CUDA collect2 ld返回1退出状态

标签: hyperlink compilation cuda mars

我正在尝试为cuda 4.2.9编译火星(cuda 5.0消除了很多火星使用的头文件)。低于5.0的版本似乎利用了这个怪异的makefile common.mk,我很难配置它以使代码工作。目标文件编译得很好,但是我收到了这个错误:

/usr/lib64/gcc/x86_64-suse-linux/4.6/../../../../x86_64-suse-linux/bin/ld: cannot find -lcutil_x86_64
/usr/lib64/gcc/x86_64-suse-linux/4.6/../../../../x86_64-suse-linux/bin/ld: cannot find -lshrutil_x86_64
collect2: ld returned 1 exit status
make: *** [/home/ian/code/cuda-4.2.9/C/bin/linux/release/MatrixMul] Error 1

为什么会这样?我该如何解决这个问题?

这是MatrixMul的makefile:

为什么会这样?

libcutil_x86_64.liblibshrutil_x86_64.lib是由cuda样本构建的库(在cuda 4.2及更早版本中称为CUDA SDK),在CUDA SDK之后执行了正确的make操作时安装。链接器无法找到这些库,因此会抛出这些错误。

  

我该如何解决这个问题?

  1. 确保已正确安装CUDA 4.2 SDK,并且已完成必要的make操作以构建示例,因此构建必需的库。如果您不确定如何安装CUDA SDK或制作示例代码,请查看/home/ian/code/cuda-4.2.9/CUDA_SDK_Release_Notes.txt文件(尤其是Linux安装说明)。您可能还对该目录中的GPU_COMPUTING_SDK_Description.rtf文件以及.../doc/release子目录中的文件感兴趣。如果您没有正确构建样本,那么这些库将不可用,您将无法链接自己的matrixMul-MARS项目。请注意,您可以指定安装CUDA SDK的目录路径。我们假设从这里开始,路径中的...表示您的SDK安装路径(可能是/home/ian/code/cuda-4.2.9/NVIDIA_GPU_Computing_SDK或类似的东西。)如果您已经拥有的东西混乱,您可能想要开始干净并重新运行安装程序。
  2. 为matrixMul-MARS项目创建一个新项目目录,与其他C源项目目录处于同一级别,即.../C/src/myMARS或类似名称。
  3. .../C/src/matrixMul目录中的所有文件复制到新的.../C/src/myMARS目录中。
  4. 对新项目目录中的Makefile进行必要的更改(仅限)与此处显示的内容相对应,例如包含要构建的其他文件等。您不应该进行更改对common.mk的任何更改。
  5. 现在在新项目目录中执行make
