I wanted this morning to build an homemade version of mozilla minefield, using trunk source code as I do everyday or so.

But since I installed gcc 4.6 using testing repository, I cannot get it to be built. So I reported the bug on mozilla bugzilla, cf

I wanted to verify if it was related to gcc 4.6 at all.

So, after cleaning ccache cache, I grabbed xulrunner tarball, and launch build process using makepkg.

And it won't work. Here is the error log :

Steps to reproduce:

Upgrade gcc version and try to build xulrunner.

Probably related to "G++ no longer allows objects of const-qualified type to be default initialized unless the type has a user-declared default constructor." in latest GCC changes. g++ has become more strict in its checking, add -fpermissive to your CXXFLAGS to work around this.

Ok. Will add it to my .mozconfig and I will tell you.

It worked. Thanks for the tip !

I think they'll be more software which will be broken.

Unassigning me. This is not a gcc bug.

Well, it is a mozilla bug. Closing ?
