Hi,
did you read this C++.txt ?
I'm not sure SYMCC_REGULAR_LIBCXX=1
is equivalent to SYMCC_REGULAR_LIBCXX=yes
.
Did you try the procedure with the instrumented libC++?
If none of the above works, could you try to provide a minimal test case?

Yes,i try the procedure with the instrumented libC++,after i set SYMCC_LIBCXX_PATH=/path-provided-as-cmake-install-prefix-for-libcxx in the environment,the problem is solved.Thanks!!
I have another question. I encountered the same problem as this during the fuzzing process. Is there a solution to this problem now?
Thanks. Good to know. for #45 you can try to use patches that are in this branch https://github.com/vanhauser-thc/symcc
Hello,symcc team I try to combine symcc and afl by symcc_fuzzing_helper,When I use symcc to compile the C project, there is no problem.However, the following problems will occur when compiling C++ projects.
I try to fix it with SYMCC_REGULAR_LIBCXX=1 set in the environment,it worked.But when the program compiled by sym++ is run with afl, the output is all like this
Projects complied with symcc(c compiler) can correctly generate test cases, so i think there must be something wrong with it.Could you tell me how to fix it?
