ERROR in step 7 while running "./autogen.sh" about aflgo HOT 14 CLOSED

sudo sh ./autogen.sh

I tried this way and seems solve the problem.But I found if use "sudo", the default gcc will be applied instead of afl-clang-fast, and finally get an uninstrumented target.
I read the config.log, and found out the problem maybe an error in "afl-clang-fast --version". I tried this command outside and it causes an endless loop. I restart my terminal , set the environment variables , and execute the command again.It works, and the autogen.sh works as well.

Can you successfully build libxml2 standalone?

Hi, mboehme.
I skipped

export CC=$AFLGO/afl-clang-fast
export CXX=$AFLGO/afl-clang-fast++

and still failed with the same error.
But I found that skipping both
export CC=$AFLGO/afl-clang-fast export CXX=$AFLGO/afl-clang-fast++
and
export ADDITIONAL="-targets=$TMP_DIR/BBtargets.txt -outdir=$TMP_DIR -flto -fuse-ld=gold -Wl,-plugin-opt=save-temps"
will succeed building.

Is the problem lying in the parameter "-targets"?
Looking forward to your reply.

What does config.log say (last few entries)?

from aflgo.

configure:3593: checking whether the C compiler works
configure:3615: gcc -targets=/BBtargets.txt -outdir= -flto -fuse-ld=gold -Wl,-plugin-opt=save-temps conftest.c >&5
gcc: error: unrecognized command line option '-targets=/BBtargets.txt'

Firstly, it seems your TMP_DIR variable is not set (See step 5)

Secondly, it configures with GCC as compiler. Please run

export CC=$AFLGO/afl-clang-fast
export CXX=$AFLGO/afl-clang-fast++

and see what config.log says.

Hi mboehme,
I solved the building problem by rebuilding the LLVM-gold plugin.
Now I passed building libxml2 but got stuck in generating distance, that is
$AFLGO/scripts/genDistance.sh $SUBJECT $TMP_DIR xmllint.
I got the following error：
Couldn't find any binaries in folder /home/chenyixiu/libxml2.
Thanks for your reply.

from aflgo.

Can you locate xmllint? Is it in /home/chenyixiu/libxml2?

from aflgo.

chenyixiu@chenyixiu-INVALID:~$ locate xmllint
/home/chenyixiu/libxml2/xmllint

Another possible way to solve that issue is to ensure that you set AFL_CC and AFL_CXX and point them to the clang you want.

try

 sudo sh ./autogen.sh

it worked for me

from aflgo.

Hello. I have a same problem "Couldn;t find any binaries in folder /home/yjgo/libxml2".
And I compiled the libxml2 with afl-clang-fast but I don't have any bc files.
Could you give me any suggestion?
It would be very helpful to me.
Thanks

endless loop
could more clearly introduction how to success

Did sudo sh ./autogen.sh resolve your problem? If so, we could add it to the tutorial.
