Same code works fine and build is successful in mac OS.

Any help in what i might be doing wrong or have to do extra in windows OS?

I had this same issue.

This user had the same problem:

https://groups.google.com/g/v8-users/c/aVnVmDKkt8Q/m/jBSsug5tAAAJ

I notice that v8_heap_base_headers is a header-only target in BUILD.gn,

but it is defined as "v8_source_set()" which ends up as a lib.

If you change the line in BUILD.gn:

v8_source_set("v8_heap_base_headers") {

to

v8_header_set("v8_heap_base_headers") {

It is around the line 5544 or 5653 depending on which version you are looking at.

It changes to a virtual target, doesn't build a lib, and works!

Note that "gn" source_set() normally builds virtual targets, but the v8_source_set() seems to behave differently.

DEVS can you please patch the BUILD.gn file if you agree?

I'm not in a position to make a PR/MR/contribution right now.

Thanks!

Paul
