Gen AI suggestions to solve the build error: • Detected Error: Template-id related C++20 compatibility warnings leading to build failure: • Error Category: Build Configuration • Failure Point: V8 engine compilation during Node.js build process • Root Cause Analysis: The build is failing due to C++20 compatibility issues in V8's template usage, specifically in the object-macros.h and fixed-array.h files. The compiler is treating template-id syntax in constructors as errors under C++20 standards. • Suggested Fix: - name: Configure and build
runs: |
export CXXFLAGS="${CXXFLAGS} -std=c++17"
# Rest of the existing configure and build commands...• Explanation:

Gen AI suggestions to solve the build error: • Detected Error: Template-id not allowed for constructor in C++20 [-Wtemplate-id-cdtor] • Error Category: Build Configuration • Failure Point: V8 engine compilation during Node.js build process • Root Cause Analysis: The error occurs because the V8 engine's code uses template constructor syntax that's no longer allowed in C++20. This is a compatibility issue between the V8 codebase and newer C++ standards. • Suggested Fix: Add the following to the "Configure and build" step to force using C++17: export CXXFLAGS="${CXXFLAGS} -std=c++17"Modified section should look like: - name: Configure and build
runs: |
# Add defines recommended in libuv readme.
common_flags="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64"
# Force C++17 to avoid C++20 template constructor issues
export CXXFLAGS="${CXXFLAGS} -std=c++17"
# Existing optimization flags
export CFLAGS="${CFLAGS/-Os/-O2} $common_flags"
export CXXFLAGS="${CXXFLAGS/-Os/-O2} $common_flags"
export CPPFLAGS="${CPPFLAGS/-Os/-O2} $common_flags"• Explanation: The V8 engine's codebase uses template constructor syntax that was deprecated and removed in C++20. By explicitly setting the C++ standard to C++17, we avoid these compatibility issues while maintaining functionality. This is a known issue with V8 when building with newer compiler versions that default to C++20. • Additional Notes:

…e code, nodejs-22 already using gnu++17 Signed-off-by: Debasish Biswas <debasishbsws.dev@gmail.com>
A recent fix was added to our node-16 package as part of this PR:
Believe this should also fix the build error here, so i've ported over the change
