问题描述
我读了这些主题:
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
#include <iostream>
#include "ttb.h"
#include "parallel_for.h"
运行装有nvidia和cuda的Ubuntu 14.04.要安装TBB，我从:
Running Ubuntu 14.04 with nvidia and cuda installed.To install TBB, I started with :
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.
所以我以为我很好.所以，我尝试了:
So I thought I was good to go. So, I tried:
g++ piCalc.cpp -ltbb -o pi
并得到错误.因此，我从intel下载了归档文件，并将其解压缩到我的主目录下，命名为tbb.
and get the error. So I downloaded the archive from intel and decompressed it to my home directory into a directory named tbb.
发出ls会给出:
CHANGES COPYING README bin doc examples include index.html lib piCalc.cpp
注意piCalc.cpp在tbb目录中.另外，tbb.h位于/include/tbb所以我将include语句更改为
Notice piCalc.cpp is in the tbb directory. Also, tbb.h is located at /include/tbbSo I changed the include statements to
#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
libtbb.so and libtbb.so.2 are located at lib/intel64/gcc4.4
我的终端命令是这样发出的:
My terminal command was issued thusly:
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
并且发生相同的错误
piCalc.cpp:8:30: fatal error: /include/tbb/ttb.h: No such file or directory
#include "/include/tbb/ttb.h"
我尝试了以下绝对路径:
I tried absolute paths with this:
g++ piCalc.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi
仍然是相同的错误.
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>
并得到这个:
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.
基本上相同的错误，但是更冗长，因为我在终端命令中使用了绝对路径.
Basically the same error but more verbose since I used the absolute path in the terminal command.
我认为LD_LIBRARY_PATH变量可能很重要. CUDA弄乱了LD_LIBRARY_PATH变量，因此我导出了Intel库，现在printenv显示了:
I thought maybe the LD_LIBRARY_PATH variable was important. CUDA messes with the LD_LIBRARY_PATH variable so I exported the intel libs and now printenv shows:
LD_LIBRARY_PATH=/home/stefan/tbb/lib/intel64/gcc4.4:/usr/local/cuda-7.5/lib64:
仍然出现错误.
以下是详细错误:
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，也会遇到此错误.我还尝试使用方括号代替源文件中包含文件的引号.
I also get this error if I copy the include/tbb folder which has all the .h files into the /usr/local/include folder. I also tried brackets instead of quote for the include files in the source.
由于现在我的大脑已陷入深深的车辙，所以我希望有人可以指出我所缺少的东西来为我提供帮助.
Since my brain is in a deep rut by now, I am hoping someone can help me by pointing out what I am missing.
推荐答案
最后，我想通了，所以我在这里发布，以便其他任何人都可以受益.
FINALLY, I figured it out so I am posting here so anyone else might benefit.
- 从此处下载
- 提取文件夹并将其重命名为tbb
- 将该文件夹移动到
/usr/local - 在源代码中使用:
#include <tbb/tbb.h> -
g++ test.cpp -o program -ltbb
- Download the Intel libraries from here
- Extract the folder and rename it to tbb
- Move that folder into
/usr/local - In source use:
#include <tbb/tbb.h> g++ test.cpp -o program -ltbb
