尝试交叉编译 CUDNN 示例时：
cp -r /usr/src/cudnn_samples_v8/ $HOME
cd $HOME/cudnn_samples_v8/mnistCUDNN
make clean
make TARGET_ARCH=aarch64 SBSA=1
错误如下：
CUDA_VERSION is 12020
Linking agains cublasLt = true

libfreeimage3 libfreeimage-dev 已安装：
上述输出中的“ collect2: error: ld returned 1 exit status”是什么意思？如何查找原因？
答案1
这GNU 链接器(ld）是一个工具（其中之一) 在编译过程中调用，从项目中创建/调用的目标文件创建可执行文件。
collect2是收集/检查链接器输出的工具。
collect2: error: ld returned 1 exit status
只是意味着上述链接操作没有成功，但这不是导致编译操作失败的真正原因，而是以前的错误的结果，您需要注意这些错误...例如：
cannot find -lfreeimage: No such file or directory
更多信息请参阅：
>>> WARNING - FreeImage is not set up correctly. Please ensure FreeImage is set up correctly. <<<
注意：libfreeimage系统上的可用性可能不是导致该错误的唯一原因，但可能需要一些其他相关库，例如libcudnn（部分灵感来自于你用nvidia) 取决于您的项目。
