Re: [Discuss-gnuradio] Re: Intel Mac GNU Radio Install Update Soon

[Thomas Schmid]

Hi Michael,

Thanks a lot for writing that install guide for Mac OS X. It works
great. Here some updates on my experience with it on a Macbook 2GHz
with XCode 2.3:

- The USRP section is outdated. You don't need to download it
seperatly since the checkout script has been changed.
- Since the new Macbooks have dual core, one can add a -j2 to each
make command. That will speed up compilation because it creates two
gcc instances at a time.
- I converted the tcsh scripts to bash. Here is what I have in my
.profile. This assumes that you use darwinports:

export LDFLAGS="-L/opt/local/lib ${LDFLAGS}"
export PATH=/opt/local/bin:${PATH}
export MANPATH=/opt/local/share/man:${MANPATH}
export INFOPATH=/opt/local/share/info:${INFOPATH}
export CPATH=/opt/local/include:${CPATH}
export 
PKG_CONFIG_PATH=/opt/local/lib/pkgconfig:/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}

p_v_f=`python -V 2>&1 | sed -e 'address@hidden @@g' | sed -e 'address@hidden@ 
@2' |
awk '{print $1}'`
export PYTHON_VERSION=$p_v_f
export PYTHON_ROOT=`which python | sed -e 's@/bin/python@@g'`
export PYTHONPATH=${PYTHON_ROOT}/lib/python${PYTHON_VERSION}/site-packages
if [ ${PYTHON_ROOT} != "/usr/include" ]; then
   export 
PYTHONPATH=${PYTHONPATH}:/usr/local/lib/python${PYTHON_VERSION}/site-packages
fi


Could that howto install script maybe be moved into the wiki, once the
new wiki system is up and running?
