Solaris

Dear Experts,
i am very new to Sun Solaris, when i tried to compile some source file,
i see even though they are defined in the header files they were showing not defined because they were written
what do these extensions indicate how to to handle them

and also i saw one of the .exe when i tried to check its type it is showing

what do these indicate please explain me as i searched in the net i did not get anything.

How can you execute .exe file in a Sparc machine?

When it isn't an exe! I've seen file.bat scripts...

The output from the file(1) command pointed at a file is of course looking at the contents of the file not its name.

It is in the script i am giving name like that , u can assume a .so which describes me like that

Code:

user.so: ELF 64-bit MSB executable SPARCV9 Version 1, UltraSPARC1 Extensions Required, dynamically linked, not stripped

please tell me in all most all header files i have seen

Code:

if(__EXTENSIONS__)
or 
if(__STDC__)

what do these indicates please explain these are i think some basics of sun solaris as i am new to it i am not getting please tell me what do __EXTENSIONS__ indicate.

These macros are set depending on the source code standard conformance level requirements.

__STDC__ means strictly conformance to ISO C without K&R C compatibility extensions while __EXTENSIONS__ means various non conflicting extensions are allowed.

Thanks for your reply,

if my code is in POSIX standards, then while compiling i am setting the
-D_POSIX_C_SOURCE=199506L , so what is the impact of this on those macros please if there is any documentation which describes in detailed about the macros of SUN please refer there __EXTENSIONS__ what do various extensions refer to.

What C compiler are you using ?
