Hi guys, Recently, I'm trying to apply KLEE to busybox1.21.0. I followed the
subsequent steps:mkdir obj-klee
make -w O=obj-klee defconfig
cd obj-klee
make CC=klee-gcc LD="llvm-ld --disable-opt" AR=llvm-ar SKIP_STRIP=y V=1
make CC=/home/wang/work/klee/scripts/klee-gcc LD="llvm-ld --disable-opt"
SKIP_STRIP=y V=1 AR=llvm-ar CFLAGS=-fnested-functions
But,an error happened:------------------------
-------------------------

Trying libraries: m

llvm-ld: error: Cannot find linker input 'selinux/lib.a'
make[2]: *** [busybox_unstripped] Error 1
make[1]: *** [_all] Error 2
make: *** [all] Error 2
When I check selinux/lib.a, the file is there, but it contains only a single
line with: "!<arch>" . Someone can help me ? If any, could you tell me how to
solve it? I'm really hurried with this test. Thank you very much for advance!
