undefined reference to a function

[rockymaxdeemann]

HI, ALL
Iam getting a linking error saying "undefined reference to a
function(say fun() ), these are what I've already done :
-- declared fun() as "extern"
-- included the header in all files calling fun()
-- included the header path in the respective "makefiles" calling the
fun()/including the header
file
still Iam getting " ld returned 1 exit status "
Could any one please suggest me where would have I went wrong ??
thnx in advance.

Actually off-topic, since implementation-dependant, but:

-- declared fun() as "extern"
-- included the header in all files calling fun()

file
still Iam getting " ld returned 1 exit status "

You have to feed `ld` /all/ the object files, including the one
for the code for `fun`.

This is a FAQ.
