plugin1.cpp的析构函数:dlclose()不会调用全局对象
#include <iostream>
static class TestStatic {
public:
TestStatic() {
std::cout << "TestStatic create" << std::endl;
}
~TestStatic() {
std::cout << "TestStatic destroy" << std::endl;
}
} test_static;
host.cpp
#include <dlfcn.h>
#include <iostream>
int main(int argc,char *argv[]) {
void* handle = dlopen("./plugin1.so",RTLD_NOW | RTLD_LOCAL);
dlclose(handle);
return 0;
}
构建和运行:
>g++ -c plugin1.cpp -o plugin1.o -fPIC
>g++ -shared plugin.o -o plugin1.so
>g++ host.cpp -o host -ldl
>./host
>TestStatic create
>Segmentation fault
为什么TestStatic :: 〜TestStatic在'exit()'处调用,但不在'dlclose()'处调用?
