Problem with AMI on GCC 4.7

mefoster

Hello all,

Here's a small test .ice file:

module test {
    interface TestInterface {
        ["ami"] void doTest ();
    };
};

If I run slice2cpp on this and then gcc -I. Test.cpp, I get the following errors:

In file included from ./Test.h:29:0,
from Test.cpp:21:

Hi,

Yes we are aware of this problem with gcc 4.7 and clang which have changed the scoping rules. A fix will be included in the next Ice release (which is still few months away). In the meantime, you should be able to use the patch posted here if you need to compile Ice with gcc 4.7.

Cheers,
Benoit.
