Team, I'm trying to get a simple coroutine2 program to work with address sanitizer and I'm running into a block. I'm building boost_1_78_0 as follows: ./b2 context-impl=ucontext and compiling with -DBOOST_USE_ASAN and -DBOOST_USE_CONTEXT. I've built and rebuilt the library thinking I've made an error somewhere and it boils down to jump_fcontext and make_fcontext. What am I doing wrong/missing? Cheers, TJ g++ -DBOOST_USE_ASAN -DBOOST_USE_UCONTEXT -I/home/tjisana/Downloads/boost_1_78_0 -O0 -g3 -fsanitize=address -pedantic -Wall -c -fmessage-length=0 -o src/Testbed II.o ../src/Testbed II.cpp g++ -L/home/tjisana/Downloads/boost_1_78_0/stage/lib -fsanitize=address -o Testbed II src/Testbed II.o -lboost_context -lboost_coroutine /usr/lib64/gcc/x86_64-suse-linux/11/../../../../x86_64-suse-linux/bin/ld: /home/tjisana/Downloads/boost_1_78_0/stage/lib/libboost_coroutine.so: undefined reference to `jump_fcontext' /usr/lib64/gcc/x86_64-suse-linux/11/../../../../x86_64-suse-linux/bin/ld: /home/tjisana/Downloads/boost_1_78_0/stage/lib/libboost_coroutine.so: undefined reference to `make_fcontext' collect2: error: ld returned 1 exit status #include <queue> #include <memory> #include "boost/coroutine2/coroutine.hpp" typedef boost::coroutines2::coroutine<int> coro_t; int main() { int l = 0; std::queue<int> y({1,2,3,4}); std::queue<std::unique_ptr<int>> w; coro_t::push_type sink([&](coro_t::pull_type& source) { for (const auto& i : source) { while (!w.empty()) { auto ptr = std::move(w.front()); w.pop(); if (*ptr == 1) { std::cout << "first: " << i << std::endl; auto item = 21; w.push(std::move(std::make_unique<int>(item))); } else if (*ptr == 21) { std::cout << "second: " << i+2*i << std::endl; auto item = 32; w.push(std::move(std::make_unique<int>(item))); } else if (*ptr == 32) { std::cout << "third: " << i*i << std::endl; } } } source(); }); while (!y.empty()) { if (!y.empty()) { l = y.front(); y.pop(); w.push(std::move(std::make_unique<int>(1))); sink(l); } } return 0; }
