Boost c++ library install - c++

I am not familiar with the usual build technique in linux I am using boost c++ library. Can any body guide me in installing and configuring boost c++ library. Thanks in advance

My environment is Linux Fedora 15. On it, one can easily install boost by typing,
$ yum install boost-devel
After installation, you'll find boost under /usr/include/boost/.
However, if you run,
$yum install boost
you'll only find .so of boost under /usr/lib/, like /usr/lib/libboost_timer.so.1.48.0.

It's OK if you're not familiar with the usual build technique because Boost doesn't use the usual build technique. Follow the instructions in the "getting started" documentation. Make sure you read all the way to the bottom of the page. The link to the Unix-specific instructions is at the very, very bottom.
For most parts of Boost, installation is synonymous with unpacking the tarball into your preferred include directory. Other parts of Boost require compilation, so go to the Boost installation directory, run ./bootstrap.sh, and then run ./bjam install.

depending on the Linux distribution you are using, you'll probably find boost is already built and packaged for you, e.g. on Fedora "yum install boost"

Rob Kennedy's answer is still valid except that is recommended now to install with ./b2 instead of ./bjam.

Can't find shared libraries in Boost (Linux Mint)

I just switched to using Linux Mint and I'm having trouble figuring out the way the default Boost package works on this system. Normally I'd just install a package called boost, and locate my way to the shared libraries, but on Linux Mint none of that seems to work.
I've done apt-get install libboost-all-dev, but I absolutely can't find any of Boost's .so files. Did I install the right package? If so, where are they? I'm especially in need of libboost_locale.so.
Thanks!
Usually, you can find them in /usr/lib (like here https://askubuntu.com/questions/263461/where-is-my-boost-lib-file). You can also try
apt-cache show libboost-all-dev

Does Linux command libboost-all-dev install and compile the header-only libraries?

On Ubuntu there is a command to install boost libraries which is something like this:
sudo apt-get install libboost-all-dev
does this command also install and compile the header-only libraries?
If not, what other terminal command would I need to execute so that I can install the FULL set of boost libraries?
My ultimate aim is to know which linux terminal commands I need to install (and have available) to obtain all of the boost libraries.
As is implied by "header only", one does not need to compile the header-only libraries. They're just headers.
Now, the libbost-all-dev package does install those libraries which need compilation (in addition to the header-only libs), but it does not compile them on the spot. Ubuntu is a so-called binary distribution, which means that it distributes packages in compiled form. Apt downloads the binaries and installs them immediately. This is in contrast to e.g. Gentoo which is a source distribution (and compiles everything on your machine).
In short, no further commands are necessary. Installing libbost-all-dev will install all available Boost libraries on Ubuntu.
Your questions, as posed, makes no sense.
The Debian / Ubuntu package libboost-all-dev has dependencies, and those dependencies do include the few binary library packages (eg Boost Thread, the formatting parts of Boost DateTime, etc pp). All those will get installed.
And yes, the intent of this meta package is to install the rest of the Boost development environment.
But it does not compile anything. All Debian / Ubuntu packages are pre-generated and built-offline and "just installed" at your end.
You can inspect the content of a package by browsing the online database.
But if you are only interested in header-only libraries I suggest to download the latest version of the boost libraries right from the official website; you should also learn how to build boost from the source because it's a know-how that you are very likely to use in a near future if you are relying on that library.
An equivalent step to browsing the online database, it's about using the following command
apt-cache show <package>
so, in your case
apt-cache show libboost-all-dev
and this will give you a very specific idea about what you are about to install.

Can't find bjam in boost homebrew installation

I installed Boost with homebrew(brew install boost) on my Mac running Lion with the purpose of extending python with an existing C++ program I have. Now I can't follow the starting guide because 1 - I don't have 'bjam' installed in my system and 2-I don't see the examples folder anywhere. My question is: how I am supposed to do the the c++-python linking with this homebrew installation without 'bjam'? is there some alternative method I should use or something I am missing here?
The right formula to install boost for linking c++ with python programs is:
brew install boost-build
as pointed out by senderle in the comments to my question. This installs bjam automatically.
For Windows, you go into $(BoostDir)\tools\build\v2\engine and run build.bat which automatically builds bjam (into the bin.ntx86 directory on windows). There is a build.sh file there too, but I've never used a Mac so I don't know if that will work for you. Otherwise, just do a Google search for a precompiled bjam executable for Mac OS X.
It should just be a case of downloading Boost then running "Bootstrap" followed by "Bjam".
Bootstrap should build you a Bjam executable in the Boost folder.

