Invalid or corrupted .lib file

[anastasia...@gmail.com]

Hello! I've just compiled V8 as static libraries, everything compiled fine, but when I try to include thiese .lib files into my VS project - it says "Invalid or corrupted library" for v8_base_without_compiler.lib

I am on Windows 10 x64, Visual Studio 2017, lastest SDKs

My GN build config:

is_debug = false
target_cpu = "x64"
is_component_build = false
v8_static_library = true

My source code part:

https://pastebin.com/jhwmsX8R

If I need to provide more information - please inform me

Thank you!

When building for Visual Studio, try adding:

is_clang=false

Thank you very much! But now I have another problem. While building by project - it says:

unresolved external symbol "__imp_timeGetTime"

Any ideas how to solve it?

I solved it! Thank you! I had to add:

#pragma comment(lib, "winmm.lib")

How can I compile v8 without using snapshot .bin files?

I'm not sure but there seems to be an option called "v8_use_snapshot". Try setting that to false and see what happens?

[Anastasia Riza]

I've done it, but it crashes on Isolate::New :(

My gn options:

is_debug = false
target_cpu = "x64"

v8_use_snapshot = false
v8_use_external_startup_data = false

is_component_build = false
v8_static_library = true

is_clang = false
use_lld = false
treat_warnings_as_errors = false

I read that it crashes because can't find .bin files, but I compiled it with no snapshot...

Probably you have account in some messanger? I am new in v8 embedding, I could ask some questions if you don't mind, it would be better than here I think

In that case, I am sorry but I don't know what to suggest, other than to try stepping through the source.

Unfortunately, I am not an expert in V8, though I did recognize the problem that you described in your original post.

Probably you know someone who can help?

I can try to make it with snapshot files, but I get only natives_blob.bin, but I can't see snapshot_blob.bin

Maybe you know how to get snapshot_blob.bin?

There's two relevant gn flags:

v8_use_snapshot: Enables snapshot support.

v8_use_external_startup_data: enables 'external' snapshots, i.e. the snapshot_blob.bin file.

It sounds like you want both of these flags set to true.

Another option that is specifically intended to be simple to use for embedders is a monolithic build, which produces a single v8_monolith.a static library that includes the snapshot and can be included into embedder projects. The gn flags there would be something like this:

  v8_use_external_startup_data = false

  v8_monolithic = true

  is_component_build = false

  is_clang = false

  [... whatever other gn flags you need ...]
