Hi and Merry Xmas tomorrow, Running SuSE Linux 8.0 with a Pentium 4 1.4GB on an Intel board with scsi drives kernel appears to be /lib/modules/2.4.18-64GB-SMP home/stan/Documents/i2c-2.7.0/make OK. home/stan/Documents/i2c-2.7.0/make install fell foul of permissions and could not mkdir 'misc' su to root and make install and depmod -a both completed without complaint home/stan/Documents/lm-sensors_2.7.0/make required install of 'bison' and 'flex' and then pulled up with:- 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 Make: *** [prog/sensors/sensors ] Error 1 su to root gave the same result. Following from your FAQ, prog/detect/i2cdetect and prog/detect/sensors-detect both return 'No such file or directory" What do I need and where is it hidden ? Stan
