libo is a library for managing OSC bundles and the odot-expression language, by John MacCallum.

Building libo

Mac

  1. Check out the libo repository
  2. Install flex and bison.
    • Compiling libo requires flex >2.5 and bison >2.4 to be installed. The OS X developer tools come with older versions of flex and bison which will not work.
    • Download the latest version of flex: http://flex.sourceforge.net
    • Download the latest version of bison: http://www.gnu.org/software/bison/
    • Follow the instructions that come with the source code---it should be the usual ./configure; make; sudo make install.
    • Be aware that Apple's versions of flex and bison are installed in /usr/bin and that the ones you install will likely end up in /usr/local/bin, so you will either have to remove Apple's, or adjust your path accordingly.
  3. Build libo
    1. Add the following lines to your .profile, changing 8 to match the version of your OS
      • MAC_SYSROOT = MacOSX10.8.sdk
      • export MAC_SYSROOT
    2. Execute the following commands at the command line:
      • $ cd <path/to/libo>
      • $ make

Windows

For building on Windows, we are working on Windows 10, using the MinGW-w64 complier on Cygwin64, with separate tool chains for 32 and 64 bit externals.

1. Cygwin64

Down and install Cygwin64, available here.

The Cygwin installation/setup program allows you to select install packages.

Once you arrive at the Select Packages page, set View to Full, and then search for the following packages. You will need to scroll down to find them sometimes.

select and install the following:

  • make : The GNU Version of the make utility.
  • gcc : GNU complier collection
  • mingw64-x86_64-gcc-core : GGC for Win64 toolchain
  • mingw64-i686-gcc-core : GGC for Win32 toolchain
  • flex : A fast lexical analyzer generator
  • bison : GNU yacc-compatible parser generator

(to select for installation, click the Skip icon which should then change to the version number)

On the following page, make sure select required packages is enabled.

2. GitHub repositories

git clone https://github.com/CNMAT/libo

3. build libo

To build for Windows 64bit, enter the libo directory and do:

make win64

This will compile the library with the win64 tool chain, and create a libo.a file in the /libo/libs/x86_64 folder.

Then to build the Windows 32bit version of the library do:

make clean
make win

This will compile the library with the win64 tool chain, and create a libo.a file in the /libo/libs/i686 folder.

Note we need to make clean before building the new version, otherwise the library will be created with the already complied .o files.
