Question

编辑：这似乎是一个长期存在的问题，没有迫在眉睫的解决方案： http://d.puremagic.com/issues/show_bug.cgi?id=8133 http://www.digitalmars.com/d/archives/digitalmars/D/Ideas_for_runtime_loading_of_shared_libraries._154126.html http://lists.puremagic.com/pipermail/dmd-internals/2011-December/002853.html

在c程序中加载的d dylib中启动d运行时似乎存在问题。每当我调用Runtime.initialize（）时，我都会遇到段错误。

C代码：

#include <stdio.h>
#include <dlfcn.h>

int main() {
    void *library;
    int (*fptr)();
    library = dlopen("testlib.dylib", RTLD_LAZY);
    if(library == NULL)
        puts("couldn't load the library");
    else {
        *(void **)(&fptr) = dlsym(library,"number");
        if(fptr == NULL) {
        puts("couldn't load function");
        } 
        else {
            printf("the result is %d\n",(*fptr)());
        }
    }
    return(0);
}

使用gcc编译，没有标记。

代码：

import core.runtime;

extern(C) int number() {
    Runtime.initialize();
    return(4);
}

使用dmd -shared编译

回溯：

Program received signal EXC_BAD_ACCESS, Could not access memory.

在OS X 10.7中完成所有编译和调试

注意：如果是Runtime.initialize（）; line已注释掉，库已加载并正确运行。
