c++ - 与库的 c 绑定(bind)链接

Question

我正在尝试链接到下一个库:( see docs )

它是一个 C 绑定(bind)，用于用 C++ 编写的库。但是如果制作静态库然后尝试链接到它。

我收到这些消息:

collect2: error: ld returned 1 exit status

如果 make shared one 并尝试在我的程序中使用它，它会编译，但是当我运行它时，我有:

error while loading shared libraries: libuchardet.so.0: cannot open shared object file: No such file or directory

我是这样编译的:

gcc test.c  -Ithird -Lthird/parserutils/lib_amd64/ -lparserutils -I uchardet/ -L uchardet/ -luchardet

好的!这行得通!

LD_LIBRARY_PATH=uchardet/ ./a.out

但是我可以在这里使用静态链接吗？

Answer 1

对于共享库案例:默认情况下，RTLD 仅应用公共(public)库搜索路径。要添加另一个，请在链接二进制文件时添加一个选项:-Wl,-rpath=$libdir，例如

gcc test.c  -Ithird -Lthird/parserutils/lib_amd64/ -lparserutils -I uchardet/ -L uchardet/ -luchardet -Wl,-rpath=`pwd`/uchardet

此选项将要求 RTLD 也在指定目录中搜​​索库。可以为此处调用的每个附加目录指定多次。

静态库情况发生了什么，您可以确定对共享库使用 ldd。它很可能需要 libg++、libstdc++ 或模拟，具体取决于您的系统。如果是这样，您还应该为您的链接添加其静态模拟。即使编译了纯 C 代码，g++ 也会自动执行此操作，但 gcc 不会。
