Building V8JS on Debian 11 Bullseye (Docker/Laradock) #471

Closed jakedowns closed 2 years ago

jakedowns commented 3 years ago

Hello, taking a shot in the dark here, but I've been struggling for a few days to get the v8js extension & classes working properly in my Laradock php-fpm container.

Originally, it was on Debian 10, but through trial and error, I ended up needing to upgrade it to 11 to resolve an issue with libstdc++6 not including symbols for GLIBCXX_3.4.26 until the version of the package for Debian 11.

my current blocker is when i run make in the v8js directory, I get this error output:

/tmp/v8js/v8js_v8.cc:67:2: error: no matching function for call to 'v8::V8::InitializeExternalStartupData(const char [29], const char [30])'
   67 |  );

Not that I'd want to run it without snapshots, but I tried adding DV8_USE_SNAPSHOT=0. It did not prevent the above error.

./configure --with-v8js=/opt/v8 LDFLAGS="-lstdc++" CPPFLAGS="-DV8_COMPRESS_POINTERS -DV8_USE_SNAPSHOT=0"

So, this error is what happens when i try to compile with the recommended version of 8.0.426.30 in the Linux readme

Looking at the OmahaProxy, I see Linux Stable is currently using v8 version 9.4.146.21. When I compile that version of v8 and then try to make v8js, I get the same error.

If i try installing via pecl install v8js I get the following error:

configure: error: Please reinstall the v8 distribution ``` root@b977271ad17e:/tmp/v8# export PATH="/usr/include/nodejs/deps/v8/include/:$PATH" root@b977271ad17e:/tmp/v8# pecl install v8js downloading v8js-2.1.2.tgz ...

On debian 11, libv8-dev remaps to libnode-dev Libnode-dev seems to have v8 header files in this directory: /usr/include/nodejs/deps/v8/include/

Tho, even if I export that directory in my $PATH variable: export PATH="/usr/include/nodejs/deps/v8/include/:$PATH" pecl install script still says i need to reinstall v8 dist

I'll update this ticket as I continue to work through the issue.

update: using dpkg -L libnode-dev | grep v8 I found the libv8.so file is installed to: /usr/lib/x86_64-linux-gnu/ so, if I export THAT to my path export PATH="/usr/lib/x86_64-linux-gnu:$PATH" and then run pecl install v8js and tell it libv8 prefix is /usr/lib/x86_64-linux-gnu/ I still get:

checking for V8 Javascript Engine... yes, shared
checking for V8 files in default path... not found
configure: error: Please reinstall the v8 distribution

I wonder tho, if it's because libnode-dev just does a symlink to libnode.so ? lrwxrwxrwx 1 root root 10 Aug 11 19:06 libv8.so -> libnode.so

Update: finally got configure to run.

basically i cleared out /opt/v8/lib/ & /opt/v8/include/

then, I used cp -Lr (L flag to dereference the symbolic link) to copy all the libv8.so files from libnode-dev `cp -Lr /usr/lib/x86_64-linux-gnu/libv8.so /opt/v8/include`

then, since it didn't look like libnode-dev installed the needed blob.bin files, I copied those from my failed build of v8 `cp out.gn/x64.release/lib.so out.gn/x64.release/*_blob.bin out.gn/x64.release/icudtl.dat /opt/v8/lib/` (hopefully they still work)

so, then I run Make and it completes with only warnings, no errors. But then I run make test, and all but 3 fail.

ugh, i forgot to run make clean last time, so i may have gotten a false negative. whatever. ran make clean and now i'm trying to rebuild from scratch with 7.8.279 which is the version of v8 that libnode-dev uses Result: 47 tests pass, 128 tests failing

Closing this one now as V8 9.x+ is now required.
