From 00124713912ead4ce610d519bb3ebab7e31cbea7 Mon Sep 17 00:00:00 2001 From: Vasil Dimov Date: Fri, 5 Jun 2020 11:50:34 +0200 Subject: build: turn on --enable-c++17 by --enable-fuzz Fuzzing code uses C++17 specific code (e.g. std::optional), so it is not possible to compile with --enable-fuzz and without --enable-c++17. Thus, turn on --enable-c++17 whenever --enable-fuzz is used. --- doc/fuzzing.md | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'doc/fuzzing.md') diff --git a/doc/fuzzing.md b/doc/fuzzing.md index 16852bb970..419b1db44e 100644 --- a/doc/fuzzing.md +++ b/doc/fuzzing.md @@ -8,7 +8,7 @@ To quickly get started fuzzing Bitcoin Core using [libFuzzer](https://llvm.org/d $ git clone https://github.com/bitcoin/bitcoin $ cd bitcoin/ $ ./autogen.sh -$ CC=clang CXX=clang++ ./configure --enable-fuzz --with-sanitizers=address,fuzzer,undefined --enable-c++17 +$ CC=clang CXX=clang++ ./configure --enable-fuzz --with-sanitizers=address,fuzzer,undefined # macOS users: If you have problem with this step then make sure to read "macOS hints for # libFuzzer" on https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md#macos-hints-for-libfuzzer $ make @@ -103,7 +103,7 @@ You may also need to take care of giving the correct path for `clang` and Full configure that was tested on macOS Catalina with `brew` installed `llvm`: ```sh -./configure --enable-fuzz --with-sanitizers=fuzzer,address,undefined CC=/usr/local/opt/llvm/bin/clang CXX=/usr/local/opt/llvm/bin/clang++ --disable-asm --enable-c++17 +./configure --enable-fuzz --with-sanitizers=fuzzer,address,undefined CC=/usr/local/opt/llvm/bin/clang CXX=/usr/local/opt/llvm/bin/clang++ --disable-asm ``` Read the [libFuzzer documentation](https://llvm.org/docs/LibFuzzer.html) for more information.
