Error with linking to cudnn on windows
coreylowman opened this issue · comments
@sololist-v posted this in a dfdx issue:
Can CUDNN_INCLUDE and CUDNN_LIB be added to respectively specify the include and lib directories?
Because I am unable to specify the lib directory on Windows, I need to copy the CUDNN lib files to the project directory in order to compile.
Yes, the error message is "LINK: fatal error LNK1181: cannot open input file 'cudnn.lib'". In fact, if you want to use cl.exe, you also need to execute "cmd /k "D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"" in the command prompt before running "cargo run" in a new terminal, otherwise you may encounter an error saying that cl.exe cannot be found.
I am able to compile on Windows without doing anything extra. Perhaps I already have these libraries on PATH?
cudnn path:
D:\PROGRAM FILES\CUDNN
└─cuda
├─bin
├─include
├─lib
└─zlib123dllx64
├─dll_x64
│ └─demo
└─static_x64
my_project/.cargo/config.toml
[env]
CUDNN_LIB = "D:/Program Files/cudnn/cuda"
cargo clean
cargo build
output:
error: linking with link.exe failed: exit code: 1181

This may be a case of missing a candidate lib sub directory. @soloist-v Can you post where exactly your cudnn.lib files are under your CUDNN directory?
Right now build.rs looks under these candidates:
"lib/x64",
"lib/Win32",
"lib/x86_64",
"lib/x86_64-linux-gnu",
"lib64",
"lib64/stubs",
"targets/x86_64-linux",
"targets/x86_64-linux/lib",
"targets/x86_64-linux/lib/stubs",Can the search path be extended by the environment variable CUDNN_LIB?
It already is - but we need to augment CUDNN_LIB path with the lib directory, which is different on each platform. That's what the list I posted above is (they are all relative to CUDNN_LIB).
Can you post directory tree under your lib/ dir?
Of course, this is my lib directory information.

There are no directories in the lib directory.
Ooooh yep that's why then!
Okay if you want to test out the main branch of cudarc, it should be resolved now. Please reopen if it isn't resolved
Thank you, and I think there are no more problems.
