick experimentation with libusb as I don't have to do IDE setup or library/include file setup with Python.
UPDATE: Poking around the macports install directory for libusb, I didn't find any examples included which was a bummer. If you've gotten this far then I'd suggest going directly to the source for libusb, download and unpack the tar file, and building the code that's in the example directory. Sorry for the roundabout way of getting libusb examples but I've really come to appreciate the organization macports imposes on installations which saves me quite a bit of future pain (like when I want to uninstall).
once libusb is installed using following command:
brew install libusb
or
brew install libusb-compat
link libusb to the build system using
brew link libusb
to be able to configure any project depending on libusb, use pkg-config:
pkg-config --cflags libusb-1.0
and
pkg-config --libs libusb-1.0
before calling any ./configure
I want to install gettext but i cannot because my AIX says that gettext is dependent on glib and when i try to install glib it says that I cannot because glib is in turn dependent on gettext.
Please let me know how I could get past this situation?
root [rover]% rpm -i gettext-0.17-1.aix5.1.ppc.rpm
error: failed dependencies: libglib-2.0.a(libglib-2.0.so.0) is needed by gettext-0.17-1
libxlsmp.a(smprt.o) is needed by gettext-0.17-1
root [rover]% rpm -i glib2-2.22.5-2.aix5.1.ppc.rpm
error: failed dependencies: gettext is needed by glib2-2.22.5-2
You really have 2 problems:
error: failed dependencies: libglib-2.0.a(libglib-2.0.so.0) is needed by gettext-0.17-1
libxlsmp.a(smprt.o) is needed by gettext-0.17-1
The first error is indeed solved by what is said above (DO NOT use the --nodeps option in this case, it can cause really bad things to happen): use rpm -i (or -U for upgrade) to install both gettext and glib2 at the same time. If you have both in the same directory you can just use rpm -ihv (or -Uhv) *.rpm to install all of the RPM's at once, and it will resolve interdependencies that way.
HOWEVER, you still will not likely be able to install gettext due to #2: libxlsmp.a is a SECOND library/dependency that you need to solve.
It's my understanding that this library comes from a base AIX package (NOT an RPM/Open Source package) that will need to be installed from your AIX installation Media by installp. According to other web research it's the "xlsmp" package.
You have to pass in both files at once for dependency resolution to work: rpm -U gettext.rpm glib2.rpm.
I am not sure this will work or not, but install one of the package ignoring the dependencies.
use --nodeps flag of rpm to do this. Once it is installed, then go ahead with the other package.
root [rover]% rpm --nodeps -i gettext-0.17-1.aix5.1.ppc.rpm
Make sure to resolve other dependencies (if any) later if you are following this.
