Locating Boost Libraries in Ubuntu - c++

I want to build an autotools project which is making use of the boost libraries program_options and iostreams. Therefor I install those libraries:
sudo aptitude install libboost-iostreams-dev libboost-program_options-dev
Now ./configure is fine and the progam compiles. However the linking fails:
/usr/bin/ld: cannot find -lboost_program_options-mt
/usr/bin/ld: cannot find -lboost_iostreams-mt
This is a well documented issue and can be fixed either by fixing the autotools stuff or by linking boost_program_options to boost_program_options-mt and so forth. I choose to do the latter since this is not my project. However I am failing to locate the libraries installed in Ubuntu:
locate *boost*
returns a list of documentation and package information and some boost libraries I am not looking for. locate *program_options* is empty. The library is not under /usr/lib or /lib ... Any ideas?

For me they are under /usr/lib64 in ubuntu 13.04. But I would use boost m4
to let autotool take care of these dependencies automatically. So by including boost m4 in your configure.in, you can specify which boost modules and versions you require. Morever it would also find the required paths for you.

sometimes its impossible, especially for smaller apps and custom projects,
for future, boost includes are in /usr/include/boost ,
of course it depends on system type and distribution

linking boost filesystem and boost iostream libraries in ubuntu 14.04

I downloaded boost 1.61 and extracted it at /usr/local/boost_1_61_0 and while installing i set the prefix path to /usr/local/ where all the boost libraries are installed. I am trying to install FRESCO tool for DNA data compression which is built using Boost c++ libraries (Downloaded from https://github.com/hubsw/FRESCO). They have given make utility to install FRESCO tool.
But when I try to run make, I get errors regarding BOOST:FILESYSTEM and BOOST:IOSTREAM libraries as follows
undefined reference to `boost::iostreams::detail::gzip_header::reset()'
undefined reference to boost::iostreams::detail::zlib_base::~zlib_base()'
undefined reference to `boost::filesystem::detail::create_directories(boost::filesystem::path const&, boost::system::error_code*)'
and many more related to boost iostream and filesystem.
In FRESCO they mentioned they require BOOST 1.51(later), boost filesystem,boost iostream, boost threading-mt.
Can someone please suggest me where I am going wrong? How to link the boost filesystem/iostream if i am using make utility of ubuntu to install FRESCO tool?
I'm trying to compile boost as dependency for my project and I get similar errors.
I see two issues for your case:
I don't use FRESCO, but from its makefile I see -lboost_system -lboost_filesystem -lboost_iostreams, so it expects a global Boost installation. You don't need to compile Boost for that, you can use the packaged versions of your system. In ubuntu they can be installed with sudo apt-get install libboost-dev libboost-filesystem-dev libboost-iostreams-dev.
If you really want to compile Boost, that error message is about a part of boost that needs extra configuration for compiling it (compression filters). It tries to link to an object with some definitions that are not compiled by default (It would probably link correctly if FRESCO didn't use compression filters). Assuming that you are compiling with Boost.Build, for Boost.Iostreams this issue is explained (not very well IMO) in https://www.boost.org/doc/libs/1_61_0/libs/iostreams/doc/installation.html :
To build with Boost.Build, run bjam from the directory libs/iostreams/build, or from the Boost root directory. If you want to use the compression filters, you may need to set several Boost.Build variables indicating where the source files or pre-built binaries are located.
EDIT
There are other alternatives to compile Boost.Iostreams:
If you have installed bzip and zlib in the system, Boost.Build autoconfigures the compilation of those compression filters. In ubuntu, do sudo apt-get install libbz2-dev zlib1g-dev (in xenial, I haven't checked if the names are different in other versions).
If you can't install zlib and libbgzip in the system, and you compiled them yourself, put this in a file tools/build/src/user-config.jam inside the downloaded folder of boost:
using zlib : 1.2.11 : <include>/path-to-your-compilation/zlib-1.2.11 <search>/path-to-your-compilation/zlib-1.2.11 ;
using bzip2 : 1.0.6 : <include>/path-to-your-compilation/bzip2-1.0.6 <search>/path-to-your-compilation/bzip2-1.0.6 ;
Just replace path-to-your-compilation.
Then, do ./bootstrap.sh --with-libraries=filesystem,iostreams and ./b2.
Documentation for this (notice I'm using Boost 1.65):
user-config.jam: https://www.boost.org/doc/libs/1_65_1/doc/html/bbv2/reference.html#bbv2.reference.tools.libraries.zlib
general Boost install: https://www.boost.org/doc/libs/1_65_1/more/getting_started/unix-variants.html#prepare-to-use-a-boost-library-binary

