32 bit compilation #85

Open GrosQuildu opened 4 years ago

GrosQuildu commented 4 years ago

Good morning,

Does Angora support 32-bit targets / builds?

Like:

CC=$ANGORA/bin/angora-clang ./configure --prefix=`pwd`/install --disable-shared "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"

, which fails in my environment, because Angora libs are 64bits:

/usr/bin/ld: ./Angora/bin/lib/libruntime_fast.a(runtime_fast-d39a4de5e860747f.runtime_fast.9lmpyn81-cgu.11.rcgu.o): file class ELFCLASS64 incompatible with ELFCLASS32

Also can't build 32-bit version of Angora with:

cargo build --target=i686-unknown-linux-gnu
cargo build --release --target=i686-unknown-linux-gnu

because the build fails at https://github.com/AngoraFuzzer/Angora/blob/cd5439f383582b30c93def0f712a05ab9284ec25/fuzzer/src/executor/limit.rs#L23 with "expected u32, found u64".

Any option to do that?

Sorry, Angora doesn't support 32bit now. I will improve it in my plan. Thanks for your suggestion.
