1. Create a new iPhone Window-based application project “SampleTest”.

2. Our subject for testing is Converter.m which converts kilometers to meters. Let’s implement an incorrect conversion by specifying 1km = 100 meters (should be 1000 meters) so we can see that the unit test captures it below…

#import "Converter.h"
 
@implementation Converter
 
- (id)init{
	if(self = [super init]){
 
	}
	return self;
}
 
- (int)convertKilometersToMeters:(int)km{
	return km * 100;
}
 
@end

3. Add another target “UnitTests”. Right click on Targets -> Add -> New Target… -> Choose Unit Test Bundle.

4. Name it “UnitTests”. After hitting submit, you will be presented with the project settings for “UnitTests”.

5. Go to the General Tab -> Click on the “+” icon above “Linked Libraries”. Choose “SampleTest” as the application we have direct dependency with.

6. Close the Settings. To check, navigate under “Groups & Files” -> Targets. You should see the SampleTest Application Icon just below “UnitTests”.

7. Right Click on “Sample Test” -> Add -> New File…

8. Name the file “ConverterTest. Don’t forget to also create the header file (default). Specify it also in a different directory under “Location”. Then check the UnitTests as the “Targets”. When you hit “Finish” it will ask you to create the folder “Tests”

Tip: Keep things organize and put it under a “Tests” Group. Right Click on “Sample Test” -> Add -> New Group… Name it “Tests”, then drag the files (ConverterTest.h and ConverterTest.m) into that group.

9. Open up ConverterTest.h and notice that “SenTestingKit.h” is already imported. Now let’s add method testKilometersToMeters as shown below. Test methods usually start out with a test prefix.

In the implementation, let’s import Converter.h and use STAssertTrue. To test the convertKilometersToMeters method, we are asserting that the result should be 1000. If not, then we should know! That is why we are writing a unit test for.. making sure that our implementation doesn’t break.

#import "ConverterTest.h"
#import "Converter.h"
 
@implementation ConverterTest
 
- (void)testKilometersToMeters{
	int km = 1;
	Converter *converter = [[Converter alloc] init];
	int meters = [converter convertKilometersToMeters:km];
	STAssertTrue(meters == 1000, @"converting %d km to meters should equal 1000, instead received %d", km, meters);
}
 
@end

12. Now, before we build our target “UnitTests”, we need to include additional class references from our application. Drag Converter.m to the “Compile Sources” under UnitTests.

13. Now we can build. There are many ways to do this. My preference is to do a clean build when testing. Right Click on Sample Test then choose “Clean SampleTest”. Afterwards choose “Build SampleTest”.

If you have a succesful build for SampleTest, lets do the same for our “UnitTests”.

13. Here’s the crux of it. Notice the error in your “Build Results”?

/Users/rupert/projects/iphone/SampleTest/Tests/ConverterTest.m:18: error: -[ConverterTest testKilometersToMeters] : "meters == 1000" should be true. converting 1 km to meters should equal 1000, instead received 100

Now changing the correct implementation of convertKilometersToMeters will put the error away and you will have a successful build.

- (int)convertKilometersToMeters:(int)km{
	return km * 1000;
}

14. Look up the assert methods from SenTest.h.

#import <Foundation/NSObject.h>
#import "SenTest.h"
 
#define STAssertNil(a1, description, ...)
#define STAssertNotNil(a1, description, ...)
#define STAssertTrue(expression, description, ...)
#define STAssertFalse(expression, description, ...)
#define STAssertEqualObjects(a1, a2, description, ...)
#define STAssertEquals(a1, a2, description, ...)
#define STAssertEqualsWithAccuracy(left, right, accuracy, description, ...)
#define STAssertFalseNoThrow(expression, description, ...)
....

Trying to figure out which version of the java applet being used by FF

Deleting the cache.. Go to

If the problem still persist, I bet we can trim down which java versions to use…

2. Install Oracle Instant Client on Mac.

a. Instant Client Package – Basic: All files required to run OCI, OCCI, and JDBC-OCI applications
- instantclient-basic-macosx-10.2.0.4.0.zip (34,020,719 bytes)

b. *Instant Client Package – SDK: Additional header files and an example makefile for developing Oracle applications with Instant Client
instantclient-sdk-macosx-10.2.0.4.0.zip (603,493 bytes)

OR download the whole bundle (10.2.0.4.zip) with sqlplus installed from my installers.

3. Put this on your sudo vim ~/.bash_profile.

export ORACLE_HOME=/Library/Oracle/instantclient/10.2.0.4
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME

4. Make a symbolic link

cd /Library/Oracle/instantclient/10.2.0.4
ln -s libclntsh.dylib.10.1 libclntsh.dylib

5. Go to /Library/Oracle/instantclient/10.2.0.4 and edit tnsnames.ora. Point the Oracle SID to the IP where you installed Oracle.

