universe@264: ---
universe@259: 
universe@760: The build processes uses configure and make.
universe@259: First, download the source code from [Source Forge][1].
universe@259: 
universe@259:     wget https://sourceforge.net/projects/ucx/files/ucx-latest.tar.gz
universe@259:     tar -xzf ucx-latest.tar.gz
universe@259:     cd ucx-latest
universe@390: 
universe@760: Then execute ./configure with the options you like. You can get a list of
universe@760: all available options with ./configure --help. The recommended configuration
universe@760: for production builds is ./configure --release.
universe@760: 
universe@760:     ./configure --release
universe@760:     make
universe@760:     make check                 # only available when built with tests 
universe@760:     sudo make install
universe@390: 
universe@737: When compiling UCX 3, you can tweak the buffer sizes for small-buffer-optimization.
universe@737: You can do this, be pre-defining one or more of the following macros:
universe@737: 
universe@737: --------------------------------- --------------------------------------------------------------------- ----------
universe@737: Macro                             Description                                                           Default
universe@737: --------------------------------- --------------------------------------------------------------------- ----------
universe@737: CX_ARRAY_SWAP_SBO_SIZE            The maximum item size in an array list that uses SBO.                 128
universe@737: 
universe@807: CX_LINKED_LIST_SWAP_SBO_SIZE      The maximum item size that uses SBO swap instead of relinking.        128
universe@807: 
universe@737: CX_LINKED_LIST_SORT_SBO_SIZE      The maximum list size that uses SBO during sort.                      1024
universe@737: 
universe@737: CX_PRINTF_SBO_SIZE                The maximum string length printf.h uses stack memory for.             512
universe@737: 
universe@806: CX_STRSTR_SBO_SIZE                The maximum length of the "needle" in cx_strstr that can use SBO.     512
universe@737: --------------------------------- --------------------------------------------------------------------- ----------
universe@737: 
universe@737: You can also tweak some other buffer sizes with the same technique:
universe@737: 
universe@737: --------------------------------- --------------------------------------------------- ----------
universe@737: Macro                             Description                                         Default
universe@737: --------------------------------- --------------------------------------------------- ----------
universe@737: CX_STRREPLACE_INDEX_BUFFER_SIZE   The number of matches one index buffer can store.   64
universe@737: 
universe@737: CX_STREAM_COPY_BUF_SIZE           The buffer size on the stack for a stream copy.     1024
universe@737: 
universe@737: CX_STREAM_BCOPY_BUF_SIZE          The buffer size on the heap for a stream copy.      8192

universe@390: ### UCX 2.1
universe@390: 
universe@390: The build procedure for UCX 2.1 uses a configure script.
universe@390: For Microsoft Windows, you will need an appropriate port of the linux
universe@390: tools (like MinGW or Cygwin).
universe@390: First, download the source code from [Source Forge][1].
universe@390: 
universe@390:     wget https://sourceforge.net/projects/ucx/files/ucx-2.1.0.tar.gz
universe@390:     tar -xzf ucx-2.1.0.tar.gz
universe@390:     cd ucx-2.1.0
universe@259: 
universe@259: Then issue the `configure` and `make` commands.
universe@259: 
universe@259:     ./configure && make
universe@259: 
universe@259: To verify your installment you can issue `make check`. If everything is fine,
universe@259: you can install UCX with
universe@259: 
universe@259:     make install
universe@259:     
universe@259: Note, that you might need administrative privileges for a system wide
universe@259: installation.
