compilation error

[sam_cit@yahoo.co.in]

Hi All,

I have the following scenario,

A class is declared in the header file and has a static member
function sample() in sample.h
sample.cc uses the static member function sample().

the static member function sample() is under conditional compilation
SAMPLE

ifdef SAMPLE
<classname>.sam ple();
#endif

Now i have set the Macro SAMPLE to false in the Makefile,
SAMPLE=false

and i tried to compile the file sample.cc and it gives an error
saying, static member function() is not defined...
Can anyone help in this regard?

Set the macro SAMPLE to true.

The compilation is fine when the macro is true. I have made sure that
a reference to sample() is always in the conditional compilation
(#ifdef SAMPLE). Hence i would expect the compilation to be fine when
the macro is false.

Also note that when i define the macro SAMPLE to be false in .h
header file, the compilation is fine without error. This makes me
think that there is an issue only when i use the makefile. Please help
me in this regard.

this will always compile as long as SAMPLE is defined, no matter the
value of SAMPLE.

the function call will be included in the translation unit.

probably the definition is not included :)

maybe you are thinking at
#if SAMPLE==false
bla bla bla
#endif
?

Double error?