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.155)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )   
  )
 
 
ORCL_2_11 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.11)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )   
  )

6. Install the oracle-adapter for rails

sudo gem install activerecord-oracle-adapter --source http://gems.rubyonrails.org

7. In your database.yml file

development:
  adapter: oracle
  database: orcl
  username: youzhu_mobile_dev
  password: your_password

or browse the contents of a sample rails project youzhumobile.tar.gz

8. If you ever encounter an encoding problem, then we need to set the NLS_LANG environment variable before running script/server.

# export NLS_LANG=American_America.UTF8
# script/server

or I prefer setting it in the environment.rb

Rails::Initializer.run do |config|
  ENV['NLS_LANG']='American_America.UTF8'
  # Settings in config/environments/* take precedence over those specified here.

Note: If you don’t know your database encoding, then read this post.

2. You can drag an image from a browser right to your desktop. This is faster than doing [Command] + [SHIFT] + F4 then cropping the picture out of the webpage..

1. Replace your current terminal with iTerm.

2. MarsEdit rocks! Ive been posting lazy and all but with this blog client at hand.. blog posting is easier. Way way better compared to ecto!! (IMHO).

Navicat already produced some lite (free) versions for Postgres both for Windows and Mac. Browse over the feature matrix to find out which version works for you. Note that all versions allow you to edit the record which I can’t do in pgadmin3.

A quick look at EMS on Windows (VMWare) is also a note worthy client. Though the MDI interface is a bit complex, one good feature is to able to see your spatial geometry as text and the corresponding SRID immediately…

But right now, I need to tile these images bought from GeoEye, so I need TIFF support. Below is a summary of getting Mapserver installed by source. Note that I have the necessary GEOS, GDAL from kyngchaos as well from this ealier post.

1. Download the ff files:
-rw-r--r--@ 1 rupert  admin   564313 Jul 26 10:32 agg-2.5.tar.gz
-rw-r--r--@ 1 rupert  admin  1345700 Jul 26 10:22 gd-2.0.35.tar.gz
-rw-r--r--@ 1 rupert  admin   613261 Jul 26 10:22 jpegsrc.v6b.tar.gz
-rw-r--r--@ 1 rupert  admin   796551 Jul 26 10:22 libpng-1.2.29.tar.gz
-rw-r--r--@ 1 rupert  admin  1948751 Jul 26 09:55 mapserver-5.2.0.tar.gz
-rw-r--r--@ 1 rupert  admin  1336295 Jul 26 11:11 tiff-3.8.2.tar.gz

2. Install in the ff order:

- jpegsrc
- libpng
- gd (if you have trouble installing gd, then follow this pdf:installing_gd2_on_os_x_server)
- agg (make only)
- tiff
- mapserver

3. For mapserver, please install using the ff configure switches:

./configure \
--with-agg=/myhome/rupert/mapserver/agg-2.5 \
--with-jpeg \
--with-gd \
--with-freetype \
--with-png \
--with-ogr \
--with-proj \
--with-gd \
--with-httpd=/usr/local/apache2/bin/httpd \
--with-tiff \
--with-wfs \
--with-wcs \
--with-sos \
--with-wmsclient \
--with-wfsclient \
--with-tiff \
--with-gdal=/usr/local/bin/gdal/gdal-config \
--with-geos=/usr/local/bin/geos-config \
--with-postgis=/usr/local/pgsql/bin/pg_config

4. Mapserver output

rupert:mapserver-5.2.0 rupert$ ./mapserv -v

1. Download the ff binaries in order (please note the version numbers at the time of writing):

1. UnixImageIO_Framework-1.0.22a.dmg
2. FreeType_Framework-2.3.5-3.dmg
3. GEOS_Framework-3.0.0-2.dmg
4. PROJ_Framework-4.6.0-1.dmg
5. SQLite3_Framework-3.5.7-1.dmg
6. MapServer-5.0.2-2.dmg

2. Once installed, you can copy the mapserv binaries to your apache cgi-bin

sudo cp /Library/WebServer/CGI-Executables/mapserv /usr/local/apache2/cgi-bin/

3. Check the mapserv output

rupert:~ rupert$ /usr/local/apache2/cgi-bin/mapserv -v
MapServer version 5.0.2 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=GEOS INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

This is actually the first time I was able to install mapserver NOT BY SOURCE and still achieve the same binaries that I wanted (with AGG support). Full credit should be given to William.

2. Don’t delete the postgres folder. You might need this later on for future compilations. See pgadmin3 admin pack below.

3. Add a postgres user from System Preferences > Accounts

4. Initialize the data directory

$mkdir /usr/local/pgsql/data
$chown postgres /usr/local/pgsql/data/
$su - postgres
$/usr/local/pgsql/bin/initdb -E utf8 -D /usr/local/pgsql/data

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.
The default text search configuration will be set to "english".

