The libraries are aimed at a wide range of C++ users and application domains. They range from general-purpose libraries like the smart pointer library, to operating system abstractions like Boost FileSystem, to libraries primarily aimed at other library developers and advanced C++ users, like the template metaprogramming (MPL) and domain-specific language (DSL) creation (Proto).
The original founders of Boost that are still active in the community includes David Abrahams. An author of several books on C++, Nicolai Josuttis, contributed to the Boost array library in 2001. There are mailing lists devoted to Boost library use and library development, active as of 2023[update].[10]
As a C++ newcomer I often hear about Boost, however most of the things I already find in `std` or extracted like ASIO. What are some good libraries I am missing? For example I was interested in metaprogramming and found Boost.Hana but it seems like modern C++ metaprogramming is much easier and the library might be a bit obsolete..?
I tried to use Boost with unreal engine, using UE4 build system, as stated above, but run into problems very soon. Reason for using boost in my case is advanced logging. I need to use boost logging, which is not in header files, but in binary libs. In advance, it requires RTTI to be enabled. This, however not pleasant, is not hard to achieve by placing bUseRTTI = true; into build.cs file.
Right now, I have spent some 14 hours of trying to make this work, and right now I am totally out of ideas. If anybody managed to made boost run with UE4(4.9 using VS 2013), I would be more than glad if You could help me.
If all you want are the boost headers its fairly straight forward. Here: GitHub - NullP0inter/UE4_Boost is an example of the headers working. The TestingGrounds level blueprint calls the testGraph method defined in BoostTestFunctionLibrary and you can see the output in the log. I pulled the graph example from the boost website.
Please refer to this Article for the installation of boost. We can download the zip file. After that, we just need to extract the whole in a specified folder of gcc or we can do this easily by command prompt.
We can efficiently use this library in Competitive Programming but before this, we must ensure that your online judge must support boost. Here are some cool tricks that you can use:
I already got through with the compilation. I just had to install a couple of libboost devel packages such as libboost_headers1_66_0-devel and libboost_mpi_python-py3-1_66_0-devel for the Python serialization libraries. Thanks for pointing out the devel packages.
I am trying to build ros hydro from source on ubuntu 12.04 it requires boost 1.46.1 but the version of boost installed on my machine is 1.48 so I downloaded boost 1.46.1 and installed it in a local folder. I also added skip-keys flag in rosdep to stop it from installing boost (because it would remove the newer version). After installing these dependencies I did ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release as mentioned here :
I specified the boost library path using CMAKE_LIBRARY_PATH variable cmake is able to find the local boost installation using this.I also tried changing the CMakeCahe.txt file in tf package by specifying the location of libboost_thread.so but still no luck can someone please help .
Some time ago I already asked a question about the integration of the Boost library. At that time I did not fully understand the concept. Afterwards I was able to integrate the library under Visual Studio.
We are using SonarQube 8.8.0.42792 Developer Edition to analyse a huge C++ code base. Till now everything was working like a charm. Recently we added Boost library and starting compiling it as a part of the project due to internal requirements. As a result SonarQube (with build-wrapper 6.18.0.29274) and specifically sonar-scanner (sonar-scanner-4.6.0.2311-linux) fail while analyzing even simplest code using boost library. We use Boost 1.79.0 version which was released on 17th March 2022. This is an example app where the analysis fails:
I cannot confirm without investigation if this specific crash is fixed. Looking at how simple the code is, I would guess that it was fixed since we are no longer getting any reports about boost crashes. A candidate ticket: [CPP-2696] - Jira.
This module first searches for the Boost header files using the abovehint variables (excluding BOOST_LIBRARYDIR) and saves the result inBoost_INCLUDE_DIR. Then it searches for requested component librariesusing the above hints (excluding BOOST_INCLUDEDIR andBoost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR,and the library name configuration settings below. It saves thelibrary directories in Boost_LIBRARY_DIR_DEBUG andBoost_LIBRARY_DIR_RELEASE and individual librarylocations in Boost__LIBRARY_DEBUG and Boost__LIBRARY_RELEASE.When one changes settings used by previous searches in the same buildtree (excluding environment variables) this module discards previoussearch results affected by the changes and searches again.
Set to ON to resolve symlinks for discovered libraries to assist withpackaging. For example, the "system" component library may be resolved to/usr/lib/libboost_system.so.1.67.0 instead of/usr/lib/libboost_system.so. This does not affect linking and shouldnot be enabled unless the user needs this information.
