4) Build and install the ilcsoft
4-0) Set default compilers to clang
$ sudo alternatives --config gcc
	select clang!


4-1) First install base packages.
$ cd /Users/proj/soft/ilcsoft/clang
$ tar -zxvf src/10.15/v02-01/ilcinstall.02.01.tar.gz
$ cd ilcinstall.02.01
$ patch -p1 -s -b < ../src/10.15/v02-01/ilcinstall-v02-01-clang.patch
$ ./ilcsoft-install -i releases/v02-00/release-base.cfg
$ pushd ../root/6.20.00/
$ patch -p1 -s < ../../src/10.15/v02-01/root-v6.20.00-cmake.patch
$ popd
$ pushd ../geant4/10.06/lib
$ ln -s Geant4-10.6.0 Geant4-10.6
# Note:
# - The symlink, Geant4-10.6 is necessary to let cmake find Geant4Config.cmake.


4-2) Then install ilcsoft packages
$ ./ilcsoft-install -i releases/v02-00/release-osx.cfg
.......

... before compilation starts, apply the following patches in a new window:
... Open a new terminal and do the following

$ pushd ../v02-01/MarlinUtil/v01-15-01/
$ patch -p1 -s < ../../../src/10.15/v02-01/marlinutil-v01-15-01-c++17.patch
$ popd
$ pushd ../v02-01/ILDPerformance/v01-07/
$ patch -p1 -s < ../../../src/10.15/v02-01/ildperformance-v01-07-unistd.patch
$ popd
$ pushd ../v02-01/ForwardTracking/v01-14/
$ patch -p1 -s < ../../../src/10.15/v02-01/forwardtracking-v01-14-notest.patch
$ popd
$ pushd ../v02-01/MarlinTPC/v01-04/
$ patch -p1 -s < ../../../src/10.15/v02-01/marlintpc-v01-06-not0.patch
$ patch -p1 -s < ../../../src/10.15/v02-01/marlintpc-v01-06-eigen.patch
$ patch -p3 -s < ../../../src/10.15/v02-01/marlintpc-rootfileproc.patch
$ popd
$ pushd ../v02-01/lccd/v01-05/
$ patch -p1 -s < ../../../src/10.15/v02-01/lccd-v01-05-c++17.patch
$ popd
$ pushd ../v02-01/Clupatra/v01-03/
$ patch -p1 -s < ../../../src/10.15/v02-01/clupatra-v01-03-c++17.patch
$ popd
$ pushd ../v02-01/FCalCluster/v01-00-01/
$ patch -p1 -s < ../../../src/10.15/v02-01/fcalcluster-v01-00-01-c++17.patch
$ popd
$ pushd ../v02-01/KalTest/v02-05/
$ patch -p1 -s < ../../../src/10.15/v02-01/kaltest-v02-05-c++17.patch
$ popd


# Note:
# c++17 removed mem_fun, find2nd, register supports.
# unistd patch includes unistd.h to define R_OK and W_OK.
--------------------------------------------------------------
To rebuid a package after modifiying the source code:
$ cd <package dir>
$ touch .install_failed.tmp
--------------------------------------------------------------


5) Test run
# I had to add all the relevant lib directories to DYLD_LIBRARY_PATH
# in init_ilcsoft.sh
# I also had to reboot the system with Cmd+R (or Opt+Cmd+R) and do
# the following to allow DYLD_LIBRARY_PATH
# csrutil disable


6) KalTest in Xcode
6-1) Build root with clang++
$ sudo alternatives --config gcc
  .. to select clang
$ cd <KalTest test directory>
$ mkdir root
$ cd root
$ tar -zxvf <source file directory>/root_v6.20.00.source.tar.gz
$ cd mv root-6.20.00 6.20.00
$ cd 6.20.00
$ mkdir build_root
$ cd build_root
$ cmake -DCMAKE_INSTALL_PREFIX=`pwd`/.. ..
$ make -j8
$ make install

6-2) Then build ilcutil with that root
$ cd <KalTest test directory>
$ mkdir ilcutil
$ cd ilcutil
$ tar -zxvf <source file directory>/ilcutil-v01-05.tar.gz
$ cd v01-05
$ mkdir build
$ cd build
$ source ../../../root/6.20.00/bin/thisroot.sh
$ cmake ..
$ make
$ make install

6-3) Prepare Xcode project for KalTest
$ cd <KalTest test directory>
$ mkdir kaltest
$ tar -zxvf <source file directory>/kaltest-v02-03.tar.gz
$ cd v02-03
$ mkdir build
$ source ../../root/6.20.00/bin/thisroot.sh
$ cmake -G Xcode -DILCUTIL_DIR=<ilcutil source directory> ..

6-4) Build and run KalTest with Xcode
# v02-04 does not work (no display)
# reverted to v02-03



-----------<Obsolete>-----------------------------------------
To get the head version do the following, instead:
$ svn co https://svnsrv.desy.de/public/marlintpc/trunk


5) Then build and install MarlinTPC
If you have libjpeg-devel and libtiff-devel installed,
uninstall them since they conflict with the system 
provided libraries:

$ rpm -e libjpeg-devel libtiff-devel

Then build MarlinTPC:

$ cd /Users/proj/cdc/soft/MarlinTPC
$ tar -zxvf src/r3390.tar.gz
$ cd r3390
$ tar -zxvf ../src/analysis.tar.gz
$ mkdir build
$ cd build
$ cmake -C ../../../v01-17-04/ILCSoft.cmake ..
$ make install
$ cd ..
$ tar -zxvf ../src/LP_Asian_GEM_Module.tar.gz -C examples


7) You can also try CEDViewer
In order to use CEDViewer, you need to start a CED server, glced, first.
$ source ../../../v01-17-04/init_ilcsoft.sh
$ glced -world_size=100.

Then open a new termnal window and type
$ cd /Users/proj/cdc/soft/MarlinTPC/r3390/examples/LP_Asian_GEM_Module
$ Marlin reconstructLCTPCRawData.xml

Hit "h" in the viewer window for "help".



In order to get trunk version of ilcsoft, first get the trunk version
of ilcinstall by typing

$ svn co https://svnsrv.desy.de/public/ilctools/ilcinstall/trunk
