Title Body

Getting this error while compiling C++ code: undefined reference to `__stack_chk_fail' Options already tried: added -fno-stack-protector while compiling - did not work, error persists added a dummy implementation of void __stack_chk_fail(void) in my code. Still getting the same error. Detailed Error: /u/ac/alanger/gurobi/gurobi400/linux64/lib/libgurobi_c++.a(Env.o)(.text+0x1034): In function `GRBEnv::getPar/u/ac/alanger/gurobi/gurobi400/linux64/lib/libgurobi_c++.a(Env.o)(.text+0x1034): In function `GRBEnv::getParamInfo(GRB_StringParam, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)': : undefined reference to `__stack_chk_fail' amInfo(GRB_StringParam, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)': : **undefined reference to `__stack_chk_fail'** Earlier, I was getting 10's of such errors. Found out that there was a version mismatch between the gcc of the pre-compiled libraries I am using and the gcc version I was using to compile the code. Updated gcc and now I am getting only 2 of these errors. Any help, please?
