wabt fails to build with GCC 15

[sergiodj]

Hi,

I'm currently building wabt from source and get the following build failure with GCC 15:

The failure comes from the gtest third party module, but it's affecting wabt so I'm filing the bug here.

Thanks.

Do you need to run the tests? If not then presumably -DBUILD_TESTS=OFF in your cmake command should work around it for now?

Thanks for the reply. We're not currently running build time tests, so I went ahead and used the flag you suggested. The package builds fine with GCC 15 now.

It would be great to have this fixed more permanently, but I understand that this would require more effort.

Thanks.
