使用C绑定库进行链接

Question

我正在尝试与下一个库链接：(请参阅文档)

这是一个用C++编写的库的C绑定。但如果制作静态库，然后尝试链接到它。

我会收到以下信息：

如果我创建了一个共享库并尝试在我的程序中使用它，编译时没有问题，但是运行时出现以下错误：

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

我这样编译：

我以这种方式编译：

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

好的！这个可行！

LD_LIBRARY_PATH=uchardet/ ./a.out

但是我能在这里使用静态链接吗？

如果您能包含更多的错误输出以及一个小的示例来说明*您是如何链接它的，那将会很有帮助。我也假设您正在将其链接到您的C程序中;-)。 - anoneironaut

你可以尝试像这样做：LD_LIBRARY_PATH=/location/where/lubuchardet ./your_exe 或者 export LD_LIBRARY_PATH=...。另一种选择是静态链接，它会将库放在可执行文件中（消除了对 LD_LIBRARY_PATH 的繁琐操作）。 - user1508519

“我做错了什么？” - 可能你链接时使用了 gcc，而不是 g++。 - user529758

是的，但它是一个C绑定。应该可以使用gcc编译，不是吗？ - Leonid

remyabel，你的建议很有帮助，但是在静态链接时如何处理未定义引用？ - Leonid

Answer 1

对于共享库的情况：默认情况下，RTLD仅适用于公共库搜索路径。如果要添加另一个路径，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

这个选项将要求RTLD在指定的目录中搜索库。可以为每个附加目录多次指定此选项。

对于静态库案例发生了什么，您可以使用ldd来确定共享库所需的libg ++，libstdc ++或类似内容，具体取决于您的系统。如果是这样，您应该为链接添加其静态模拟。即使编译的是纯C代码，g ++也会自动执行此操作，但gcc 不会。

我又犯了低级错误，应该使用 g++ 而不是 gcc。 - Navin
