Hi there, I would like to write something like this:

```
val fileSize = memScoped {
	val statBuf = alloc<stat>()
	val error = stat("/", statBuf.ptr)
	statBuf.st_size
}

```

However, upon compilation I get:

unresolved reference: memScoped, unresolved reference: alloc (etc…)

Which libraries would I need to import in order to use C functions with Kotlin? Googling this problem provides a “libcurl” example which isn’t useful at all. It also instructs to create a “def” file and include a header in order to make use of a particular C library function. However, there is no information on how to use memscope.

I have created my own scripts in Kotlin in order to compile with kotlinc, and it includes all needed libraries for my project in a folder.

I would appreciate your help, meanwhile thanks for your time and patience.

I had a similar issue. I fixed it by removing (reinstalling) the ~/.konan folder. I realized I needed to remove it when I noticed that some functions in the Kotlin/Native stdlib were missing, and the library path pointed to ~/.konan
