    我想知道我丢失了哪些文件。我应该重建SpiderMonkey并将其安装在
    /usr/local
    中吗?任何帮助都将不胜感激

    我很确定问题不在于我使用的是静态库。我将SpiderMonkey重新构建为共享对象库,但它仍然给了我相同的错误。

    您可以尝试以下操作:

    g++ -I/home/aaditmshah/js/include/js /home/aaditmshah/js/lib/mozjs185-1.0.a -lm -ldl helloworld.cpp -o helloworld
    
    直接在g++命令行中添加归档文件。如果它不起作用,您可能需要指定这些的一些组合。(对于gcc 4.2,这对我来说很有效):


    只需在Ubuntu 12.10、g++版本gcc 4.7.2(Ubuntu/Linaro 4.7.2-2ubuntu1)上为mozjs185-1.0.a.

    指定正确的路径SipderMonkey v1.8.5:命令是
    sudo g++-o helloworld-I/usr/local/include/js helloworld.cpp-lmozjs185-1.0-L/usr/local/lib-lpthread
    花费比预期更多的时间做这么简单的事情!不感谢FireFox/Mozilla。

    我真的很抱歉这么说,但这对我来说很好。我得到了两个C++警告,但没有链接错误。生成的可执行文件运行良好。我在Mac电脑上。您可能希望查看
    nm libmozjs185-1.0.a | grep JS_NewContext
    的输出。我得到一行,上面写着
    00000000000016d0t\u JS\u NewContext
    。我得到一行,上面写着
    0000000000003500 T JS\u NewContext
    ,我假设这意味着
    JS\u NewContext
    的值为
    13568
    。我不知道该如何处理这个输出。不,它仍然不起作用。选项
    -lm
    -ldl
    是什么意思?我使用的是g++version
    g++-4.6.real(Ubuntu/Linaro 4.6.1-9ubuntu3)4.6.1
    g++ -I/home/aaditmshah/js/include/js /home/aaditmshah/js/lib/mozjs185-1.0.a -lm -ldl helloworld.cpp -o helloworld
