This document describes how to make existing ELiPS library working in Linux environment. This is expected that it will work any 32-bit and 64bit Unix distribution Ububtu, OS X (not tested). Autotools installation may vary for Linux and OS X. Please keep in mind that it is still in developing phase. If found any bug related to installation, please infrom in [email protected]

1. Follow the instructions to install GMP library. Latest vesion is ok.

2. Check if autoconf is installed in your environment. autoconf --version. You migh see someting like this . If it is not installed then follow point 3. autoconf (GNU Autoconf) 2.69 Copyright (C) 2012 Free Software Foundation, Inc.

3. Install autoconf as follows sudo apt-get update sudo apt-get install autoconf

4. Install libtool as follows sudo apt-get install libtool-bin

5. git clone https://github.com/eNipu/elips_bn_bls.git

6. From terminal enter to <elips_bn_bls> directory.

7. Run the following commands autoreconf -i

The output will be almost as follows

libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
libtoolize: and rerunning libtoolize and aclocal.
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
libtoolize: 'AC_PROG_RANLIB' is rendered obsolete by 'LT_INIT'
configure.ac:7: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
configure.ac:7: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation 

8. Next run ./configure
9. Then make
10. Finally sudo make install
11. To uninstall sudo make uninstall from the directory

Still there is no single header. Therefore please /usr/local/include/ELiPS_bn_bls directory to get the header declaration.

If you face cannot open shared object file: No such file or directory while running then follow this steps:

1. Run from terminal sudo ldconfig

2. echo $LD_LIBRARY_PATH

3. If the command of point 2 gives blank result then LD_LIBRARY_PATH=/usr/local/lib

4. Check if again of echo $LD_LIBRARY_PATH. If path is set then run again.
