Introduction

Program that uses thread can crashes if statically linked.

Minimal program to test the faillure

#include <condition_variable>
int main() {
  std::condition_variable a;
  return 0;
}

Makefile

bin/static_link_failure: static_link_failure.cpp
	g++ --std=c++11 -static -pthread $^ -lpthread -o $@.g++.static
	clang++ --std=c++11 -static -pthread $^ -lpthread -o $@.clang++.static
	g++ --std=c++11 -pthread $^ -lpthread -o $@.g++.non_static
	clang++ --std=c++11 -pthread $^ -lpthread -o $@.clang++.non_static
	clang++ --std=c++20 -pthread $^ -lpthread -o $@

output/static_link_failure.txt: bin/static_link_failure
	echo "bin/static_link_failure.g++.static" > $@
	bin/static_link_failure.g++.static         || echo "FAIL" >> $@
	echo "bin/static_link_failure.clang++.static" >> $@
	bin/static_link_failure.clang++.static     || echo "FAIL" >> $@
	echo "bin/static_link_failure.g++.non_static" >> $@
	bin/static_link_failure.g++.non_static     || echo "FAIL" >> $@
	echo "bin/static_link_failure.clang++.non_static" >> $@
	bin/static_link_failure.clang++.non_static || echo "FAIL" >> $@

Possible output

bin/static_link_failure.g++.static
bin/static_link_failure.clang++.static
bin/static_link_failure.g++.non_static
bin/static_link_failure.clang++.non_static
