Hi Woodrow, Peter and others. Getting rid of those excess files smoothed the process a little:
Rcmd SHLIB mymod.c C:\Program Files\R\R-2.7.2\library\odesolve\dynload\c>Rcmd SHLIB mymod.c gcc -std=gnu99 -IC:/PROGRA~1/R/R-27~1.2/include -O3 -Wall -c mymod.c -o mymod.o gcc -std=gnu99 -shared -s -o mymod.dll mymod.def mymod.o mymod_res.o -LC:/PROGRA~1/R/R-27~1.2/bin -lR This completed without returning an error. The problem now is that it did not produce a "mymod.so" in the folder, only a mymod.o. so the dyn.load() command in the example R program has nothing to work with.. Any ideas?

In the ...odesolve/dynload/c directory of the windows distribution are two files that should not be: mymod.o and mymod.so (I just noticed them). Try deleting them and rerunning your compilation. By the way, you might want to take a look at deSolve, which supercedes odesolve. deSolve includes lsoda with the same API as in odesolve, but also includes several other ode solvers you might find useful. In the next several months, odesolve will be deprecated. R. Woodrow Setzer, Ph. D.

Any chance that you have old versions lying around? -- O__ ---- Peter Dalgaard Øster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.
