AFLGO_TRACING error #16
Comments

I changed the createglobalstrptr to GlobalVariable, but a new error comes as follows. I'm using llvm 7.0. I want to know what version of llvm you used. -- Building tiff version 4.0.7 It fails with the following output: Change Dir: /home/lt/libtiff/tiff-4.0.7-save-temp/aflgo-build/CMakeFiles/CMakeTmp Run Build Command:"/usr/bin/make" "cmTC_04bdf/fast" /usr/bin/make -f CMakeFiles/cmTC_04bdf.dir/build.make make[1]: Entering directory Building C object CMakeFiles/cmTC_04bdf.dir/testCCompiler.c.o /home/lt/aflgo-org/afl-clang-fast Linking C executable cmTC_04bdf /usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_04bdf.dir/link.txt /home/lt/aflgo-org/afl-clang-fast /usr/bin/ld.gold: fatal error: Failed to link module clang-7.0: error: linker command failed with exit code 1 (use -v to see CMakeFiles/cmTC_04bdf.dir/build.make:97: recipe for target 'cmTC_04bdf' make[1]: *** [cmTC_04bdf] Error 1 make[1]: Leaving directory Makefile:126: recipe for target 'cmTC_04bdf/fast' failed make: *** [cmTC_04bdf/fast] Error 2 CMake will not be able to correctly generate this project. -- Configuring incomplete, errors occurred! |

hi @levi-2018 There could be some LLVM-version specific issue that we have not encountered. We tested our tool mostly with LLVM 3.8 and LLVM 4.0. |
|
Ok, I'll try it with LLVM 4.0. Thank you. |
Hi, if I define AFLGO_TRACING in afl-llvm-pass.so.cc file, there is always an error as follows when i using afl-clang-fast to compiler libtiff-4.0.7.
