Hi guys, I'm trying to use modules on my MIPS boards and I'm hitting a snag. # kldload ./wlan.ko # kldload ./ath_hal.ko # kldload ./ath_rate_sample.ko link_elf_obj: symbol ieee80211_iterate_nodes undefined (1) linker_load_file: Unsupported file type kldload: can't load ./ath_rate_sample.ko: Exec format error # nm ./wlan.ko | grep ieee80211_iterate_nodes 00015edc t ieee80211_iterate_nodes # kldstat Id Refs Address Size Name 1 7 0x80000000 80000000 kernel 2 1 0xc7b4e000 538e4 wlan.ko 3 1 0xc7ba2000 70b88 ath_hal.ko # So the wlan module is loaded, it has that symbol internally, but the linker isn't gluing them together. That (1) is a local patch of mine to figure out where it's broken - here, it's broken in link_elf_obj.c:1038 . Ie, it's the first loop in relocate_file(). I'm not up to date on how all this ELF and kernel module/linker magic works, could someone please give me a hand diagnosing why this is happening? Thanks, Adrian
