unresolved symbols in dynamically linked code
...ably misunderstanding something in "Writing R Extensions" version
1.0.0. In the chapter on the R API, section 4.7, it is stated that the
functions listed in R_ext/Linpack.h are available to users' Fortran code.
I am developing a developing a library of ode solvers, based on lsoda and
ddassl, and which in turn call some routines from linpack and double
precision blas. I originally developed the library including those
routines, and got a functional shared library. When I removed the
routines listed in Linpack.h, dyn.load gave the error:
...../call_lsoda.so: undefined symbol dgbfa_...

Ordinary differential equations in R?
Is there any R code available for solving ODE's? I am considering building
an interface to ODEPACK, but don't want to duplicate any existing effort.
