This library is a C++ template library and, as such, there is no library to build and install. Copy the .h files and use them! See http://code.google.com/p/cpp-btree/wiki/UsageInstructions for details. ---- To build and run the provided tests, however, you will need to install CMake, the Google C++ Test framework, and the Google flags package. Download and install CMake from http://www.cmake.org Download and build the GoogleTest framework from http://code.google.com/p/googletest Download and install gflags from https://code.google.com/p/gflags Set GTEST_ROOT to the directory where GTEST was built. Set GFLAGS_ROOT to the directory prefix where GFLAGS is installed. export GTEST_ROOT=/path/for/gtest-x.y export GFLAGS_ROOT=/opt cmake . -Dbuild_tests=ON For example, to build on a Unix system with the clang++ compiler, export GTEST_ROOT=$(HOME)/src/googletest export GFLAGS_ROOT=/opt cmake . -G "Unix Makefiles" -Dbuild_tests=ON -DCMAKE_CXX_COMPILER=clang++
