ERROR: sys-apps/tpctl-4.4-r1 failed. !!! Function src_compile, Line 32, Exitcode 2 !!! tpctlir make failed This is on a Thinkpad 760EL. so I really need tpctlir. without USE="tpctlir" it compiles fine. if you need additional info: #gentoo: roger55 Reproducible: Always Steps to Reproduce: 1. 2. 3.
This looks you are compiling an SMP module for a non-SMP kernel. In asm.system.h: #ifdef CONFIG_SMP extern void __global_cli(void); extern void __global_sti(void); extern unsigned long __global_save_flags(void); extern void __global_restore_flags(unsigned long); #define cli() __global_cli() #define sti() __global_sti() #define save_flags(x) ((x)=__global_save_flags()) #define restore_flags(x) __global_restore_flags(x)
Added a patch that makes it compile regardless of CONFIG_SMP setting, but I'm not certain it works perfectly anymore. (According to the Linux IO Programming Mini-HOWTO, my new approach is how to do it, but it's probably outdated....)
fix works fine. emerged and works fine. thanks a lot! roger55
