Dynamically creating structure in C/C++ program

Hi,

For one of the project which i am working on i need to write a cpp code such that it will create the structure dynamically instead of reading it from header file.

For example we have a program which is reading a binary file according to the structure mentioned in header file.

But we want to make the program to generic to support reading of binary file of any structure that we pass to it through a config file.

Can you suggest how we can do this ?

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
