Porting (computer science)
I will discuss here some thoughs about some porting issues and hidden problem, I hope to give 3 years in experience in this field.
first take a look on porting in wikipedia here.
First hoax is, C is not a portable lanaguage ,this is due to vast amount of compiler and each compiler works as a compiler to it own C language.and most Legacy code is written with no regard to ANSI standard.
Most common C compilers
My job was to port some application created by IBM Called CT (Consumer Transaction) -which is used in banking system- from windows to linux.
Other thing that make this task very difficult that there are not formal design of code was not available. and we have to figure it out.
the code was about 1.5 MB (plain text code size) and it was first write for OS/2 platform and then ported to Windows and our task is to first port it to linux then makes some modifications and additions to it.
Bye for now

- GCC (I recommend it to much)
- Microsft Compiler
- VisualAge Compiler