/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data
or
/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start

4. Install Postgis
- install geos with the standard ./configure -> make -> make install
- then install postgis

8.3:
$./configure --with-pgsql=/usr/local/pgsql/bin/pg_config --with-geos=/usr/local/bin/geos-config
 
8.4 using Kyngchaos GEOS Framework:
$./configure --with-pgsql=/usr/local/pgsql/bin/pg_config --with-geosconfig=/Library/Frameworks/GEOS.framework/unix/bin/geos-config
 
$make
$sudo make install

5. Starting postgres on boot. Download postgresstartup.tar.gz then extract to your /Library/StartupItems

6. Creating the database

createdb -E utf8 template_postgis
createlang plpgsql template_postgis
 
8.3:
psql -d template_postgis -f /usr/local/pgsql/share/lwpostgis.sql
psql -d template_postgis -f /usr/local/pgsql/share/spatial_ref_sys.sql
 
8.4:
psql -d template_postgis -f /usr/local/pgsql/share/contrib/postgis.sql 
psql -d template_postgis -f /usr/local/pgsql/share/contrib/spatial_ref_sys.sql

7. Install and download pgAdmin3 for MacOS X

http://www.postgresql.org/ftp/pgadmin3/release/

8. Startup pgadmin3. You will notice there is a window stating…

Server instrumentation
The server lacks instrumentation functions.
pgAdmin III uses some support functions that are not available by default in all PostgreSQL versions. These enable some tasks that make life easier when dealing with log files and configuration files.

9. Compile the adminpack. Go to $postgresql_install_directory/contrib/adminpack

$ make
gcc -no-cpp-precomp -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv  -bundle -multiply_defined suppress  adminpack.o  -L../../src/port -bundle_loader ../../src/backend/postgres  -o libadminpack.0.0.so
rm -f libadminpack.0.so
ln -s libadminpack.0.0.so libadminpack.0.so
rm -f libadminpack.so
ln -s libadminpack.0.0.so libadminpack.so
 
rupert:adminpack rupert$ sudo make install
Password:
mkdir /usr/local/pgsql/share/contrib
/bin/sh ../../config/install-sh -c -m 644 ./uninstall_adminpack.sql '/usr/local/pgsql/share/contrib'
/bin/sh ../../config/install-sh -c -m 644 adminpack.sql '/usr/local/pgsql/share/contrib'
/bin/sh ../../config/install-sh -c -m 755  libadminpack.0.0.so '/usr/local/pgsql/lib/adminpack.so'

10. Load the adminpack.sql into your maintenance and template database

$ psql -U postgres -d postgres -f /usr/local/pgsql/share/contrib/adminpack.sql 
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
...

11. Disconnect and Reconnect from pgAdmin3. You shouldn’t see the window again.

Continue only if you want pgRouting

12. Essentially we would need Boost Graph Library (BGL) a.k.a boost, Genetic Algorithm Utility Library (or, GAUL for short), and GEOS (which we installed earlier when we installed postgis).

13. The easiest way to install boost is using MacPorts.

$ sudo port install boost

Note: I encountered an error when I directly installed “sudo port install boost” on my first run. A quick workaround is to install boost-jam, then install boost afterwards. For more details:

• http://trac.macosforge.org/projects/macports/ticket/13714
• http://trac.macosforge.org/projects/macports/ticket/14043

Error: Target org.macports.build returned: shell command ” cd “/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_boost/work/boost_1_34_1″ && gmake all ” returned error 2 Command output: Makefile:2: *** missing separator. Stop.

14. You can check if boost was successfully installed by…

$ sudo port -v installed boost boost-jam
The following ports are currently installed:
  boost @1.34.1_3+darwin_9 (active)
  boost-jam @3.1.16_0 (active)

15. For GAUL, we don’t need slang base on http://pgrouting.postlbs.org/wiki/1.x/InstallationManual.

$ ./configure --enable-slang=no
$ make
$ make install

16. Ok, so this is the heartbreaker. I was able to get pass cmake on pgRouting on version 1.02 however, I received “undefined symbols” when linking the librouting.dylib

Linking CXX shared library ../../lib/librouting.dylib
Undefined symbols:
  "_errcode", referenced from:
      _shortest_path in dijkstra.o
      _shortest_path_astar in astar.o
      _shortest_path_shooting_star in shooting_star.o

For the complete error details, see pgrouting_problem.txt

17. Thanks to www.kyngchaos.com, we can install http://www.kyngchaos.com/files/software/unixport/pgRouting-1.0.1-4.dmg binary from http://www.kyngchaos.com/wiki/software:postgres

18. Now we can load the pgRouting functions to our template database

psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_core.sql 
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_core_wrappers.sql 
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_dd.sql
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_dd_wrappers.sql 
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_dd_tsp.sql
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_tsp.sql
psql -U postgres -d template_postgis -f /usr/local/pgsql/share/contrib/routing_tsp_wrappers.sql
