Instructions to build MATHLIB from source:

1. Clone MATHLIB from git://git.ti.com/ep-processor-libraries/mathlib.git 
   Clone SWTOOLS from git://git.ti.com/ep-processor-libraries/swtools.git

2. Make sure following Proc-SDK components are installed:
   - SYSBIOS
   - XDC
   - Code Gen Tools
   - CCS

3. Setup following environment variables (exact version numbers may be different):
export SYSBIOS_INSTALL_DIR="<COMPONENTS_INSTALLATION_ROOT>/bios_6_52_00_12"
export XDC_INSTALL_DIR="<COMPONENTS_INSTALLATION_ROOT>/xdctools_3_50_03_33_core/"
export XDCCGROOT="<COMPONENTS_INSTALLATION_ROOT>/ti-cgt-c6000_8.2.2"
export CGTROOT="<COMPONENTS_INSTALLATION_ROOT>/ti-cgt-c6000_8.2.2"
export C64PCODEGENTOOL="${CGTROOT}"
export C674CODEGENTOOL="${CGTROOT}"
export C66CODEGENTOOL="${CGTROOT}"

export CCSVERSION="CCSV8"
export CCS_INSTALL_DIR="<COMPONENTS_INSTALLATION_ROOT>/ccsv8"

export SWTOOLS_INSTALL_DIR="<SWTOOLS git clone root>"
export SWTOOLS_PATH="<SWTOOLS git clone root>/ti/mas/swtools"
export MATHLIB_ROOT_DIR="<MATHLIB git clone root>"
export XDCBUILDCFG="${SWTOOLS_PATH}/config.bld"

export PATH="${XDC_INSTALL_DIR}:${PATH}"

export XDCPATH="${XDC_INSTALL_DIR}/packages;${SWTOOLS_INSTALL_DIR};${MATHLIB_ROOT_DIR};${SYSBIOS_INSTALL_DIR}/packages;"

4. Build SWTOOLS and then MATHLIB
   - Go to directory <SWTOOLS_PATH> and issue command "xdc"
   - Go to directory <MATHLIB_ROOT_DIR>/ti/mathlib and issue one of following commands:
       - xdc XDCARGS="c66x bundle"
       - xdc XDCARGS="c674x bundle"
