[llvm-dev] llvm-dev Digest, Vol 179, Issue 18
Hello, I have a question now, according to the official llvm documentation, if you want to build fuzzers, you need to add following compile options as shown below.>>>-DLLVM_USE_SANITIZER=Address -DLLVM_USE_SANITIZE_COVERAGE=On >>>-DLLVM_BUILD_RUNTIME=OffUse the following cmake command "cmake -G 'Unix Makefiles' -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_SANITIZER=Address -DLLVM_USE_SANITIZE_COVERAGE=On -DLLVM_BUILD_RUNTIME=Off -DLLVM_TARGET_TO_BUILD=X86 ../LLVM-8.0.0" but when you make. you will be prompted the following error message:>>>"c++: error: unrecognized argument to -fsanitize= option: 'fuzzer-no-link'.This is because the c++ do not have no value named 'fuzzer-no-link'. So i want to know what cmake command should I use to build a compiler that can use the fuzzer tools. In addition, I am a person who has just joined the community. How can I find the solution to my problem？Please let me know, thanks you. Best wishes. ---------------------------------------------------------------------- On 05/06/2019 01:19, via llvm-dev wrote: Send llvm-dev mailing list submissions to llvm-dev at lists.llvm.org To subscribe or unsubscribe via the World Wide Web, visit https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev or, via email, send a message with subject or body 'help' to llvm-dev-request at lists.llvm.org You can reach the person managing the list at llvm-dev-owner at lists.llvm.org When replying, please edit your Subject line so it is more specific than "Re: Contents of llvm-dev digest..."

According to the official llvm documentation, the fuzzer tool will automatically link to Libfuzzer, but when I use it, I will prompt the following message "This tool was not linked to libFuzzer". When building the compiler, I used the following cmake command, "cmake -G "Unix Makefiles" -DLLVM_BUILD_TYPE=release -DLLVM_USE_SANITIZER=Address -DLLVM_USE_SANITIZER_COVERAGE=On -DLLVM_BUILD_RUNTIME=Off -DCMAKE_ASM_COMPILER=/home/nopea/LLVM/llvm_build/bin /clang -DCMAKE_CXX_COMPILER=/home/nopea/LLVM/llvm_build/bin/clang++ -DLLVM_TARGETS_TO_BUILD=X86 ../llvm-8.0.0/", I hope you can help me solve this problem, thank you.
