Error while generating a database for V8 #112

I am not familiar with the V8 build, but there are a few common reasons for
that error message. The first possibility is that the build is happening in
a completely different directory than the one that you ran the command in.
CodeQL is only monitoring the current directory, so it won't see source
files that are built elsewhere. The second possibility is that the build is
using caching. You need to make sure that it is doing a full rebuild so
that CodeQL sees all the compiler invocations.
Hope that helps,
Kev

Im trying to create a database for V8, but so far I didn't manage to make
it work.
Im using the following command to build V8
codeql database create v8-database --language=cpp --command="ninja -C out/
d8"
It builds fine, but the database generation process fails with the
following error A fatal error occurred: No source code was seen during
the build
From what I see Ninja is supported "
https://help.semmle.com/wiki/pages/viewpage.action?pageId=24085367", so
no idea of why this is failing.
You can find the full log here:

Pd: I know that there is already a pregenerated database for V8 (
https://semmle.com/large-oss-projects), but its quite old.

Thanks Kevin! It takes a while to compile as expected, but it works, codeql successfully generated the DB this way! |
