hi there!! I installed and compiled kernel version 2.4.17 and I tried to install the 'lm sensors' to monitor the CPU temperature. But I got: gcc -o prog/sensors/sensors prog/sensors/main.ro prog/sensors/chips.ro -Llib -lsensors lib/libsensors.so: undefined reference to `sensors_yylex' lib/libsensors.so: undefined reference to `sensors_yyin' lib/libsensors.so: undefined reference to `sensors_lex_error' lib/libsensors.so: undefined reference to `sensors_yylineno' collect2: ld returned 1 exit status I'm using the RedHat 7.2 Linux with 2.4.17 kernel compiled from the source package from www.kernel.org. Is there any way to compile and install lm sensors? Krzysztof (Christopher) ----------------------------- Krzysztof Mazurek System Administrator Krzysztof.Mazurek at expander.pl (+48)608-555-392
