Hi everyone,
I'm trying to embed V8 into a C++ project currently and keep encountering
issues when linking V8. Currently i'm following the instructions on
https://v8.dev/docs/embed and doing this on Linux. After building V8 with
these parameters
gn gen out.gn/library --args='is_debug=false is_component_build=false
v8_enable_i18n_support=false is_clang=true v8_monolithic=true
target_cpu="x64" v8_use_external_startup_data=false'
and attempting to link to the libv8_monolith.a static library it throws a
bunch of undefined reference errors to the standard library e.g.,
undefined reference to `std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char>
>::__init_copy_ctor_external(char const*, unsigned long)'
I've setup my default compiler to use clang with the LLVM standard library
and using nm have determined that V8 is being built with clang and the LLVM
std library since it outputs std::__1:: function symbols.
I've also forced libc++ to be used in the cmake project that is trying to
link to the V8 library with cmake commands like so
set(CMAKE_CXX_STANDARD_LIBRARIES "-stdlib=libc++")
set(CMAKE_C_FLAGS "-stdlib=libc++")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -stdlib=libc++
-lc++abi")
I'm really at a loss at what could be causing this issue because both the
library and my project should be using the same standard library. Any
advice?
