【问题描述】:
我在尝试编译 CUDA 程序时收到以下消息:
/usr/bin/ld: 找不到-lcudart
以前从未遇到过这种错误。我的 PATH 有什么问题吗?
这是编译命令:

编辑:
我已将链接命令更改为
gfortran -g -O2 -ffree-line-length-none -I../shared/ -L$CUDA_HOME/lib [其余如下]
我的所有 PATH 似乎都正常,但我仍然遇到同样的错误。
编辑2:
错误是我试图编译的代码是 64 位的,所以我需要为路径提供一组不同的 .so ,它们位于
/usr/local/cuda/lib64
现在编译运行良好,没有任何问题。
【问题讨论】:
-
你能发布你正在使用的编译命令或makefile吗?
-
当然,但它确实有点大......
-
你安装了 CUDA
toolkit吗? -
当然,我已经将它与 CUDA 本身一起安装了
