Mac OSX: Leopard to Snow Leopard Upgrade

Snow Leopard Installer DVD was delivered in our office on Saturday and I couldn’t wait to upgrade to Snow Leopard (10.6.x). I could have upgraded earlier, if Apple had enough stores and better reseller network in India.

Anyway, upgrade was smoother  compared with Tiger(10.4.x) to Leopard (10.5.x) upgrade. Installer UI has around 4-5 steps and none of steps mention “upgrade” word. Installer is smart enough to detect existing installations, figure out which printer drivers to keep or install. However, it chooses all languages (translation) to install even when you didn’t have those in Leopard.

Within fourty mintues, upgrade was completed and I was back in action.

However, In my case, I have to spend some more time to setup/fix things which were broken, such as:-

  1. Reinstalled MacPort using installer for snow-leopard and upgraded some of packages (libiconv, jpeg, libpng, libmycrypt, openssl, gettext, freetype, openssl, curl) and their dependencies for 64bit compatibilities (+universal, +variants)
  2. Compiled Apache, MySQL and PHP for 64 bit
  3. Reinstalled Remote Desktop Connection using latest installer to fix crash issue on Snow Leopard

If you don’t want to use MacPorts, you can download source of these libraries separately, compile and install. These would be installed in /usr/local unless you change the prefix.

Installing 64 bit version of Apache, MySQL and PHP took around two-three hours because of some issues related to libiconv.2.dylib. Apache would compile but fail to run, reporting incorrect version of libiconv. I downloaded libiconv source, compiled and installed it in /usr/lib (instead of /usr/local/lib). Apache started working but  vim, make, other unix programs (chmod, etc) failed to run using latest libiconv.2.dylib.

I tweaked the setting in /usr/sbin/envvars to use following:-

DYLD_LIBRARY_PATH="/usr/lib:$DYLD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH
export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/lib:/opt/local/lib:/sw/lib

Basically, added a fallback path so if library is not found in /usr/lib, it would look into other directors, as specified.  After doing this, Apache (64bit) and vim, make, chmod, etc started working.

MySQL compilation was straight forward with following command, thanks to this link, I just added CFLAGS=”-arch x86_64″  while compiling to make sure mysql is compiled for 64 bit. Moved data directory back to new mysql installation directory.

Compiling php 5.2.13 resulted into some errors related to iconv, hash and gd. After spending sometime, I decided to compile without these extensions with following commands:

MACOSX_DEPLOYMENT_TARGET=10.6
CFLAGS="-arch x86_64 -g -Os -pipe -no-cpp-precomp"
CCFLAGS="-arch x86_64 -g -Os -pipe"
CXXFLAGS="-arch x86_64 -g -Os -pipe"
LDFLAGS="-arch x86_64 -bind_at_load"
export CFLAGS CXXFLAGS LDFLAGS CCFLAGS MACOSX_DEPLOYMENT_TARGET
./configure --prefix=/usr/local/php5 --exec-prefix=/usr/local/php5 --disable-dependency-tracking --sysconfdir=/private/etc --with-apxs2=/usr/sbin/apxs --enable-cli --with-config-file-path=/etc --with-libxml-dir=/usr --with-openssl=/usr --with-kerberos=/usr --with-zlib=/usr --enable-bcmath --with-bz2=/usr --enable-calendar --with-curl=/usr --enable-exif --enable-ftp --without-gd --with-jpeg-dir=/opt/local/lib --with-png-dir=/usr/local/lib --with-freetype-dir=/usr/X11R6 --with-xpm-dir=/usr/X11R6 --with-ldap=/usr --with-ldap-sasl=/usr --enable-mbstring --enable-mbregex --with-mysql=mysqlnd --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-iodbc=/usr --enable-shmop --with-snmp=/usr --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --without-xmlrpc --without-iconv --with-xsl=/usr

#if everything goes well
make

#if everything goes above, install php5 in /usr/local/php5
sudo make install

I checked (php -m) some extensions (xdebug, etc) were not loading, so I updated those individually, specially iconv, xmlrpc and gd. Compiling an extension is generally four step process. For example, if you want to compile iconv, you can do the following:

$ cd /php-source/ext/iconv
$ phpize
$ ./configure --with-iconv=/usr
$ make
$ sudo make install

It all worked fine, apache was loading php fine and all my websites and applications work fine.

BSNL 3G configuration – new access point name

It seems BSNL secretly changed the 3G access-point details around couple of weeks back, so my 3g connection stopped working. I looked over internet to figure out the latest configuration details, I couldn’t locate one.

I talked to BSNL 3G technical guys in Kanpur and to my surprise, most of them were also not aware of the change. Thankfully, one of the guys from BSNL Bangalore office, confirmed the latest access-point details, as shown below:

Access point name: gprsnorth.cellone.in bsnlnet

In case you are wondering, what all other changed, that’s it. JFYI! Old access-point name was gprsnorth3g.bsnlmobile.in, which doesn’t work anymore.

So if you have been unable to use BSNL 3G during last couple of weeks, perhaps new access-point name can work for you.

I am not sure, if there are different access-point name for different parts of country (north, south, east, west)?
