[Bug] Can't finish the build process on windows about mlc-llm

[tqchen]

the error was due to lack of cmake dependency, can you install cmake via conda?

Thank you for your feedback. I did that but it's failing now somewhere else.
I am going to try on a linux machine.

Facing the same issue here.

I'm not sure what I'm doing any wrong, any help would be greatly appreciated.

what is that win2 error file not found the model was compiled but it should be packaged to create appication using android studio right?? but its not packaging i tried in windows , linux i tried first compiling with mlc_llm compile comand and give the path of compiled model in mlc-package-config.json file still its showing error file not found

[tqchen]

in this case, seems you didn't specify TVM_NDK_CC env variable to the right compiler

I specified same as in the mlc-llm official document like TVM_NDK_CC: %ANDROID_NDK%/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android24-clang I tried this path I tried with normal clang path I tried with clang++ path even though it’s not working

[tqchen]

In this case it was looking for llvm-ar, please check if you have llvm-ar in that path

If you can list files under %ANDROID_NDK%/toolchains/llvm/prebuilt/windows-x86_64/bin that would be helpful to see if you can find files similar to llvm-ar

[Nikhil34712]

yeah llvm-ar is available in same path though its not working

Thanks @Nikhil34712 , do you mind go into file ndk.py as indicated in the error message and print out the cmd. See there is a subprocess.Popen, you can try to print out cmd part and see what it tries to do. Then it should give hints about why it fails
