Compilation and Installation

Installation Directory

The installation directory is the directory to which all build products (header files, libraries, executables, and runtime data) will be installed when you type make install. The installation directory is set when you run the configure script, and is stored in the Makefile variable, $prefix. When you type make install, build products are installed in

$prefix/include
$prefix/lib
$prefix/bin
$prefix/share

There are currently three ways in which the installation directory can be specified:

$PSRHOME environment variable: if set, then installation directory will be set to $PSRHOME/$LOGIN_ARCH.
Command line: the install directory may be specified using the --prefix argument to the configure script; e.g.

./configure --prefix=$HOME/Pulsar

Default: If the $PSRHOME environment variable is not set, and the --prefix argument is not used, then the installation directory will default to /usr/local/dspsr.

Configure the build

To configure the compilation and installation of DSPSR, run the configure script; e.g.

./configure

will configure the compilation of static libraries. To compile shared object libraries that can be dynamically loaded at runtime,

./configure --enable-shared

Compile, run tests, and install

When satisfied that the configure script has found all of the desired dependencies, run

make
make check
make install

The make check step tests a number of runtime features in the software, and can expose a variety of potential problems, such as differences in how compilers handle the code, how FFT libraries scale their output, etc.
