Hey Everyone, I'm running R 2.4.0 on Debian etch 4.0, and I'm trying to call some Lapack functions from my C code. Actually, to be honest I'm not really having trouble calling the commands such as La_dgesv from within my C code, but I do get warning when compiling the package saying: GAUSSlkhd.c: In function 'GAUSSlkhd': GAUSSlkhd.c:37: warning: implicit declaration of function 'La_dgesv' GAUSSlkhd.c:37: warning: assignment makes pointer from integer without a cast I tried using: #include <Rmodules/Rlapack.h> but it won't compile the package at all with that included, complaining that bjl.h:5:30: error: Rmodules/Rlapack.h: No such file or directory Can someone explain to me how I should include the AWESOME wrapper code to the Lapack libraries? Am I not following the proper protocol by using these La_* commands in my package source code? TIA, Brian
