...I could ever write myself. After some twiddling I have got my code to compile by including "R_ext/Lapack.h" and using "F77_CALL(dpotrf)", but unfortunately, I don't get this to link properly. I get this message: " testc.o:testc.c:(.text+0x255): undefined reference to `dpotrf_'" which seems logical to me as far as my understanding of C reaches, but I don't know how to resolve it. I'm quite sure I need some extra parameters in my makefile, but as I come from a world where all these complexities are happily abstracted away for me by an IDE, I have no actua...

...TRF. I can see the source code and check that my call is correct, but it does not compile with: system("R CMD SHLIB ~/main.f") dyn.load("~/main.so") I get: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library [...] undefined symbol: dpotrf_ Could anyone point out how to compile with such a call to lapack? 2) Calling the Fortran function CHOL The previous combination of R CMD SHLIB and dyn.load compiles fine but I would like to see the source code of this function to check if my call is correct. I've not been able to find it...

...-L/usr/local/lib -o testmore.so testmore.o However, I get the following error in R: > dyn.load("testmore.so") Error in dyn.load("testmore.so") : unable to load shared library '/home/mhitczen/Cstuff/testmore.so': /home/mhitczen/Cstuff/testmore.so: undefined symbol: dpotrf_ This error goes away and everything works when I simply call the BLAS routine (In the testmore.c file I simply remove funct2, leaving funct which calls the routine "dgemm" found in the BLAS.h file). I read the "Writing R Extensions" and created a file: /R-2.9.0/src/Makevars th...