On Visual Studio and Borland compilers Boost headers request automaticlinking to corresponding libraries. This requires matching librariesto be linked explicitly or available in the link library search path.In this case setting Boost_USE_STATIC_LIBS to OFF may not achievedynamic linking. Boost automatic linking typically requests staticlibraries with a few exceptions (such as Boost.Python). Use:
If Boost was built using the boost-cmake project or from Boost 1.70.0 onit provides a package configuration file for use with find_package's config mode.This module looks for the package configuration file calledBoostConfig.cmake or boost-config.cmake and stores the result inCACHE entry Boost_DIR. If found, the package configuration file is loadedand this module returns with no further action. See documentation ofthe Boost CMake package configuration for details on what it provides.
I am trying to playing with matrices in root.
Since I experienced some issues using TMatrix and SMatrix (Resizing and transposing a TMatrixFSparse - row/col indices are not set, Cannot transpose a TMatrixFSparse matrix - Error in : matrix has wrong shape, TMatrix for large matrices, Using SMatrix for large matrices) so I used the boost library after the suggestion of @Wile_E_Coyote
As the error says "New Boost version may have incorrect or missing dependencies and imported", So we suspect the version of the boost library downloaded and copied is not 1.72.0 or earlier, which is what supported by the toolchain. Looks like the version you downloaded is 1.75.0.
For a client I needed to add boost 1.54 to the system. So I downloaded the latest version (1.55) and built it within a special directory: /usr/local/lib/boost1.55/. This works. Then I had to adapt the Makefile in this way.
LIBS = $(SUBLIBS) -L/usr/lib/x86_64-linux-gnu -LC:/deps/miniupnpc -lminiupnpc -lqrencode -lrt -LC:/deps/boost/stage/lib -Lc:/deps/db/build_unix -Lc:/deps/ssl -LC:/deps/libqrencode/.libs -lssl -lcrypto -ldb_cxx -L/usr/local/lib/boost1.55/boost_system-mgw46-mt-sd-1_54 -L/usr/local/lib/boost1.55/boost_filesystem-mgw46-mt-sd-1_54 -L/usr/local/lib/boost1.55/boost_program_options-mgw46-mt-sd-1_54 -L/usr/local/lib/boost1.55/boost_thread-mgw46-mt-sd-1_54 -lQtDBus -lQtGui -lQtCore -lpthread -lboost_system -lboost_filesystem -lboost_program_options -lboost_thread
This is because your binary is using dynamic libraries. So when the binary was compiled, it was against the 1.55 versions of the libraries. However when you interrogate the binary using ldd, it's within the environment that's using the contents of the .cache file. So the library within the cache that is associated with the symbols used by this binary match those for 1.53, hence you're seeing those libraries.
Think of the functions within these as symbols. The symbols are a name, and so these names often don't change from one version of a library to another. So if you were to look at a library such as boost, you can use the tool readelf to get a list of the symbols within one of these .so files.
If you have compiled your own software and installed it outside of the library search paths, you'll need to compile the binaries with a hard-coded RPATH. This is done by passing -rpath to your linker. However, most of the time, your Makefile doesn't run the linker directly, you need to tell gcc to pass it to the linker, typically by adding -Wl,-rpath,/usr/local/whatever/lib to the CFLAGS.
If you don't want to hard-code paths, you can update your $LD_LIBRARY_PATH environment variable to have a comma delimited collection of library directories you want to prepend to the runtime library search path. Setting $LD_LIBRARY_PATH is ephemeral, it does nothing to the binary, so you'd need to set it any time you need to run the executable. (See Environment Modules if you want to do this in a regular manner)
Clone Boost and setup for building. Please note this is a one-time operation that will take some time as it brings down all of the Boost sources. Throughout this post it is assumed you cloned into C:\boost.
Once built, the binaries are output under the bin.v2 folder. The exact location is dependent on the options used and the name of the library built. For the command from before used to build Boost.Thread the binaries are located under:
Snippets - code templates one line or longer - boost researcher productivity because they are faster to insert than writing the code from scratch and because they reduce debugging time. Several extensions support the use of snippets in Jupyter. We developed a Python version of the pymolsnips library and customized it for use in the jupyterlab-snippets-multimenus extension for JupyterLab. The extension provides access to the snippets by pull-down menus. Each snippet performs one task. Each task often requires many lines of code. This library's availability in Jupyter enables PyMOL users to run PyMOL efficiently inside Jupyter while storing the code and the associated molecular graphics images next to each other in one notebook document. This proximity of code and images supports reproducible research in structural biology, and the use of one computer file facilitates collaborations.
