I tried to build boost in a separate path on my Ubuntu 18 Linux system. I cloned the GIT repository since I want to have the latest version available (the package repositories provide an old version only). The library I want to use is boost::timer.
This is what I did:
git clone --recursive https://github.com/boostorg/boost.git
cd boost
./bootstrap.sh
./b2 headers
./b2
This kind of worked. However I expected the static library to be located in a different path. It was compiled into this path:
.../boost/bin.v2/libs/timer/build/gcc-9/release/link-static/threading-multi/visibility-hidden/libboost_timer.a
This path is very verbos and it contains the compiler and its version which means I would need to update the paths when updating GCC or changing the compiler.
I would have expected it here:
.../boost/libs/timer/libboost_timer.a
Did I do something wrong? Is the placement expected that way?
Ok, when reading the build output carefully even a fool like me could notice that the actual path is boost/stage/lib. All built libs can be found there.

I am trying to build a program on MacOS and that program requires Eigen version <= 3.3.7 but mine has 3.3.8 with brew install eigen
I went to Eigen website but 3.3.7 source is no longer available anymore.
Any workaround?
Thanks a lot!
Updates: thanks a lot but I am still very confused with how to proceed. Below is the information of the installation details and directory info.
The directory of the program source code that I want to build look like:
program
cmake
Cmakelist.txt
build
the program has the following instructions:
Create the build directory in the source tree root
mkdir build
Configure cmake, from the build directory, passing the Shogun source root as an argument. It is recommended to use any of CMake GUIs (e.g. replace cmake .. with ccmake ..), in particular, if you feel unsure about possible parameters and configurations. Note that all cmake options read as -DOPTION=VALUE.
cd build
cmake [options] ..
Compile
make
Install (prepend sudo if installing system-wide), and you are done.
make install
Sometimes you might need to clean up your build (e.g. in case of some major changes). First, try
make clean
Then I have downloaded eigen3.3.7, where the INSTALL file is as following. How should I proceed?
Method 1. Installing without using CMake
****************************************
You can use right away the headers in the Eigen/ subdirectory. In order
to install, just copy this Eigen/ subdirectory to your favorite location.
If you also want the unsupported features, copy the unsupported/
subdirectory too.
Method 2. Installing using CMake
********************************
Let's call this directory 'source_dir' (where this INSTALL file is).
Before starting, create another directory which we will call 'build_dir'.
Do:
cd build_dir
cmake source_dir
make install
You can install Eigen 3.3.7 by compiling the source code(available here).
I have been trying to build boost Version 1.73 from its git repo https://github.com/boostorg/boost.git on Windows. And am able to build it, however when I try to use it in code, it is looking for boost 1.74 instead of 1.73.
Here are the steps I took to build it:
git clone --recursive https://github.com/boostorg/boost.git
cd boost
rm -rvf more
git checkout tags/boost-1.73.0
git submodule update --init --recursive
Once the cloning is done. I do the following:
bootstrap.bat
.\b2 --toolset=msvc-14.2 variant=release,debug threading=multi link=shared,static runtime-link=shared,static address-model=64,32 architecture=x86 --layout=versioned --stagedir=out\\release -j %NUMBER_OF_PROCESSORS% -q --hash
Boost gets built as expected, however when I use it in my code to be linked statically. The linker looks for boost version 1.74, which is the latest on master as of now. However if I download the sources from here and then build it, everthing works as expected.
Can anyone help me in pointing what I may be doing wrong?
TIA
You wrote:

