clFFT编译问题：对`clGetPlatformInfo'和其他OpenCL函数的未定义引用

标签： cmake compiler-errors shared-libraries opencl

我尝试构建clFFT库（用于使用OpenCL进行FFT）和包含在clFFT git中的示例。

1）首先，我进入/opt/：

git clone https://github.com/clMathLibraries/clFFT.git

2）之后，我总是进入/opt/目录：$ mkdir build && cd build/

3）从这里，我这样叫cmake：

cmake -DOpenCL_INCLUDE_DIR=/opt/AMDAPPSDK-3.0/include -DOpenCL_LIBRARY=/opt/AMDAPPSDK-3.0/lib/x86_64 ../clFFT/src/

实际上，我已经从/opt/归档文件中安装了AMDAPPSDK-3.0到AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2目录中。

4）一切似乎对于clFFT的编译都是有效的，但失败了：

4.1）首先，在上述cmake命令的末尾，我得到：

 cmake -DOpenCL_INCLUDE_DIR=/opt/AMDAPPSDK-3.0/include -DOpenCL_LIBRARY=/opt/AMDAPPSDK-3.0/lib/x86_64 ../clFFT/src/

更准确地说，我是在谈论：

4.2）在启动make到/opt/build/目录之后，我收到以下警告：

我不知道这些错误可能来自何处，似乎我建立的库libclFFT.so.2.14.0不包含对OpenCL基本功能的引用（例如clGetPlatformIDs或{{1} } ...）。

此外，我不知道为什么未定义引用的路径是上一级，即clCreateCommandQueue，因为该库内置在/usr/bin/ld: ../library/libclFFT.so.2.14.0目录中

考虑到路径/opt/build/library指示的OpenCL标头和libclFFT.so指示的库，我希望能够对OpenCL_INCLUDE_DIR进行精细的编译。

我必须解决OpenCL_LIBRARY所采取的路径问题，即cmake，并将../library/libclFFT.so.2.14.0 SDK中的所有OpenCL函数包含到该库的构建中。

欢迎您的帮助，

您计算机上的mypalette=rep("Green",length(Days)) mypalette[Days <= 25] = "Pink" mypalette[Days <= 15] = "Orange" mypalette[Days <= 5] = "Blue" mypalette[is.na(Days)] = "Red" 安装程序应具有一个OpenCL查找程序，当 window.onload= function (){ var paper = new Raphael( 0, 0, 800, 600); var backGround = paper.rect(0,0,800,600); backGround.attr({ fill: "blue"}); /* Comment - Add your code here*/ var ball = paper.circle(0,0,30); ball.attr({ fill: "black"}); function position1() { ball.animate({cy: 150 , cx: 250 }, 500, 'ease-in', position2); } function position2() { ball.animate({cy: 105 , cx: 309}, 500, 'ease-in', position3); } function position3() { ball.animate({cy: 100 , cx: 400}, 500, 'ease-in', position4); } function position4() { ball.animate({cy: 120 , cx: 490}, 500, 'ease-in', position5); } function position5() { ball.animate({cy: 520 , cx: 190}, 500, 'ease-in', position6); } function position6() { ball.animate({cy: 300 , cx: 540}, 500, 'ease-in', position7); } function position7() { ball.animate({cy: 410 , cx: 450}, 500, 'ease-in', position8); } function position8() { ball.animate({cy: 400 , cx: 300}, 500, 'ease-in', position9); } function position9() { ball.animate({cy: 305 , cx: 250}, 500, 'ease-in', position10); } function position10() { ball.animate({cy: 220 , cx: 230}, 500, 'ease-in', position1); } }; 从{{1}执行cmake文件时，该命令由find_package(OpenCL)命令调用}}分发（也可以在您自己的cmake文件中使用此命令）。该查找程序只是一个名为CMakeLists.txt的文件，该文件必须是clFFT配置的一部分。确保您拥有此文件：

CMakeLists.txt

如果拥有此查找程序，则无需在FindOpenCL.cmake调用中设置变量cmake和find /usr -name FindOpenCL.cmake -查找程序将找到所有所需的OpenCL路径。如果您有这个查找程序，但是它不能正常工作-那么对于它的开发人员来说将是个问题。如果您没有拥有此查找器，那么在OpenCL_INCLUDE_DIR安装和/或设置中将是一个问题。 here描述了该发现者。

根据我们在评论中的对话，您试图在MacOS上使用AMD APP SDK v3.0软件包-这是行不通的，因为AMD仅支持Windows和Linux操作系统。这是可以理解的，因为Apple拥有自己的OpenCL支持悠久的历史-请参阅here。
