| Frequently Asked Module User Questions |
| |
| Q) I get "/usr/bin/ld: cannot find -lc" |
| A) You need to install a development package which contains libc.a. |
| |
| Q) I'm using RedHat and modules don't autoload any more. |
| A) Old versions of RedHat turns module autoloading off if /proc/ksyms |
| isn't found. Change line 337 of /etc/rc.d/rc.sysinit from: |
| |
| if ! grep -iq nomodules /proc/cmdline 2>/dev/null && [ -f /proc/ksyms ]; then |
| |
| to |
| |
| if ! grep -iq nomodules /proc/cmdline 2>/dev/null && [ -f /proc/modules ]; then |
| |
| Q) Things still don't load properly. |
| A) Do you have an /etc/modprobe.conf? If not, use |
| generate-modprobe.conf to generate an /etc/modprobe.conf from your |
| old setup. |
| |
| Q) Sound doesn't load automatically. |
| A) You need to set up an alias (or install command) for "sound-slot-0" in |
| /etc/modprobe.conf: the ALSA sound system seems to want this. |
| |
| Q) What is "[unsafe]" next to the module name in lsmod? |
| A) It means somone used an old-style interfaces to try to control this |
| module: these are slowly being tracked down and eliminated. You can |
| use "rmmod -f" to force removal if you configured your kernel with |
| CONFIG_MODULE_FORCE_UNLOAD set. |
| |
| Q) I'm having trouble inserting out-of-tree modules |
| A) See kernel source tree documentation: Documentation/kbuild/modules.txt |