You can verify that the string 1.74 doesn't occur in the Boost source code at all, using git grep 1\\.74 (two backslashes are needed with a POSIX shell, perhaps only one needed with a Windows command line?). I did this, and 1.74 really isn't there in the source code except in one file doc/test/test.svg as part of a number unrelated to versioning.*
In addition to the Boost which you are building, it seems that there is, or was, another version of Boost on your system, and MSVC is trying to use that. In your project that tries to use Boost, you need to look closely at the project properties. Look at the paths that MSVC searches for libraries and headers, there must be something there which isn't using the Boost that you build.
It's not clear why you don't also see this problem when you download the source from dl.bintray.com - that source is not identical to what you get from github, but the differences appear to be insignificant.
*Sadly, it seems that git grep is not as reliable as I would have thought. Using grep --recursive 1\\.74 * finds many other instances of 1.74. However, I believe they are all in numerical constants unrelated to versioning.
Boost using this build system I'm not otherwise familiar with, based on "Jam" files. Now, I've forked and cloned a specific Boost library (program_options), and I want to build it and perhaps also run the tests. I notice a build/Jamfile.v2 - what should I do with it?
I tried apt-get install jam on my distribution, but that did not get me very far:
$ jam -fbuild/Jamfile.v2
warning: unknown rule project
warning: unknown rule boost-lib
don't know how to make all
...found 2 target(s)...
...can't find 1 target(s)...
Also, do I have to get the absolute latest development version of all of Boost to build the cloned library against, or can I use a local boost release I already have?
Notes:
I'm on a recent GNU/Linux distribution (Mint 18.3 but this shouldn't matter).
What I've done, based on #SergeyA and others' advice, is:
Clone all of Boost, recursively (see this page (this will create a boost/ folder )
cd boost
in .git/modules/my_boost_lib/config, change the origin URL to your fork
in .gitmodules, under [submodule "my_boost_lib"], change the URL to your fork
execute git submodule update --init libs/my_boost_lib/ (perhaps after deleting that library; not sure if that's actually necessary)
cd libs/my_boost_lib/build
../../../b2
The latter works because b2 looks for a Jamfile.v2 in its current working directory, and that file exists and is intended to build just the library. The build results will be located outside of libs/my_boost_lib though.
Note: To build run the library tests, build the same way but from libs/my_boost_lib/test.
Essentially the build steps is
Run bootstrap to build the build tool b2
Build boost with b2 install or similar. You may want to provide options to it.
Read more in the boost getting started document:
http://www.boost.org/doc/libs/1_66_0/more/getting_started/index.html
(hint, look at lower right to go to next page..)
If you are on windows / VS2017, the use of vcpkg to get boost is very easy.
While trying to build the thrift c++ library, I came across the following error after specifying the --with-boost option.
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.
I looked through the boost documentation (which is I am not overly familiar with), but I did not find a good definition for the term staged boost library. I see the parenthetical (still not installed), but there are many states that are a library can be in that fall under the category of not installed.
When I first download boost, I run ./bootstrap and ./b2 to compile it.
Is it staged at this point? Or do I have to do something else to make it staged?
You can call
b2 --help
to see options of Boost.Build, and there you can find
install Install headers and compiled library files to the
======= configured locations (below).
...
stage Build and install only compiled library files to the
===== stage directory.
The declaration of stage or install specifies whether the Boost Libraries are installed in a subfolder named stage or system-wide. The meaning of system-wide depends on the operating system. In Windows, the target directory is c:\boost, in Linux it is /usr/local. The target directory can also be explicitly specified using the -–prefix option. Also see this answer, I guess it will be helpful.
For more informations see Getting Started Guide for Windows or Linux.
When you run .\b2 to compile Boost, it create a folder called stage and output of the compilation is put inside %BOOST_ROOT%\stage\lib folder. Now you can copy this lib folder somewhere and add that in to linker's path. However some projects might expect binaries to be available at stage\lib. So "staged" here means if you have libraries compiled and present in stage\lib folder. The .b2 command takes several different parameters to compile different kids of binaries, for example, below compiles binaries that are linked to shared runtime and targeting x64 architecture:
b2 variant=debug,release link=shared runtime-link=shared address-model=64
Each variant of lib file name has tags so they don't overwrite each other, for example, libboost_date_time-vc140-mt-gd-1_62.lib.
I've recently got acquainted with Boost library and I'd like to use it in my Xcode project. But sadly there is no HowTo or FAQ on how to do it :(
What's the sequence of actions to build and use Boost libraries in Xcode?
The easiest way I've found to do it is to install MacPorts, then you can install/build Boost via a single command:
sudo port install boost
Plus you get similar access to other open source software. The only downside I've found is that, like any other package management system, they are not always up to date with the latest version.
If you prefer Homebrew as your package manager, the command is:
brew install boost
I don't know how to use Boost from XCode (I'm not a Mac programmer), but building boost is usually done through their own build tool, bjam.
They have a guide to building boost here, and you can download the latest version of bjam here
Once it is built, you reference it from Xcode the same way you would any other library. The boost/include should be added to your include path, and the libraries in boost/lib can be referenced for the boost libs that require it.
To build boost on a mac, follow the unix variants getting started page (http://www.boost.org/doc/libs/1_39_0/more/getting_started/unix-variants.html). You won't use Xcode directly to perform the build, but once complete you can add the boost include paths and dylib's to your Xcode project.
I found that to build Boost 1.41.1 on MacOS, you need to do the following:
Download boost 1.46.1 from here: http://sourceforge.net/projects/boost/files/boost/1.46.1/
Unpack the file
Open terminal, cd to the install directory, and do the following:
chmod u+x configure.sh
cd tools/build/v2/engine/src
chmod u+x build.sh
Then go back to the install directory, and:
./configure.sh
If that runs successfully, it will tell you to run:
./bjam
That's it.. for whatever reason, I needed to set those permissions manually before it would work.
su - root
enter root password and then run below as root
/opt/local/bin/port install boost
If you have never logged in as root or forgotten your password, here are the steps to reset root password

For most of the boost libraries, there's nothing to build, it's all in header files.
The remainder of the instructions are here.
Currently I'm very happy with using Pete Goodliffe's script which builds a framework from the Boost source package for both iOS and Mac. Drag and drop it into a project and it works!
There are multiple versions of the script out there. Here's one:
https://gist.github.com/faithfracture/c629ae4c7168216a9856/61be257e1c0839c85743777d0687becad9913bf7
Elaboration of Ferrucio's answer:
Install Boost using MacPorts (sudo port install boost) or Homebrew (brew install boost).
Find the path to the Boost header files (it should be in /opt/homebrew/include if you're using Homebrew).
Add the path to System Header Search Paths in the Build Settings of your Xcode target.
IMPORTANT NOTE: If you add the path to User Header Search Paths instead of System Header Search Paths, as other users suggested, then your code will fail to build, since the Boost files use angled-includes (#include <boost/filename.hpp>) to include each other. Angled-includes are only for including system library headers, and thus they only work if Boost is in the System Header Search Paths.
You can read about the difference between angled-includes and quoted-includes here.
