Question

我读了这些帖子：

但仍然出现此错误：

   piCalc.cpp:8:17: fatal error: ttb.h: No such file or directory
 #include "ttb.h"

我计算pi的代码以

开头

#include <iostream>
#include "ttb.h"
#include "parallel_for.h"

安装了nvidia和cuda运行Ubuntu 14.04。要安装TBB，我开始使用：

sudo apt-get install libtbb-dev

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.

所以我觉得我很高兴。所以，我试过了：

g++ piCalc.cpp -ltbb -o pi

并得到错误。所以我从intel下载了存档，并将其解压缩到我的主目录，进入名为tbb的目录。

发出ls给出：

CHANGES  COPYING  README  bin  doc  examples  include  index.html  lib  piCalc.cpp

注意piCalc.cpp位于tbb目录中。此外，tbb.h位于/ include / tbb 所以我将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

我的终端命令如此发布：

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

以及

g++ piCalc.cpp  -o pi -I /include/tbb -L /lib/intel64/gcc4.4 -ltbb

发生同样的错误

piCalc.cpp:8:30: fatal error: /include/tbb/ttb.h: No such file or directory
 #include "/include/tbb/ttb.h"

我尝试了绝对路径：

g++ piCalc.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi

仍然是同样的错误。

我尝试将代码更改为：

#include <iostream>
#include </home/stefan/tbb/include/tbb/ttb.h>
#include </home/stefan/tbb/include/tbb/parallel_for.h>

得到这个：

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.

基本上是相同的错误，但由于我在终端命令中使用了绝对路径，因此更加冗长。

我想也许LD_LIBRARY_PATH变量很重要。 CUDA使用LD_LIBRARY_PATH变量混乱，所以我导出了intel libs，现在printenv显示：

LD_LIBRARY_PATH=/home/stefan/tbb/lib/intel64/gcc4.4:/usr/local/cuda-7.5/lib64:

仍然收到错误。

这是详细错误：

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，也会出现此错误。我还尝试了括号而不是源代码中包含文件的引用。

由于我的大脑现在处于深刻的状态，我希望有人能指出我所缺少的东西来帮助我。

Answer 1

最后，我想通了，所以我在这里发帖，所以其他任何人都可能受益。

1) download the Intel libraries from [here][1]

2) extract the folder and rename it to tbb

3) move that folder into /usr/local

4) in source use:  #include <tbb/tbb.h>

5) g++ test.cpp -o program -ltbb

无法链接INTEL tbb库
