undefined reference to `cpuinfo_loongarch_linux_init'

[manhongnie]

My pytorch version is 1.8 My computer is a loongarch, I want to adapt the cpuinfo library to my computer, so I added cpu_loongarch_linux_init according to the function cpuinfo_arm_linux_init, all the definitions are the same, why still report an error, the following is a hint ""/Usr/bin/ld: ../lib/libcpuinfo.a(init.c.o): in function cpuinfo_initialize': (.text+0x4): undefined reference to cpuinfo_loongarch_linux_init' /usr/bin/ld: (.text+0x8): undefined reference to cpuinfo_loongarch_linux_init' /usr/bin/ld: (.text+0x8): undefined reference to cpuinfo_loongarch_linux_init' /usr/bin/ld: ../lib/libtorch_cpu.so: hidden symbol `cpuinfo_loongarch_linux_init' isn't defined"
