#### Get and build the Boinc libraries - Version 7.4.42 
#### Raspbian Jessie has Boinc version 7.4.23 available.

git clone https://github.com/BOINC/boinc boinc
cd boinc
git checkout client_release/7.4/7.4.42; git status
./_autosetup
./configure --disable-server --disable-manager LDFLAGS=-static-libgcc --with-boinc-alt-platform=arm-unknown-linux-gnueabihf

#### !  or current Boinc: ####
git clone https://github.com/BOINC/boinc boinc
cd boinc
./_autosetup
./configure --disable-server --disable-manager LDFLAGS=-static-libgcc --with-boinc-platform=arm-unknown-linux-gnueabihf

##### Now get the Seti_Boinc source, and build the app: ####

## working version 3304:
svn checkout https://setisvn.ssl.berkeley.edu/svn/seti_boinc@3304 seti_boinc
## current (do not compile):
#svn checkout https://setisvn.ssl.berkeley.edu/svn/seti_boinc seti_boinc

cd seti_boinc 

./_autosetup

./configure BOINCDIR=/root/boinc --enable-client --enable-static --disable-shared --disable-server --enable-dependency-tracking --with-gnu-ld --disable-altivec --enable-fast-math

make -j4

ls -l client
#if setiathome-8.0.armv7l-unknown-linux-gnueabihf exists, compilation has been successful.

#### App Setup:

cp ~/seti_boinc/client/setiathome-8.0.armv7l-unknown-linux-gnueabihf ~/
cd ~

#To build a tar.gz to move to another computer:
tar cvzf setiathome-8.0.armv7l-unknown-linux-gnueabihf.tar.gz setiathome-8.0.armv7l-unknown-linux-gnueabihf app_info.xml


#To install and run the app you just built on a Raspberry Pi, first install boinc-client:

sudo apt-get install boinc-client

#Next attach to the Seti project:

boinccmd --project_attach http://setiathome.berkeley.edu [YOUR KEY GOES HERE]


#Copy the app and the app_info.xml files to the project folder:

cp setiathome-8.0.armv7l-unknown-linux-gnueabihf /var/lib/boinc-client/projects/setiathome.berkeley.edu/
cp app_info.xml /var/lib/boinc-client/projects/setiathome.berkeley.edu/

#Change the file permissions to boinc:boinc:

chown boinc:boinc /var/lib/boinc-client/projects/setiathome.berkeley.edu/setiathome-8.0.armv7l-unknown-linux-gnueabihf
chown boinc:boinc /var/lib/boinc-client/projects/setiathome.berkeley.edu/app_info.xml

#Finally, restart boinc-client so it will use the new app:

/etc/init.d/boinc-client restart
