Dear all, I'm trying to build xenomai-2.6.0 with kernel 3.0.4 for powerpc (MPC5121). some config options: CONFIG_PPC_MPC512x=y CONFIG_XENO_DRIVERS_CAN=m CONFIG_XENO_DRIVERS_CAN_MSCAN=m Using CAN support leads to compile errors: CC [M] drivers/xenomai/can/mscan/rtcan_mscan.o CC [M] drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.o drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.c: In function 'mpc512x_can_get_clock': drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.c:158:30: error: 'struct platform_device' has no member named 'node' drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.c:174:41: error: 'struct platform_device' has no member named 'node' drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.c:178:31: error: 'struct platform_device' has no member named 'node' make[5]: *** [drivers/xenomai/can/mscan/rtcan_mscan_mpc5xxx.o] Error 1 I'm a bit surprised as I found a xenomai git commit that seem to handle this issue when building with CONFIG_PPC_MPC52xx: - can: adapt to platform driver infrastructure changes for 2 .6.35 http://git.xenomai.org/?p=xenomai-head.git;a=commit;h=50b289784ef2b0734bef1e99b008ff4b79ad5409 I believe this issue can be fixed for MPC512x as well, by using same principle. Is it correct to do so?
