I am trying to compile V8 in debug with the following build args:
is_clang=true is_component_build=false v8_monolithic=true
treat_warnings_as_errors=false v8_use_external_startup_data=false
use_sysroot=false use_custom_libcxx=false clang_use_chrome_plugins=false
target_cpu="x64" is_debug=true use_debug_fission=true
I get the following error:
In file included from
../../../../../third-party/v8/v8/test/unittests/base/template-utils-unittest.cc:5:
../../../../../third-party/v8/v8/src/base/template-utils.h:58:71: error:
expected expression
struct has_output_operator<T, decltype(void(std::declval<std::ostream&>()
^
../../../../../third-party/v8/v8/src/base/template-utils.h:58:63: error: no
member named 'ostream' in namespace 'std'
struct has_output_operator<T, decltype(void(std::declval<std::ostream&>()
~~~~~^
I compile with clang 10.0.0 and the GNU standard library 10.1.0. I suppose
the error occurs because in a recent version of the STL, <ostream> is not
transitively included anymore. In template-utils.h, the include of
<ostream> is indeed missing.
