Hi, can you be a little more specific ? Exactly how are you compiling/linking your code (in the Visual Studio environment, directly using the cc65 suite...), and do the calls to open() or read() also flag the same errors? Have you checked the spelling ("l" and not "1") ? We can't provide help without more information. lseek() works fine with cc65, the cc65 assembler, even my PLASMA interpreter that I'm writing.

VS Code environment under Windows 10,
CC65 newest build within WSL2 Ubuntu
all other API functions are visible to VSCode and works
no typo errors
open() read_xram() write_xram() without any issues
lseek is the only one problematic

PS. under LLVMOS lseek() works without problems

Maybe you forgot #include <unistd.h> which would make it undeclared.

You've hit the nail on the head :)
