fatal error: 'third_party/fp16/src/include/fp16.h' file not found

[Andreas Beil]

Hello community,

i try to build 12.4-lkgr on Windows. Building 12.3-lkgr worked at least for the "monolith" configuration.

The build shows the following error:

../../../../../../src/objects/elements.cc(28,10): fatal error: 'third_party/fp16/src/include/fp16.h' file not found
28 | #include "third_party/fp16/src/include/fp16.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Either on the build machine and also in the online view of the repository, the mentioned file is not available.

I wonder how the code can be build at all. Do i miss anything?

Any hint how to handle this?

Regards,

  Andreas

Hi Andreas,

Did you try to run `gclient sync`? I don't know anything about this file, but such problems often get solved with a `gclient sync`.

Regards,

Andreas

Hi Andreas,

in fact i cleaned the whole repository and retrieved it from scratch. I can do this again ...

But as described, the file is also not available in the chromium git repository:

https://chromium.googlesource.com/v8/v8.git/+/refs/heads/12.4-lkgr/third_party/fp16/

Hi Andreas,

I assume that the file gets loaded with the DEPS rule in [1], so I would assume a `gclient sync` would fetch it. I have the file in my checkout. You can also download the file manually from the repository mentioned in [1].

Regards,

Andreas

Hi Andreas,

i think you are right :-)

I'm building v8 using a special script, which is not using 'gclient' (and i was not aware that that's the case :-( ). After your hint i checked how the script works and found the reason.

At least this is a "Takeaway" for myself.

Thank you very much for your response!
