我阅读了以下帖子：
如何在Linux上使用gcc运行Thread Building Blocks（Intel TBB）
无法将Intel TBB库与/usr/lib中的libtbb链接
但仍然收到以下错误：
piCalc.cpp:8:17: fatal error: ttb.h: No such file or directory
#include "ttb.h"
我用来计算圆周率的代码从以下开始：
#include <iostream>
#include "ttb.h"
#include "parallel_for.h"
在安装了nvidia和cuda的Ubuntu 14.04上运行。为了安装TBB，我开始做如下操作:
sudo apt-get install libtbb-dev
并且它说：
Reading package lists... Done
Building dependency tree
Reading state information... Done
libtbb-dev is already the newest version.
The following package was automatically installed and is no longer required:
libxine2-bin
Use 'apt-get autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
所以我认为一切准备就绪，于是我尝试了：
g++ piCalc.cpp -ltbb -o pi
我遇到了一个错误，是和it技术有关的。所以我从Intel下载了压缩文件，并将其解压到我的主目录中，创建了一个名为tbb的目录。
执行ls命令得到：
CHANGES COPYING README bin doc examples include index.html lib piCalc.cpp
请注意，piCalc.cpp 文件位于 tbb 目录中。同时，tbb.h 文件位于 /include/tbb 下。 因此，我将 include 语句更改为：
#include <iostream>
#include "/include/tbb/ttb.h"
#include "/include/tbb/parallel_for.h"
libtbb.so和libtbb.so.2位于lib / intel64 / gcc4.4目录下。
我的终端命令如下：
g++ piCalc.cpp -o pi -I include/tbb -L lib/intel64/gcc4.4 -ltbb
以及
g++ piCalc.cpp -o pi -I include/tbb/ -L lib/intel64/gcc4.4/ -ltbb
同样也
g++ piCalc.cpp -o pi -I /include/tbb -L /lib/intel64/gcc4.4 -ltbb
同样的错误出现了
piCalc.cpp:8:30: fatal error: /include/tbb/ttb.h: No such file or directory
#include "/include/tbb/ttb.h"
我尝试使用绝对路径：
g++ piCalc.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi
依旧是同样的错误。
我尝试将我的代码更改为：
#include <iostream>
#include </home/stefan/tbb/include/tbb/ttb.h>
#include </home/stefan/tbb/include/tbb/parallel_for.h>
还有这个：
stefan@HN5:~/tbb$ g++ piCalc3.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi
piCalc3.cpp:8:46: fatal error: /home/stefan/tbb/include/tbb/ttb.h: No such file or directory
#include </home/stefan/tbb/include/tbb/ttb.h>
^
compilation terminated.
这基本上是相同的错误，但更详细，因为我在终端命令中使用了绝对路径。
我想也许 LD_LIBRARY_PATH 变量很重要。CUDA 会影响 LD_LIBRARY_PATH 变量，所以我导出了英特尔库，现在 printenv 显示如下：
LD_LIBRARY_PATH=/home/stefan/tbb/lib/intel64/gcc4.4:/usr/local/cuda-7.5/lib64:
我仍然收到错误信息。
这是详细的错误信息：
stefan@HN5:~/tbb$ g++ piCalc.cpp -o pi -v -I/home/stefan/tbb/include/tbb -L/home/stefan/tbb/lib/intel64/gcc4.4 -ltbb

如果我将包含所有.h文件的include/tbb文件夹复制到/usr/local/include文件夹中，我也会遇到这个错误。我还尝试过在源代码中使用括号代替引号来包含文件。
由于我现在已经很困惑了，希望有人能指出我缺少什么。
