Kind regards from Munich. Germany ! Using Gentoo, I tried to follow Jean Delvare's instructions: emerged a fresh clean actual production kernel (gentoo-sources-2.4.25-r2) and renamed the tree to gentoo-sources-2.4.25-r2-sensors - modifying Makefile -> EXTRAVERSION = -gentoo-r2-sensors accordingly. Then I applied the provided patch for 2.4.25. But unfortunately, after quite hopeful compilation efforts, depmod fails: if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.4.25-gentoo-r2-sensors; fi with *** Unresolved symbols in /lib/modules/kernel/drivers/mgavideo/ks0127.o /lib/modules/kernel/drivers/mgavideo/mga_core.o /lib/modules/kernel/drivers/mgavideo/maven.o /lib/modules/kernel/drivers/mgavideo/msp3400.o /lib/modules/kernel/drivers/mgavideo/tuner.o missing i2c_add_adapter i2c_del_adapter i2c_add_driver i2c_del_driver i2c_attach_client i2c_detach_client i2c_get_client i2c_master_send i2c_master_recv i2c_transfer i2c_probe _all_ of these being defined via EXPORT_SYMBOL in linux/drivers/i2c/i2c-core.c But : > grep I2C .config results in : # I2C support CONFIG_I2C=m CONFIG_I2C_ALGOBIT=m # CONFIG_I2C_PHILIPSPAR is not set # CONFIG_I2C_ELV is not set # CONFIG_I2C_VELLEMAN is not set # CONFIG_SCx200_I2C is not set # CONFIG_I2C_ALGOPCF is not set CONFIG_I2C_CHARDEV=m CONFIG_I2C_PROC=m CONFIG_FB_MATROX_I2C=m And: > find /lib/modules/2.4.25-gentoo-r2-sensors/ -name i2c*.o -print results in : /lib/modules/2.4.25-gentoo-r2-sensors/kernel/drivers/i2c/i2c-core.o /lib/modules/2.4.25-gentoo-r2-sensors/kernel/drivers/i2c/i2c-algo-bit.o /lib/modules/2.4.25-gentoo-r2-sensors/kernel/drivers/i2c/i2c-proc.o /lib/modules/2.4.25-gentoo-r2-sensors/kernel/drivers/i2c/i2c-dev.o /lib/modules/2.4.25-gentoo-r2-sensors/kernel/drivers/video/matrox/i2c-matroxfb.o so it seems "i2c-core" _has_ been built. Applying "emerge --ask /usr/portage/sys-apps/lm-sensors/i2c-2.8.4.ebuild" and trying it again led to identical results. ??? Do I have tomatoes on my eyes ??? (Yes, I do realize it's 03:16 early in the morning over here ;-) ??? Can you help me and spot it ??? Greetings and thanks in advance - Manfred
