about R CMD check

From: xt_wang at cse.concordia.ca

hello, everybody,

I create a package by myself named "var" on Linux system. I 
attach a C code
which uses "R_ext/Lapack.h" in directory "src". But when I 
carry out " R CMD
check var", it shows

 wxt0124()

Error in .C("wxt1221", PACKAGE = "var") : C function name not 
in DLL for package
var
Execution halted

Could you tell me what is the problem?

Maggie
