Hello, i'm trying ls_sensors to watch our Webserver. i2c compiles fine. At the compile time for lm_sensors i got this: gcc -D__KERNEL__ -DMODULE -DEXPORT_SYMTAB -fomit-frame-pointer -I. -Ikernel/include -I/usr/local/include -I/usr/src/linux/include -O2 -c kernel/chips/lm92.c -o kernel/chips/lm92.o kernel/chips/lm92.c:96: warning: parameter names (without types) in function declaration kernel/chips/lm92.c: In function `lm92_temp': kernel/chips/lm92.c:180: `mutex' undeclared (first use in this function) kernel/chips/lm92.c:180: (Each undeclared identifier is reported only once kernel/chips/lm92.c:180: for each function it appears in.) kernel/chips/lm92.c: In function `lm92_alarms': kernel/chips/lm92.c:207: `mutex' undeclared (first use in this function) kernel/chips/lm92.c: In function `lm92_detect': kernel/chips/lm92.c:280: `mutex' undeclared (first use in this function) kernel/chips/lm92.c:298: `THIS_MODULE' undeclared (first use in this function) kernel/chips/lm92.c: At top level: kernel/chips/lm92.c:415: warning: parameter names (without types) in function declaration kernel/chips/lm92.c:415: warning: data definition has no type or storage class kernel/chips/lm92.c:416: warning: parameter names (without types) in function declaration kernel/chips/lm92.c:416: warning: data definition has no type or storage class make: *** [kernel/chips/lm92.o] Error 1 Whats this mean??
