Install Instructions for libsamplerate ====================================== The following instructions explain how to install libsamplerate under Linux and other Unix-like systems, including macOS. (For Windows, see http://libsndfile.github.io/libsamplerate/win32.html). Preliminaries ------------- 1) Included with libsamplerate are example programs which use libsndfile: http://libsndfile.github.io/libsndfile/ for file I/O. If you want to build them, you need to ensure that libsndfile is correctly installed first. If it is, the command "pkg-config --cflags --libs sndfile" should print out something like this: -lsndfile If pkg-config doesn't exist, you will need need to install it. If pkg-config cannot find libsndfile, you may need to install it. If you install from from a Linux distribution package, make sure you also install the libsndfile-devel package which contains the header files. If libsndfile is installed, you may need to set the PKG_CONFIG_PATH environment variable. If libsndfile is installed in /usr/local/lib, you will need to set PKG_CONFIG_PATH using: export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig 2) The included tests suite for libsamplerate needs libfftw3 which is available here: http://www.fftw.org/ If FFTW3 is not available, libsamplerate should still compile and install without problems, but the test suite will not be as comprehensive as it normally is. Building -------- Building and verifying libsamplerate is a four or five step process. 1) The first step is to run configure ./configure which should print out something like the following: checking build system type... ... ... -=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=- Configuration summary : Version : ..................... X.Y.Z Enable debugging : ............ no Tools : Compiler is GCC : ............. yes GCC major version : ........... 3 Extra tools required for testing and examples : Use FFTW : .................... yes Have libsndfile : ............. yes Installation directories : Library directory : ........... /usr/local/lib Program directory : ........... /usr/local/bin Pkgconfig directory : ......... /usr/local/lib/pkgconfig Compiling some other packages against libsamplerate may require the addition of "/usr/local/lib/pkgconfig" to the PKG_CONFIG_PATH environment variable. There are a number of configure options. See the output of configure when run with the --help command line option. 2) If all goes well with the above then compiling the library can be done with make 3) When that has finished, the test suite can be run using: make check 4) The final step is to install the library. This step needs to be carried out as the root user (or with sudo): make install This command will by default install the library in the directory /usr/local/lib. It can be installed in other locations by using the --prefix option in step 1). 5) On Linux, one more step is required, the registering of the library with the system. This is done by running the following command (also as the root user): ldconfig -v
