node: Do not use shared `abseil-cpp` #25582

vidplace7 · 2024-12-19T23:38:52Z

Maintainer: @nxhack
Compile tested: OpenWRT One master/snapshot

Description:
Fix nodejs compile errors after the introduction of abseil-cpp in #25565

Extends the existing gyp_tools patch to force v8 to use the bundled (chromium) abseil-cpp.

Resolves #25483

Thanks to @vortexilation for pointing out this issue.

Hi @vidplace7

Question.

The source code distributed by node.js includes abseil-cpp.

. /deps/v8/third_party/abseil-cpp

It appears to be used in the current package.

. /out/Release/obj.host/v8_abseil
. /out/Release/obj.host/v8_abseil/deps/v8/third_party/abseil-cpp
. /out/Release/obj.host/tools/v8_gypfiles/libv8_abseil.a.ar-file-list
. /out/Release/obj.host/tools/v8_gypfiles/libv8_abseil.a
. /out/Release/obj.target/v8_abseil
. /out/Release/obj.target/v8_abseil/deps/v8/third_party/abseil-cpp
. /out/Release/obj.target/tools/v8_gypfiles/libv8_abseil.a.ar-file-list
. /out/Release/obj.target/tools/v8_gypfiles/libv8_abseil.a

Please tell us why this modification is necessary for this package.

vidplace7 · 2024-12-20T00:27:59Z

@nxhack a shared abseil-cpp package was introduced in #25565, for use in protobuf (and other packages that use the standard abseil-cpp LTS version / don't bundle it themselves).

Without this patch, if the shared abseil-cpp library package is installed to the staging_dir before node is compiled, node (v8) will attempt to use it, and fail spectacularly (as it's a different variant/version).

nxhack · 2024-12-20T00:31:40Z

Understood.
I will now test to see if it builds correctly on all architectures. Please give me some time.

nxhack · 2024-12-20T03:44:11Z

It seems that the host build of node.js fails when abseil-cpp is installed. We will consider a workaround.
It fails regardless of whether or not hostpkg abseil-cpp is installed.

nxhack · 2024-12-20T04:39:47Z

It's a very dirty patch, but it worked!

vortexilation · 2024-12-20T06:41:03Z

This PR seems doesn't work but patch above by @nxhack is working.

nxhack · 2024-12-20T22:27:50Z

I have confirmed that it builds and runs on aarch64, arm, i386, x86_64 with my patch applied.

vortexilation · 2024-12-21T04:34:55Z

Hmm, can you please try with glibc on x86_64?

nxhack · 2024-12-21T10:59:28Z

@vortexilation

I am verifying a simplified version of the above patch. musl does not give me any problems at all, but glibc gives me the following error. I will consider a countermeasure.

With this patch, glibc seems to be ok.
I will test it again. It will take some time.

Your first patch is working for me, also the newest one (glibc). Thanks.
