Question

我在ubuntu 12.04中遇到了一些问题。

我想在我的代码:: blocks project中使用SFML库。

在SFML文件夹中有两个子文件夹 - 包含和 lib 。 include包含头文件（.h文件）。 lib包含库文件（.so文件）。

我无法直接将库链接到我的项目，因为编译器找不到文件。

我在谷歌研究并发现我必须将sfml文件放在标准路径中，以便在代码块中正确链接它们。那么我应该把这些文件放在哪个默认标准位置？

编辑：在进行了大量的谷歌搜索之后，我开始知道如何将标题和模块放在正确的标准位置。但是在编译和运行后（从代码块或从终端），这些未定义的引用错误即将来临： -

Answer 1

您可以将 include 文件夹的内容放在 / usr / include 或 / usr / local / include 中，以及 / usr / lib 或 / usr / local / lib

中的 lib 文件夹

您还可以在编译代码时指定include和libraries路径。例如，如果您使用gcc，则可以执行此操作：

gcc prog.c -oprog -I/path/to/include/folder -L/path/to/libraries/folder -lLibraryName.so

在ubuntu中，我应该在哪里放置这些文件？
