Hi all, I'm trying to insert a module into the kernel (2.6.35.5). There are no errors during the "make" phase. There are only warnings regarding two symbols : WARNING: "__udivdi3" [/media/Study/project_work/splitting_merging/radc_try1/radc1.ko] undefined! WARNING: "__umoddi3" [/media/Study/project_work/splitting_merging/radc_try1/radc1.ko] undefined! But during the "insmod" step, the module is not getting inserted into the kernel saying that there is an undefined symbol in the .ko file of the module. dmesg O/P : adc1: Unknown symbol __fixsfsi (err 0) radc1: Unknown symbol __umoddi3 (err 0) radc1: Unknown symbol __udivdi3 (err 0) radc1: Unknown symbol __floatundisf (err 0) radc1: Unknown symbol __umoddi3 (err 0) radc1: Unknown symbol __udivdi3 (err 0) If anyone can help me with tackling these errors, it would be really helpful...... Regards, Gaurav
