1   Code to find configuration files in %ETC% : Paul Smedley <paul at smedley.info>

Subject:   Code to find configuration files in %ETC%

Hi All,

I'm having some trouble generating some clean code to make Bind 9.3.2 
find it's configuration files in %ETC% instead of looking in a hardcoded 
directory.

I have some code as per below to grab the ETC directory and append 
named.conf to it:
#ifdef __INNOTEK_LIBC__
const char *env_path; 		(line 83)
env_path=getenv("ETC");
#undef ns_g_conffile
#define ns_g_conffile env_path
#endif

ns_g_conffile is defined to /bind/etc in another file.

The above code works if it is within a function, however if I have it at 
the top of a .c file after all the #includes, etc I get an error like 
the following:
include/named/globals.h:84: warning: type defaults to `int' in 
declaration of `e
nv_path'
include/named/globals.h:84: error: conflicting types for `env_path'
include/named/globals.h:83: error: previous declaration of `env_path'
include/named/globals.h:84: warning: data definition has no type or 
storage clas

Anyone have any ideas why the same code works in a function and not in a 
header?

Cheers,

Paul.
