11 months ago Try adding nostdinc++ in sym++ script.
stdlib_cflags="-isystem ${!libcxx_var}/include/c++/v1 -nostdinc++ -nostdlib++"Ref: https://releases.llvm.org/16.0.0/projects/libcxx/docs/UsingLibcxx.html#using-a-custom-built-libc
I am using symcc to analyze C++ programs with libcxx. I follow the document c++.txt in docs. Firstly, I compile and instrument libcxx using sym++ and install the instrumented libcxx to path: /home/user/programs/libcxx_install Then I use sym++ to compile my target c++ program main.cpp. But I get the following error. It seems that some headers files are missed.
By the way, I can compile and install libcxx without symcc. The uninstrumented libcxx works well on my computer. I can also use standard cxx library by setting SYMCC_REGULAR_LIBCXX=yes.
The errors are as follows.