Some doubts about libraries

Say, I want to write a program in C++ in Linux and I need some specific libraries. There are 2 ways of getting these libraries:
Using the command line--> apt-get install library
Downloading and extracting a .zip or .tar file from their website.
Now my questions are:
For the first method I have seen libraries being downloaded with apt-get install library and apt-get install library-dev. I know dev means development or developer, but what is the difference between installing the dev and not installing the dev? What does dev do, exactly?
For the second method, do I need to build the libraries using a compiler? Because I have seen tutorials doing it but the OS used was usually Windows, do I only have to build them on Windows and not Linux?
Also, say I can only use the 2nd method for a certain library and not the first one. After extracting, what am I supposed to do? Is there any default way of installing a library manually or is each library different?
Finally, when I use the first method where is the library installed to? Is it /usr/local/lib, /usr/lib or /usr/include? Because when I have to link to these libraries in the Linker's settings I only write their name, not the path so I assume there is already a default path for libraries to be in.
One last question: Is there any default way of installing and using libraries in general or does that depend on what I want to do, programming language, etc...?
The second method is very broad because it depends entirely on the how the project is designed including the build system used etc. Things get a little more conformant when you use a distribution's managed packages.
If you want to develop a program that uses the library you need the library-dev package that usually contains the C/C++/etc.. header files.
Many development package conform to a standard tool that helps your build system find the libraries header and binary files.
For example libcurl uses the pkg-config system so its compiler components can be found from the command line like this:
pkg-config libcurl --libs # print the library link flags
You can then add that to your Makefile (or whatever build system you use):
program:
g++ -o program program.cpp $(shell pkg-config libcurl --libs)
The $(shell pkg-config libcurl --libs) part adds the correct compiler flags to link with the library.
Not all dev packaged use pkg-config. Some come with their own tools (like mysql_config) while others let you guess and try to figure it all out for yourself (looking at you libclang).

Installation of ndnSIM 2.0 (Name Data Networking)

I am trying to install ndnSIM 2.0 Link on Ubuntu 12.04. I have followed all the instructions mentioned Link 2.
When I run ./waf configure while in ndn-cxx folder I get the following error
Checking if CryptoPP library works: yes
Checking boost includes: 1.57.0
Checking boost libs: lib system not found in /usr/lib
The configuration failed
(complete log in /home/rani/Desktop/ndnSIM/ndn-cxx/build/config.log)
Do I need to install some more libraries or there is some link problem as
Boost Library(1.57) is installed in /usr/local/lib? I have even followed the FAQ!
So ./waf cannot find the boost libs. Please check where the boost libs have been installed, most probably they are in /usr/local/lib in which case simply issue:
./waf configure --boost-libs=/usr/local/lib (instead of just ./waf configure).
You can ask any questions at their mailing list.
first of all, the error you got refers to ndn-cxx, which is our library, not ndnSIM itself.
This error indicates that your installed boost libraries could not be found by ndn-cxx.
Please make sure that you installed the boost libraries correctly and then search for the directory, where they were installed.
Typically, the boost libraries are installed under the /usr/lib directory. If your boost libraries have been installed somewhere else, you may use the following option to indicate the specific directory and configure ndn-cxx:
./waf configure --boost-libs=

Installing Poco on Mac

I am trying to install Poco on Mac. I downloaded the basic edition from here. As per the instructions, I did configure, then did make. It took a long time, but it succeeded (my make version is 3.81).
After this, when I did sudo make install, it finished pretty quickly. But as per the documentation, which states that I should have the libraries installed in /usr/local, I don't see them. The /user/local/include/Poco has all necessary header files, and /user/local/lib has lot of dynamic libraries like libPocoFoundationd.30.dylib, etc, but I don't see the libraries which I need to use.
How do I get them? My system is OS X 10.10, Yosemite.
If you have the entries like libPoco*.30.dylib (dynamic library binary) and libPoco*.dylib (link to the library), that's it. If you are looking for the static libraries, they are not built by default. To build static libraries, do
configure --static
and, after make install, in /usr/local/lib you will find libPoco*.a etc.

how to get libtorrent to see boost?

I am compiling libtorrent-rasterbar-0.16.16 with msys and mingw.
./configure runs fine, until it gets to the boost library check.
I have boost 1.51, and I set $BOOST_ROOT, but that did not work.
Checking for boost libraries:
checking for boostlib >= 1.36... expr: syntax error
configure: We could not detect the boost libraries (version 1.36 or higher). If
you have a staged boost library (still not installed) please specify $BOOST_ROOT
in your environment and do not give a PATH to --with-boost option. If you are
sure you have boost installed, then check your version number looking in <boost/
version.hpp>. See http://randspringer.de/boost for more documentation.
checking whether the Boost::System library is available... no
configure: error: Boost.System library not found. Try using --with-boost-system=
lib
I tried the --with-boost-system= option, and that did not work either. I also copied libboost_system-mgw47-mt-1_51.a to the same directory as libtorrent... but it did not work.
What am I missing?
I have boost 1.51, and I set $BOOST_ROOT, but that did not work
It is very likely that configure can’t find boost header files. What you need is both the library and the sources, and your best avenue is still setting BOOST_ROOT.
On a linux box you would be installing the boost-devel package, but for mingw you should download the boost sources directly and unpack them. Then please make sure you are running,
BOOST_ROOT=/path/to/boost_1_51 ./configure
