Why GCC Compiler is not support for different versions .....

[John (Eljay) Love-Jensen]

Hi Karthik,

> My question is, why the application is not supported in higher version of gcc
4.3 

I do not know the particular problem your application is running into.

Here are some of the reasons I have experienced for why applications which
used to work with older versions of GCC do not work with later versions of
GCC:

+ Old application relied on C++ non-compliant feature of (older) GCC¹s C++,
and now GCC is C++ compliant on that issue

+ Old application was written in pre-1998 C++ (before ISO 14882 standard),
and is not ISO 14882 C++ compliant

+ Old application has inline assembly, and is now being compiled on a
different platform.

+ Old application was has platform specific APIs, and is now being compiled
on a different platform.

+ Old application relied on GCC extensions, and those extensions have since
been deprecated and then removed (I used to rely on GCC extensions...
ummm... extensively; now I'm an ISO 14882 stickler)

> what is reason for that and how it can be solve

Almost always, the way it can be solved is to fix your application¹s source
code.
