It won't build on Windows

I keep getting this error, nothing builds:

6>C:\Users\spook\Dropbox\Desktop\ggml\examples\gpt-j\main.cpp(15,10): fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory

I noticed that yesterday .... is able to build almost all binaries except those :-/

had same errors for starcoder, you need to make 4 changes in examples\starcoder\main.cpp to compile:
15: #include <io.h> (instead of #include <unistd.h>)
204:
struct ggml_init_params params = {
ctx_size,
NULL,
false
};
instead of:
struct ggml_init_params params = {
.mem_size = ctx_size,
.mem_buffer = NULL,
.no_alloc = false,
};
430:
struct ggml_init_params params = {
buf_size,
buf,
false
};
instead of:
struct ggml_init_params params = {
.mem_size = buf_size,
.mem_buffer = buf,
.no_alloc = false,
};
724:
if( !isatty(_fileno(stdin)) ){
instead of:
if( !isatty(STDIN_FILENO) ){

scratch that i'm not getting any output from it so that 724 line is probably wrong

@ukiyocode Your solution is correct, but you also need to call ggml_time_init(); at the beginning of the main().
I think it's specific to MSVC/MINGW compilers for whatever reason (check ggml.c:403).

@eublefar Thx, it works now. Someone already added your line to the repo, so all you have to do now is the 4 changes i mentioned b4.
