Compile PHP with unixODBC options

I have XAMPP 1.7 running, with php 5.2.8. Old yes but almost all of my running projects are
built on top of it. Recently i got a project that requires to use MSSQL-SQLEXPRESS.
I chose to use Codeigniter 2.1.2 as the framework to develop. One of teammate is using
MS-Windows environment and he used sqldrv as the database driver with ease.

While my part using GNU/linux Fedora19 64bit having problem. After while searching how to
connect to SQLExpress than the easy answer itu to use FreeTDS and unixODBC. Modify
php.ini of XAMPP 1.7 with no problem. After restart apache and run one of my test_odbc
file shows an error "undefined reference odbc_connect()"

More googling and ends up that i convincing my-self to compile the odbc library from scratch.
So i yum install  unixODBC-devel.i686 and so freetds-devel.i686 then download php 5.2.8
source file from Here. Done the extraction, now to build the extention.

$ pwd
$ /opt/lampp/bin/phpize

$ sudo yum install glibc-devel.i686
You need the glibc-devel so you can build 32bit application on 64bit system
$ ./configure --with-php-config=/opt/lampp/bin/php-config --with-unixODBC=shared,/usr CFLAGS='-m32'
Then Error that saying
checking for Adabas support... cp: cannot stat '/usr/local/lib/odbclib.a': No such file or directory
configure: error: ODBC header file '/usr/local/incl/sqlext.h' not found!

You could solve this by modifying Makefile that being generated, goto line 4737 and removed
  ext_output="yes, shared"
  test "$PHP_ADABAS" = "no" && PHP_ADABAS=yes
I don't know what caused the double occurrences that simply override the previous check
and initialization. Re-run the configure

compilation terminated.
make: *** [php_odbc.lo] Error 1

Well at this point is strange if you open the php_odbc_includes.h:74 it says HAVE_ADABAS 
blabla, i just removed all off them until it reaches the #elif ... HAVE_UNIXODBC

$ make 
And success it says
Build complete.
Don't forget to run 'make test'.
At this point if you check the modules/ you will see sits there, yeah!
I like the manual-way so i just copy and paste on my XAMPP extention folder.

Restart the Apache service and run my script yeah! Now it connects like charm :))

Compiling Antlr2

Compiling Antlr2 with no success. As of this article being written the latest version is 2.7.7.
The source is downloaded and configured but when `make` processing this errors comes in.

Includes some headers fixed the problems. Open the CharScanner.cpp and put this at the header.

#include   >fstream<
#include   >strings.h< // before
#include   >antlr/config.hpp<
// and

#include >antlr/exersharedinputstate.hpp< // after
#ifndef EOF
    #define EOF     std::ifstream::traits_type::eof()

Run `make clean` and the `make; make install`. Compile success, Yeah!

Compile C++ BOOST Example

Playing around with Boost 1.58 library, i need to experience the compile and run the examples.
I go into libs/serialization/examples/ run b2 hummm seems to build everything. So give it a try
to compile it "by-hands"

$ pwd


$ export LD_LIBRARY_PATH=/opt/c++/boost_1_58_0/stage/lib:$LD_LIBRARY_PATH

$ c++ demo.cpp -o demo -L /opt/c++/boost_1_58_0/stage/lib -lboost_serialization-mt

$ ./demo

** Throws some log meaning the application compiled and run successfully
