Hello Chris, I have tried compiling the app with -lm flag but to no avail. I think the rtems-libbsd waf build process has to be modified a bit to link sfp.c using the -lm flag. I tried altering the libbsd waf script but couldn't fix the error. I'm trying to fix it and any help is greatly appreciated. :)
