Hi,

Thanks a lot, that helps me to make one more step :)

I set :

┌────
│     (arguments
│         `(#:phases
│            (modify-phases %standard-phases
│          (add-before 'configure 'set-source
│            (lambda _
│              (setenv "V8_FROM_SOURCE" "1")
│              (setenv "RUST_BACKTRACE" "1")
│              (setenv "CLANG_BASE_PATH" (getenv "CMAKE_PREFIX_PATH"))
│              #t)))
└────

I also try C_INCLUDE_PATH

and native input :

┌────
│ 	(native-inputs (list ninja gn clang-toolchain ccache clang))
└────

I have now another problem during compilation of v8, i don’t understand why “clang” path is not well recognized by the buildscript, test is defined here :

<https://github.com/denoland/rusty_v8/blob/main/build.rs#L517>

The backtrace :

error: failed to run custom build command for `v8 v0.49.0`

Caused by:
  process didn’t exit successfully: `/tmp/guix-build-rust-deno-1.25.2.drv-0/deno-1.25.2/target/release/build/v8-bbb68ec56db1d802/build-script-build` (exit status: 101)
