[PATCH bpf-next 01/24] selftests/bpf: Fix liburandom_read.so linker error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When building with O=, the following linker error occurs:

    clang: error: no such file or directory: 'liburandom_read.so'

Fix by adding $(OUTPUT) to the linker search path.
