无法将英特尔 TBB 库与 /usr/lib 中的 libtbb 链接

Question

我从英特尔的 TBB 网站下载了英特尔 TBB 的预构建头文件和库。我更新了 ldconfig 以将 tbb 共享库添加到 /usr/lib。但是在使用 -tbb 编译时，使用 g++ ld 的代码会返回 -1，因为它无法找到 libtbb

libtbb.so.2 存在于 /usr/lib/

这是我完整的 g++ 输出

g++ hellotbb.cpp  -o htbb -I$HOME/libs/tbb43/include  -v  -ltbb 

Using built-in specs.

ld 好像没有在 /usr/lib/ 中检测到我的 tbb 库

Answer 1

确保libtbb.so 也存在并在需要时安装libtbb-dev 包：

apt-get install libtbb-dev

顺便说一句，您的包含文件位于可疑位置。看起来您混合安装了 TBB 二进制文件并包含来自不同来源的文件。这可能会导致严重的问题，尤其是如果标头比二进制文件更新。
