I need to compile libav library with AFLGO.
cd ~export AFLGO=$PWD/aflgocd path/to/libav/folderexport SUBJECT=$PWD; export TMP_DIR=$PWD/obj-aflgo/tempexport CC=$AFLGO/afl-clang-fastexport CXX=$AFLGO/afl-clang-fast++export COPY_CFLAGS=$CFLAGSexport COPY_CXXFLAGS=$CXXFLAGSexport ADDITIONAL="-targets=$TMP_DIR/BBtargets.txt -outdir=$TMP_DIR -flto -fuse-ld=gold -Wl,-plugin-opt=save-temps"export CFLAGS="$CFLAGS $ADDITIONAL"export CXXFLAGS="$CXXFLAGS $ADDITIONAL"export LDFLAGS=-lpthread./configureit returns:
gcc is unable to create an executable file.If gcc is a cross-compiler, use the --enable-cross-compile option.Only do this if you know what cross compiling means.C compiler test failed.If you think configure made a mistake, make sure you are using the latestversion from Git. If the latest version fails, report the problem to thelibav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.Include the log file "avbuild/config.log" produced by configure as this will helpsolving the problem.I have checked config.log but it doesn't seem useful, these are the last lines:
....gcc -targets=/home/ubuntu16/Documents/github-repos/libav/obj-aflgo/temp/BBtargets.txt -outdir=/home/ubuntu16/Documents/$gcc: error: unrecognized command line option '-targets=/home/ubuntu16/Documents/github-repos/libav/obj-aflgo/temp/BBtar$C compiler test failed.why does this try compile it with gcc again? I want to instrument it with AFLGo fuzzer.
