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
