This indicates a problem with compiler. Please see if you can generate a preprocessed file by adding the "-P" option to the compilation options for native_backend_gnome_x.cc. We can investigate the problem once you send us the resulting .i file along with full compilation optons.

Thanks,

mark. first of all ,thanks.

have you compiled chromium before?

i`m using "gclient sync" ( recent subversion checkout).

read "http://code.google.com/p/chromium/wiki/LinuxBuildInstructionsPrerequisites"

andhttp://dev.chromium.org/developers/how-tos/get-the-code

andhttp://dev.chromium.org/developers/how-tos/install-depot-tools

finally readhttp://code.google.com/p/chromium/wiki/LinuxMakeBuild

[Mark_S_Intel1]

I have not built chromium before. I will look into it and get back to you.

Thanks,

Intel Composer XE update 1 (package name l_ccompxe_2011.1.107) is now available at https://registrationcenter.intel.com/RegCenter/Download.aspx?productid=1414. Can you try the new update and see if it resolves this problem?

Thanks,
--mark

[kuh3h3]

thanks for compiler update link.

new compiler could resolve "native_backend_gnome_x.c"internal error.

but with same option occurred new error.

my gcc compiles well the file.

[Mark_S_Intel1]

The development team has reproduced the problem and is looking into it. We will
let you know when this issue is resolved. In the mean time you may be able to work around this problem if you replace the unnamed namespace with the construction described in the C++ standard below:

An unnamed-namespace-definition behaves as if it were replaced by
namespace unique { /* empty body */ }
using namespace unique;
namespace unique { namespace-body }
where all occurrences of unique in a translation unit are replaced by the same identifier and this identifier
differs from all other identifiers in the entire program.

Example:

$ cat test.cc
// bad case
#include
namespace {
class A {
public:
virtual void foo() = 0;
void bar() {
std::cout << &A::foo;
}
};
} //namespace

$ cat test1.cc
//good case
#include
namespace my_ns {}
using namespace my_ns;
namespace my_ns{
class A {
public:
virtual void foo() = 0;
void bar() {
std::cout << &A::foo;
}
};
} //namespace

Could you please let us know if the proposed workaround works for you?

Thanks,

[kuh3h3]

sorry for too late reply.

your workaround works well for me.

but it is not easy to compile chromium.

new error always comes out.

this time, new error com from v8.

from searching web, i knew this is already known problem but there is still no fix.

i used recent compiler(12.0.2.137)

Thanks for the test case; I was able to reproduce the problem. I will investigate and get back to you.

The problem is thatline66707 is part of an explicit request to instantiate a member function of an instantiation of the Dictionary class. Line 66705 is an explicit request to instantiate the same instantiation of the Dictionary class -- which is interpreted as an explicit request to instantiate all the member functions of that template class. So the explicit instantiations of the member functions are redundant.

The workaround isto disable the diagnostic with-wd803.
