You can pass --enable-debug to the configure script in order to enable debug symbols (and don't strip programs/libs). For the kernel and modules, define CONFIG_XENO_OPT_DEBUG and CONFIG_DEBUG_KERNEL/CONFIG_DEBUG_INFO to have symbols and all. OProfile is only able to look up virtual address when debug symbols are present in file. You may have to pass the --vmlinux option to opcontrol. Compiling Xenomai like suggested by Jan will make your life easier, and will bring you an extra mini speedup if you're in that kind of business. -- Stephane _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
