4. Installation of OmpSs from git

Sometimes it may happen that you have to compile OmpSs from the git repository.

Note

There is no need to compile from git, you can always use a tarball. See Installation of OmpSs.

4.1. Additional requirements when building from git

• Automake 1.9 or better. Get it at http://ftp.gnu.org/gnu/automake
• Autoconf 2.60 or better. Get it at http://ftp.gnu.org/gnu/autoconf
• Libtool 2.2 or better. Get it at http://ftp.gnu.org/gnu/libtool
• Git. Get it at http://git-scm.com/download/linux

Note

It is likely that your Linux distribution or system already contains these tools packaged or installed. Check the documentation of your Linux distribution or ask your administrator.

4.2. Nanos++ from git

1. Make sure you fulfill the requirements of Nanos++. See Nanos++ build requirements.

2. Clone the Nanos++ repository:

   $ git clone http://pm.bsc.es/git/nanox.git
   Cloning into 'nanox'...
   remote: Counting objects: 22280, done.
   remote: Compressing objects: 100% (7567/7567), done.
   remote: Total 22280 (delta 17397), reused 18399 (delta 14290)
   Receiving objects: 100% (22280/22280), 3.50 MiB, done.
   Resolving deltas: 100% (17397/17397), done.
   

3. Run autoreconf in the newly created nanox distribution:

   $ cd nanox
   $ autoreconf -fiv
   autoreconf: Entering directory `.'
   autoreconf: configure.ac: not using Gettext
   autoreconf: running: aclocal --force -I m4
   autoreconf: configure.ac: tracing
   autoreconf: running: libtoolize --copy --force
   libtoolize: putting auxiliary files in `.'.
   libtoolize: copying file `./ltmain.sh'
   libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'.
   libtoolize: copying file `m4/libtool.m4'
   libtoolize: copying file `m4/ltoptions.m4'
   libtoolize: copying file `m4/ltsugar.m4'
   libtoolize: copying file `m4/ltversion.m4'
   libtoolize: copying file `m4/lt~obsolete.m4'
   autoreconf: running: /usr/bin/autoconf --force
   autoreconf: running: /usr/bin/autoheader --force
   autoreconf: running: automake --add-missing --copy --force-missing
   configure.ac:149: installing './ar-lib'
   configure.ac:153: installing './compile'
   configure.ac:10: installing './config.guess'
   configure.ac:10: installing './config.sub'
   configure.ac:15: installing './install-sh'
   configure.ac:15: installing './missing'
   Makefile.am: installing './INSTALL'
   src/apis/c/debug/Makefile.am: installing './depcomp'
   autoreconf: Leaving directory `.'
   

4. Now follow steps in Installation of Nanos++, starting from the step where you have to run configure.