How do I install the boost library to my MinGW compiler?

I'm compiling from the command line using g++ on a Windows MinGW installation. How do I get boost...conceptually or if it is easy...what do I need to download and install?
I know this is an old question but for future reference for anybody coming to this page try this website,
http://nuwen.net/mingw.html
They have done all the hard work so you don't have to. The most recent distribution on this page has boost 1_52_0 (which is the latest version on the boost website as I'm writing this) including the separately compiled libraries (e.g. boost thread, boost regex etc) which I beleive you're asking for
I spent hours searching for a good solution for Boost 1.54. If you already have MinGW and you're just looking for instructions on compiling the binary boost libraries, try this:
From your boost_X_XX_X directory, go to
.\tools\build\src\engine
and type:
build.bat mingw
This will create a folder called bin.ntx86 or bin.ntx86_64 depending on your architecture. Add this directory to your PATH environment variable.
Return to your boost_X_XX_X directory and type:
bjam toolset=gcc
This worked for me on my system. I'd be interested to know if other systems have trouble with these instructions.
However there would have been a simpler, yet identical way; your steps until the bjam call are automatically done by bootstrap.bat:
C:\boost_1_52_0> bootstrap.bat mingw
Building Boost.Build engine
...
C:\boost_1_52_0> b2 toolset=gcc
Reference: https://stackoverflow.com/a/13257930/2171309
Thanx to Neal Kruis. This worked for me. I have Qt 5.4 with mingw 4.9 installed. I downloaded boost 1.59. Go to "...\boost_1_59_0\tools\build\src\engine\" folder
set PATH=%PATH%;c:\Qt\Qt5.4.0\Tools\mingw491_32\bin
build.bat mingw
go to "...\boost_1_59_0\" folder, change boost path accordingly
set PATH=%PATH%;c:\boost_1_59_0\tools\build\src\engine\bin.ntx86
bjam toolset=gcc

Enabling OpenGL in wxWidgets

I installed the wxWidgets source code, compiled it and am linking the libraries thus obtained with my application code. Now I need to use OpenGL in my wxWidgets application. How do I enable this?
For building on Windows with project files:
Assume $(WXWIDGETSROOT) is the root directory of your wxWidgets installation.
Open the file $(WXWIDGETSROOT)\include\wx\msw\setup.h
Search for the #define for wxUSE_GLCANVAS.
Change its value from 0 to 1.
Recompile the library.
For building on Linux and other ./configure based platforms:
Just use ./configure --with-opengl
(A mashup answer from two partial answers given by others)
If you're using configure to build wxWidgets you just need to add --with-opengl to your command line.
Just to add a little bit... If you're on linux you need to watch the logs when running configure. If it can't find opengl dev packages then it will turn opengl off with one line of warning which is easy to miss.
run it like this to make it more obvious what development libraries you're actually missing (it looks like the --with-opengl is on by default in 3.0.0 and possibly earlier versions of wxwidgets, but it can't hurt to include it I suspect).
./configure --with-opengl > configure.log
Once configure can find all the dev libs you think you're going to use you need to rebuild wxwidgets:
make
sudo make install
I had to install these on linux mint to make wxwidget's configure happy as far as opengl was concerned (and should also work for ubuntu) to get the dev libs I needed.
sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev
(Assume $(WX_WIDGETS_ROOT) is the root directory of your wxWidgets installation.)
Open the file $(WX_WIDGETS_ROOT)\include\wx\msw\setup.h
Search and find the option wxUSE_GLCANVAS. Change its value from 0 to 1.
Recompile the library.
