[TVM Discuss] [Application] Building TVM with 'c' runtime support
Hi all,
I see that TVM can lower a tensor computation c code. However when I try to execute this lowered c code, TVM throws an error saying "C Source module cannot execute, to get executable module build TVM with 'c' runtime support". How do I go about building TVM with the said 'c' runtime support?
Thanks!

you can call into the specific name you pass to the build function `tvm.build(..., name="myfunc")`.
```
mod["myfunc"](args)
```

I could export and import the shared object, but I'm unsure about how to invoke the function in the library. I'm getting an error now which says "Check failed: entry_name!= nullptr: Symbol __tvm_main__ is not presented". Is there a shim or something what I'm supposed to call?

We will need to export the library as a shared library before executing it. You can do `lib.export_library("xyz.so")` then load it back
