Re: [Rd] odesolve dynload example
Hi Matthew,
thank you for the bug report, Woodrow Setzer just uploaded a minor
bugfix and I assume he informed you off-list.
One additional note for the records:
We suggest odesolve users should switch over to the new deSolve package.
It is maintained by the the same (and two additional) authors like
odesolve. It is almost ;-) fully compatible to odesolve and will replace
it completely. The authors renamed it to deSolve, because it's able to
solve also DAE and PDE systems, not only ODEs, so the name odesolve was
too narrow and is now deprecated.
Note that deSolve has a package vignette about writing models in
compiled code.

I had a look at the archives and did not find anything on this, so hopefully I am not doubling up. I have tried to use R cmd to create an object file from the odesolve dynload example. I am using windows and have just installed rtools, and have the latest version of stable R (2..7.2). This is what happened: C:\Program Files\R\R-2.7.2\library\odesolve\dynload\cRcmd SHLIB mymod.c making mymod.d from mymod.c windres --preprocessor=gcc -E -xc -DRC_INVOKED -I C:/PROGRA~1/R/R-27~1.2/include -i mymod_res.rc -o mymod_res.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 Cannot export myderivs: symbol not found Cannot export myjac: symbol not found Cannot export mymod: symbol not found mymod.o: In function `mymod': /home/setzer/tasks/Programming_Projects/odesolve/odesolve/inst/dynload /c /mymod.c:14: undefined reference to `GLOBAL_OFFSET_TA BLE_' mymod.o: In function `myderivs': /home/setzer/tasks/Programming_Projects/odesolve/odesolve/inst/dynload /c /mymod.c:21: undefined reference to `GLOBAL_OFFSET_TA BLE_' mymod.o: In function `myjac': /home/setzer/tasks/Programming_Projects/odesolve/odesolve/inst/dynload /c /mymod.c:30: undefined reference to `GLOBAL_OFFSET_TA BLE_' collect2: ld returned 1 exit status make: *** [mymod.dll] Error 1 Any ideas what I have not got set up properly? What do I need to do to get this firing? Advice appreciated. I'm a bit rusty on the windows tools, but it looks like mymod.o and mymod_res.rc not being made above. Any chance that you have old versions lying around? -- O__
