R devel - Jun 2006 - about integration of a library into package creation

hello,

i try to create a package , and i call a library in the namespace file
such as :  useDynLib(quadprog)

after checking my directory with the command "rcmd check" (i am on 
WindowsXP)
i get an error: package / namespace load failed
the path of the library is:     D:\R\library\quadprog
the path of the  building files is:   D:\RBuild\svcR
and the comand i use to compile is:  rcmd check D://RBuild//svcR

i dont understand, it is a path problem about the dll related to the 
library ?

thank for help
Nicolas

You didn't show the results of installing your package.  Did that work?

Generally we advise to do a successful install before you try to run checks.

You shouldn't have .dll files in the R directory.  Normally you have
just one, built in the src directory, and then R will install it into
the libs directory.  If you want multiple .dlls, I believe you can
build them in inst/libs, and they'll be copied to libs on installation.

However, the names of your dlls match the names of R packages, which
makes me think you are trying to incorporate routines from other
packages in your code.  If that's what you are doing, this is not the
right way to do it.  You should call other packages through their R
interfaces.  There are plans to allow direct calls into the dlls, but so
far I don't think they exist.
