Cross compile node-v12.* and above, compilation fails

[Jack-he1233]

Hello, I cross-compile the node of armV8 architecture on ubuntu20, and use the command as follows:
./configure --prefix=*/node-v12.18.3 --dest-cpu=arm64 --dest-os=linux --without-snapshot --cross-compiling --without-intl
make -j8

What steps will reproduce the bug?

(1)Use the tool chain "gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu"
(2)Import environment variables
(3)Enter the source code file of node-12.18.3 and execute：
./configure --prefix=*/node-v12.18.3 --dest-cpu=arm64 --dest-os=linux --without-snapshot --cross-compiling --without-intl
make -j8
(4)Error message appears：

How often does it reproduce? Is there a required condition?

Inevitable event

What is the expected behavior?

The binary node is successfully generated in the "*/node-v12.18.3/out/Release" directory

What do you see instead?

The error message is as above

Is there a solution to this problem?

[gengjiawen]

As far as I know, our current toolchain only target on armv7 ? Will armv7 an option for you ?
cc @rvagg @nodejs/platform-arm

[rvagg]

hm, we don't cross with arm64 in our CI because the native hardware we use is very fast so I can't guarantee it'll work but I don't see why not.

It looks to me like a problem selecting the host compiler so you're not getting binaries that can run on your native arch. Look back through the compile output to see how bytecode_builtins_list_generator is being generated.

You have:

export CC_host="gcc"
export CXX_host="g++"

Can you check that gcc and g++ actually point to a working, native compiler and not a cross? These are the bits that should be doing the native compile portion.

@gengjiawen Can you share the toolchain address of your cross-compiled node of armV7 architecture?

@gengjiawen Can you share the toolchain address of your cross-compiled node of armV7 architecture?

Sure. But you need to know docker.

After removing the "--with-snapshot" parameter, you can successfully cross-compile. The "--with-snapshot" parameter has certain limitations in cross-compilation
