如何使用 .so 文件而不在命令行中运行 g++
我创建了一个名为 car.so 的 .so 文件。我想在 test.cc 代码中测试和使用这个库。在命令行中我想编译：g++ test.cc -o test.我不想也链接（包含）库 car.so。
怎么做呢？
我的 test.cc 代码如下所示：
void* handle = dlopen("/home/v3/car.so", RTLD_LAZY);
Car* (*create)();
void (*destroy)(Car*);
create = (Car* (*)())dlsym(handle, "create_object");
destroy = (void (*)(Car*))dlsym(handle, "destroy_object");
Car* carr = (Car*)create();
carr->brake();
destroy( carr );
我还想问一下是否可以在一个 .so 文件中包含 3 个 .so 文件。

I've created a .so file called car.so. I would like to test and work with this library in a test.cc code . In the command line i would like to compile: g++ test.cc -o test. I don't want to also link (include) the library car.so.
How to do that?
My test.cc code looks like this:
void* handle = dlopen("/home/v3/car.so", RTLD_LAZY);
Car* (*create)();
void (*destroy)(Car*);
create = (Car* (*)())dlsym(handle, "create_object");
destroy = (void (*)(Car*))dlsym(handle, "destroy_object");
Car* carr = (Car*)create();
carr->brake();
destroy( carr );
I would also like to ask if it's possible to include 3 .so file in a single .so file.

一般来说，您应该在（应用程序）/ test.cc 中包含 .so 库的 .h 文件，然后通过链接该 .so 文件和 来编译该 test.cc 文件。使用生成的二进制文件。
我认为这个链接真的会对你有帮助..

in General you should include .h file of your .so library in your (application)/ test.cc then compile that test.cc file by linking that .so file & use generated binaray.
i think this link will realy help you..
