Note: Actually the version of fftpack on netlib is slightly different. This version is a double-precision version. If you want to compile it with a Fortran compiler (the original source), either use IMPLICIT statements, or get the Fortran source from: netlib/bihar The command used to generate the C source was `f2c *.f' To make: 1) Type `./configure' The options configure will recognize: --with-prefix=install_prefix_pathname --with-cc=full_cc_pathname --with-ld=full_ld_pathname --with-ar=full_ar_pathname --with-ranlib=full_ranlib_pathname These options are designed to allow users to specify alternate programs to use so that cross compiling can be performed. If you are compiling this library for a native platform then you should not need to specify any options. 2.) Type `make' 3.) Type `make -n install' The default installation directory is `/usr/local/lib'. If you wish to install the library in another directory the do: make -n install prefix=/usr/wherever/lib 3a) If you are satisfied with the "make install" command output, then retype the command without the `-n'.
