问题描述
我在我的IDE中有一个项目。我需要使它的共享库在扩展中使用。我不想使用共享库设置复制此项目。有没有办法使用目标文件（.o）从我已经存在的项目构建共享库？正如我所知，我可以为这个写一个makefile。
I have a project in my IDE. I need to make a shared library of it to use in extensions. I don't want to make a copy of this project with shared-library settings. Is there any way to build a shared library using the object files (.o) from my already existing project? As I understand, I can write a makefile for this.
推荐答案
我假设你在某种Unix上，使用GNU工具链。在这种情况下，要创建正确的共享库，您需要使用位置无关代码标志（-fpic或-fPIC）编译代码，然后才能创建共享库。除非你的.o文件已经用这些标志编译，你很可能不会有一个工作的共享库。
I assume you're on some sort of Unix and are probably using the GNU toolchain. In that case, to create a proper shared library, you'd need to compile your code using the position-independent code flags (-fpic or -fPIC) before you can create a shared library. Unless your .o files are already compiled with those flags, chances are you won't end up with a working shared lib.
如果它们已经编译为位置独立代码，通常的 g ++ -shared ... 应该做的。
If they already are compiled for position independent code, the usual g++ -shared ... should do the trick.
