如何在 Linux 上从源代码安装 TBB 并使其工作 [英] How to install TBB from source on Linux and make it work

问题描述

我想知道如何从源代码安装 TBB 并使其在 Linux 系统上运行.我在使用它时遇到了一些问题，如果我通过包管理器安装 TBB，这些问题就不会出现.

在 TBB 网页中，有一些关于如何执行此操作的指南，例如设置 LD_LIBRARY_PATH 和 CPATH 变量，或获取 tbbvars.sh 文件.即使我这样做，当我尝试编译一个示例时，g++ 会说没有找到 tbb.

所以我的问题是，是否有一种简单的方法来设置所有内容(编译源代码，我应该设置哪些变量...)以便使用 TBB?

谢谢.

注意:提出这个问题时的库版本号是 2(如果我没记错的话).我已经亲自测试了 4.1 版之前的解决方案，但我认为它也适用于当前版本 4.2(更新 3)，因为构建方法保持不变.

解决方案

我已经提供了解决方案.我会把它贴在这里，这样它会帮助其他人解决这个话题.

1. 下载最新的稳定源代码并解压，即在~/tbbsrc

2. 在里面，输入 make.它应该开始编译 tbb 库和内存分配器.

3. 标题在 ~/tbbsrc/include

4. 在 ~/tbbsrc/build 里面将有两个新文件夹，一个用于发布版本，另一个用于调试版本.这些文件夹的名称类似于 architecture_ldVersion_g++Version_kernelVersion.

5. 我建议设置一些变量，例如在您的 ~/.bashrc 文件中，例如:

TBB_INSTALL_DIR = $HOME/tbbsrcTBB_INCLUDE = $TBB_INSTALL_DIR/包含TBB_LIBRARY_RELEASE = $TBB_INSTALL_DIR/build/RELEASE_FOLDERTBB_LIBRARY_DEBUG = $TBB_INSTALL_DIR/build/DEBUG_FOLDER

6. 让我们尝试一个简单的例子:

//main.cpp#include "tbb/task_scheduler_init.h";int main(int argc, char* argv[]) {//tbb::task_scheduler_init init(tbb::task_scheduler_init::automatic);//隐式 tbb::task_sheduler_init::automatictbb::task_scheduler_init 初始化；返回0；}

7. 以发布版本为例进行编译:

g++ main.cpp -I$TBB_INCLUDE -Wl,-rpath,$TBB_LIBRARY_RELEASE -L$TBB_LIBRARY_RELEASE -ltbb

<块引用>

注意:使用-Wl,-rpath,$TBB_LIBRARY_RELEASE，我们告诉动态链接器在哪里可以找到libtbb.so

8. 这应该没问题！

最好的问候！

不要输入make，而是输入make compiler=clang 或make compiler=clang stdlib=libc++

I would like to know how to install TBB from source and make it work on a Linux system. I have had some problems when it comes using it, problems that don't appear if I install TBB via the package manager.

In the TBB webpage, there are some guidelines on how about to do this, like setting the LD_LIBRARY_PATH and CPATH variables, or sourcing the tbbvars.sh file. Even if I do that, when I try to compile an example g++ says that tbb is not found.

So my question is, is there an easy way to setup everything (compile the source code, what variables should I set...) in order to use TBB?

Thanks.

NOTE: The library version number when this question was asked was 2 (if I recall correctly). I have personally tested the solution up to version 4.1, but I think it should work too for current version 4.2 (update 3) since the building method remains the same.

解决方案

I have come with the solution. I'll post it here so it will help others with this topic.

1. Download the latest stable source code and uncompress it, i.e in ~/tbbsrc

2. Inside, type make. It should start compiling the tbb library and the memory allocators.

3. The headers are in ~/tbbsrc/include

4. Inside ~/tbbsrc/build will be two new folders, one for the release version and the other for the debug version. Those folders are named like architecture_ldVersion_g++Version_kernelVersion.

5. I recommend setting some variables, for example in your ~/.bashrc file, like:

TBB_INSTALL_DIR = $HOME/tbbsrc
TBB_INCLUDE = $TBB_INSTALL_DIR/include
TBB_LIBRARY_RELEASE = $TBB_INSTALL_DIR/build/RELEASE_FOLDER
TBB_LIBRARY_DEBUG = $TBB_INSTALL_DIR/build/DEBUG_FOLDER

6. Let's try a simple example:

// main.cpp
#include "tbb/task_scheduler_init.h"

int main(int argc, char* argv[]) {
    // tbb::task_scheduler_init init(tbb::task_scheduler_init::automatic);
    // implicit tbb::task_sheduler_init::automatic
    tbb::task_scheduler_init init;
    return 0;
}

7. To compile, for example, with the release version:

g++ main.cpp -I$TBB_INCLUDE -Wl,-rpath,$TBB_LIBRARY_RELEASE -L$TBB_LIBRARY_RELEASE -ltbb

Note: with -Wl,-rpath,$TBB_LIBRARY_RELEASE, we are telling the dynamic linker where to find libtbb.so

8. And that should work fine!

Best regards!

Instead of typing make, type make compiler=clang or make compiler=clang stdlib=libc++
