C Language: Dependency error while compiling

Question

Am facing a problem in resolving dependencies in C,

config.h file is as follows,

...
....
/* MACRO */
/* #undef MACRO */
....
....

And a file example.c contains,

...
     #ifdef MACRO 
     #include "../../sample_header.h"
     #endif
...

while resolving dependencies, the compiler is trying to resolve the sample_header.h file even though the "MACRO" is not enabled. Its very weird. Could anyone help on this issue.

Answer 1

The issue is resolved. The problem i forgot to do "autoreconf" after making changes in configure.ac file. So whenever any change is done in configure.ac "autoreconf" has to be done.
